INSTALLATION AND USE

On the Wii / Wii U's Virtual Wii, to use Snes9x RX you will need to copy over the "apps" and "snes9xgx" folders (directories) from the .zip to your SD Card. It comes pre-packaged in the Homebrew Channel format (which you will use to launch the emulator). Once you've copied the directories to your SD Card you will need to place your ROM image(s) into "\snes9xgx\roms" directory. Optionally, you can place cheat code files and artwork/covers in their respectively named folders inside the "\snes9xgx" directory. If they are not present, the folders will be created at second run, in case you want to acquire the files later. Once you are done, you can proceed to run the emulator. Additionally, you can install the Snes9x RX Forwarder Channel in your Wii or vWii System Menu (it points to "\apps\Snes9xRX"), or the special Snes9x RX Channel for Wii U, which fully installs to your console and reads the configuration and necessary files from your device "\snes9xgx" folder, be it SD or USB.

In the case of the Wii U Channel version, it has the added benefit of taking advantage of the extra CPU power available, on the condition that you run the Wii U homebrew app "sign_c2w_patcher" first, to unlock the so-called "Wii U Overclocked Mode", which simply makes the console avoid the CPU underclock (729 MHz) to run Wii software at the native Wii U's speed (1.24 GHz), so it is completely safe to use.

You can use WUP Installer GX2 or the WUP Installer Y Mod to install the channel, loaded through the Wii U's Homebrew Launcher or through a WUHB package (Aroma).

After installing the Wii U channel (forwarder) onto your console, proceed to use whatever special build suits your preference, by unzipping it to the root of your SD card or USB drive (both on FAT16 or FAT32), where it will extract the folder "apps" and "snes9xgx", pre-packaged in their respective .zip archive.

It is important to note, when you use the Wii U's overclocked mode, you are limited to use the SD as the storage medium for all your files. No workarounds, as this is currently a console limitation.

INITIAL SETUP

The first time you run Snes9x RX it will create a new "settingsRX.xml" file on the SD/USB Card which stores the configuration of the emulator. So when you run Snes9x RX, it will automatically detect your storage medium and bring you to the ROM selection screen. If you want to run a game with the default settings, then just highlight the game and press 'A' on it and it will load. However, you can configure Snes9x RX to your liking.

CONFIGURATION

To configure Snes9x RX, press 'A' on the "Settings" box. This will bring up the "Settings" screen where you can configure the "Saving & Loading", "Menu", and "Network". You can also restore the settings to their initial values by clicking on the "Reset Settings", read the Credits / activate supported USB controllers (better explained in the USB Controllers section below), or you can just return to the ROM selection screen by clicking on "Go Back".

SETTINGS

SAVING & LOADING

From this setup option you can configure the way Snes9x RX loads and saves. Your options are Load Device, Save Device, Load Folder, Save Folder, Auto Load and Auto Save. Clicking on all of the options will let you toggle through their settings. Those labeled with "folder" will bring up a text box where you can enter any other path you wish to use, in case you have the need to customize it. This is also true for the Cheats, Screenshots, Covers, and Artwork options.

Snes9x RX has two types of saves - one is the SRAM, which is the save game data (this is only applicable if the game you're playing supports battery saving), and the other is Snapshots, which are real time saves. Real time saves allow you to save your game in it's current state and resume it at a later time.

	• Load Device -	SD, USB, DVD, Network and Auto Detect

	• Save Device - SD, USB, Network and Auto Detect

	• Auto Load - SRAM, Snapshot and Off

	• Auto Save - SRAM, Snapshot, Both and Off

You can also toggle the option to append 'Auto' into the filename of all the automatic SRAM saves that the emulator creates, whenever you play a supported battery saving cartridge.

MENU

This settings screen will allow you to customize a few aspects on how the Menu works including the Exit Action, Wiimote Orientation (for navigating through the menus), Music Volume, Sound Effects Volume, Satellaview BIOS (better explained in the Satellaview section below), Language (all menus), the type of Preview Image you would like to see on the Choose Game screen, a toggle to show or hide the "New SRAM" button inside the Save/Load/Delete menus, and Display Virtual Memory, the latter two shown inside the Game Menu.

The Exit Action can be set to "Return to Wii Menu", "Power off Wii", "Return to Loader" or simply "Auto", which will determine the Exit Action based on the context of how you load the emulator.

NETWORK

If you're going to be using your Network (LAN) to load and/or save from, you will need to enter in the SMB share settings you've setup on your computer via this settings menu. You will need to enter in the SMB Share IP, SMB Share Name, SMB Share Username and SMB Share Password. If you do not have a password on your SMB share, then set the SMB Share Password to "0".

FILE BROWSER (Choose Game)

The File Browser will automatically load when you start the emulator, listing the contents of the "\snes9xgx\roms" directory on your SD card or USB drive. You can specify a different default directory to load games from (Settings -> Saving & Loading -> Load Folder), or simply navigate to another one by pressing on "Up One Level", going back as far as the Device Selection. It will autosave the current directory for you, if you happen to load any ROM from it. To launch a game (which can be either uncompressed, or inside a ZIP or 7Z archive) simply click on the title and it will load. In the case of 7z compressed files, you will be presented first with a list of all the supported games inside the compressed archive.

GAMEPLAY MENU

Once you load a game, you can access a special emulator menu by pressing the Wii/Wii U controller's 'Home' button / Gamecube controller's 'C-stick Left'. If you're using any other input controller on the Wiimote extension that doesn't have a 'Home' button, press 'Start + B + A'. If you use an special converter to connect other types of controllers on the Gamecube ports, simply press the button combination 'Start + B + A'. This action will bring up a special Game Menu that contains the "Save", "Load", "Delete", "Game Settings", "Screenshot" and "Reset" options.

From this menu, you can also return to the Choose Game screen by selecting "Main Menu". To leave the menu and resume gameplay, select "Close" or press 'Home' (Wii or Wii U Controllers) or 'Start' (Gamecube controllers).

SAVE / LOAD / DELETE

The "Save" option will allow you to save either your SRAM (cartridge save on the internal battery) or a game Snapshot (frozen game state). Once you've selected "Save", two options will appear named "New Snapshot" - "New SRAM". Clicking on either of these will create a new save file, which you can overwrite if you need to by selecting it. The "Load" option will allow you to load any saved SRAM or Snapshot. Finally, the "Delete" option will let you select and delete any of your snapshots or SRAM saves.

SCREENSHOT

This button takes a picture of the screen you're in at the gameplay moment, for Preview's use on the File Browser's "Choose a game".

RESET

"Reset" will just reset the game, as the real console behavior.

GAME SETTINGS

If you pick "Game Settings", you can adjust other special options, which are thoroughly covered in the following sections.

GAME SETTINGS

BUTTON MAPPINGS

Inside the "Button Mappings" settings menu, you can configure the button mappings for SNES peripherals like the SNES Controller, Mouse, Super Scope, and the Konami's Justifier. You'll have the option to remap almost all the controllers already supported by the emulator (except the Retrode 2 USB, Xbox 360 controller, Hornet Gamepad, or the DualShock 3).

Once you select a controller to configure, you will be presented with a complete list of the SNES Gamepad buttons you can remap. To set any buttons, simply pick and click. Snes9x RX will prompt you to press the new physical button you want to assign to the virtual button you've selected. Below is a list of each controller, followed by the input devices and the default values for those devices.

BUTTON MAPPINGS - OTHER MAPPINGS

This sub-menu offers you four options:

• Turbo Mode: allows you to turn ON (Default) or OFF the Turbo Mode feature.

• Turbo Mode Button: allows you to remap the feature to any other button, by
cycling through the available labeled options represented on the supported
physical controllers.

• Menu Toggle: allows you to choose which buttons or key combo will be
available to you to return from the game to the Gameplay Menu.

• Map YXBA to Right Stick: offers you the choice to enable the mapping of the
Y+X+B+A buttons to the Right Stick on the supported controllers with analog
joysticks, so shooters like Smash T.V. and Total Carnage are more enjoyable.
If you're using a Gamecube controller, remember to set the "Menu Toggle" to
"Start (PLUS)+B+A" so it doesn't activate fast-forward, or just disable it
by using the "Turbo Mode" toggle.

AUDIO

The Super Nintendo / Super Famicom creates audio through the Nintendo S-SMP, a wavetable synthesizer and dedicated sound module designed and manufactured by Sony.

This APU (Audio Processing Unit), which functions as a sound co-processor to offload the work done by the console's main CPU, mixes up to 8 simultaneous voices in 16-bit Stereo, at a max sample rate of 32,000 kHz. Sound samples are stored in the APU's 64KB PSRAM in compressed (BRR) format.

All these samples together are output with a specific process of audio interpolation, named Gaussian filtering, the APU's native method, with its own set of pros and cons.

Audio interpolation is a method of making digital audio sound better than it really is, to improve the listening experience.

The interpolation filter options presented in this menu allow you to fine tune the produced sound with other filters, which subtly alter the source, so it's up to your preferences to change it. Below is a short explanation for each option:

• Gaussian: the most accurate representation to how the console sounded.
It minimizes / limits aliasing and might produce better bass in certain
sounds. However, the sound will overall be a bit more muffled or soft,
because of the low-pass filter applied to the sound output.

• Linear: the simplest form of interpolation. Sounds a bit clearer.
The problem with linear interpolation is that it makes straight lines
between each sound sample, and sound waves don't follow straight paths.

• Cubic: might give the brightest sound, it tries to reproduce a more
natural waveform by "bending" the interpolated points around the original
samples. This method gives an interpolating polynomial that is smoother
and has smaller error than some other interpolating polynomials.

• Sinc: Linear and Cubic allow aliasing (this is the misidentification
of a signal frequency, which might introduce distortion or other artifacts
into the recording). Sinc leaves samples sounding essentially as they
do in their raw form.

• None: entirely disables interpolation.

The "Stereo Reverse" option will allow you to swap the Left/Right audio channels, for audio tests, in case your cables are wired different, or they've been swapped accidentally.

The "Mute" option is self-explanatory. It will completely turn off all audio output from the game, in case you don't have an inmediate way to mute your TV or sound equipment. This also has the side-effect of giving you a couple of extra FPS in-game, due to sound emulation being off the CPU workload. Pretty much the only games you would notice this speed difference, are the SNES titles that integrate the Super FX chip.

VIDEO

The "Video" settings screen will allow you to configure various settings, including the Rendering method, Aspect Ratio, Filtering, Screen Zoom, Screen Position and Video Mode. You can toggle the options for the first three selections by clicking on them.

• Rendering - Unfiltered (Raw pixels)
            - Filtered (Soft)
            - Filtered (Sharp)
            - Original (240p)
            - Filtered

• Aspect Ratio - 4:3 (original)
               - 16:9 correction

• Filtering - None
            - Scale2x
            - hq2x
            - hq2x Soft
            - hq2x Bold
            - Scanlines 25%
	        - Scanlines 50%

To use the "Original (240p)" rendering, make sure your LCD/LED display supports 240p, else you will have a black screen upon returning to the game, or your display will warn you that there is no signal. This is the most accurate rendition for the resolution from the original Super Nintendo, and will give you crisp unfiltered pixels, most ideally suited to enjoy on CRT TVs / CRT monitors. This rendering mode can even be coupled with modern TVs for use with scanline generators or line doublers, like the Framemeister, OSSC, or RetroTink.

Something to keep in mind, the Scanlines 25%/50% filters are not meant to be used with "Original (240p)" rendering, due to the lower resolution that's being output. They will make the screen flicker badly.

Also important to note, the Scanlines 25%/50% filtering modes will not work on games that utilize the Super Nintendo Hi-Res Mode. It will result in broken graphics (i.e.: A.S.P. Air Strike Patrol) or just no difference at all (i.e.: Super Buster Bros).

• Screen Zoom: this will bring up a menu where you can adjust the Zoom level
by using the clickable left and right arrows. The default setting is 100%.

• Screen Position: this will bring up a screen with four arrows that allows
you to move the position of the video output. You'll only need to use this
option if the screen is not centered. Combining this with the Zoom and
Scaling you should be able to get a proper display on your television.

• Video Mode: manually choose between the supported video standards for
your display. NTSC (480i), Progressive (480p), PAL (50Hz), PAL (60Hz),
or Automatic, the latter one being the recommended setting.

• SNES Hi-Res Mode: this will disable the games capacity to use the
SNES Hi-Res Mode, if you want to use the Scanlines filtering in those
games. It will of course break games that were intended to use the
feature (i.e.: texts in Secret of Mana, Seiken Densetsu 3, etc).

• Crosshair: this will disable the emulator's on-screen crosshair for all
Super Scope / Justifier games.

• Show Framerate: show the frames per second (FPS) on-screen.

• Show Local Time: show the the local time set on your Wii on-screen.

CONTROLLER

Toggle between compatible SNES peripherals that you wish to use your game with (wherever it is supported), be it two controllers, Multitap (for up to 4 players), Mouse, Superscope, or the Konami's Justifier lightgun.

CHEATS

This will allow you to enable/disable your Game Genie cheat codes. Check the in-depth section below.

EMULATOR HACKS

This will allow you to activate different options that will enhance or alter the gameplay. Check the in-depth section below.

CHEATS

Cheats are loaded from the "\snes9xgx\cheats" directory and must be in the SNES9X .CHT file format. They also must be named the same name as the game you're playing with the .cht extension. An example would be if you have a ROM called "Super Mario World.smc" you would need to name your .cht file to "Super Mario World.cht". You can find a link to a massive collection of Super Nintendo cheat codes in the Links section below.

EMULATOR HACKS

These hacks could significantly alter or improve the gameplay experience, depending on the game.

• Super FX Overclock: this special setting will overclock the speed of
the GSU-1 & GSU-2 chips -most commonly known as the Super FX chip- on every
supported title, which improves games with faster or smoother framerates.
This effect is most notable in games that pushed the original hardware to
its limits, like the Star Fox saga or Doom, for example.

When playing on the Gamecube, whose CPU is slower than the succeeding
consoles, it can give you better speeds on light FX games as
Super Mario World 2: Yoshi's Island.

You can have it at the Default chip speed (10.7 MHz GSU-1 / 21.4 MHz GSU-2),
or set it to 20 MHz, 40 MHz, or 60 MHz. Keep in mind that the majority of
the Super FX games and overclock don't mix well on the Gamecube and it
will slow the games to a crawl, as the console's CPU is not powerful enough.
The same is true with the Wii console, though you can push it to at least
60 MHz without too much trouble, the exception being the game Doom with
anything over 20 MHz, which can leave you with an unresponsive console
depending on the scene.

If you use the Snes9x RX Wii U Channel version along with the console's
"overclocked mode" (by opening the sign_c2w_patcher homebrew before running
the emulator), you can now perfectly enjoy the Super FX Overclock setting
speeds of 80 MHz, 100 MHz, and up to 120 MHz, which give a very nice boost
in framerate for these special games. These last three speed options are
hidden on the Gamecube port, as they are unusable for the reason explained
above.

• SNES CPU Overclock: this special setting will overclock the speed of
the virtual SNES CPU being emulated, which will mostly improve and/or
smooth framerates in games. Drastic examples of improvement are
Out of this World, NCAA Basketball, and the Top Gear series.
Set the setting to Default, Low, Medium, or Max. Be warned, there's a
handful of games that will not boot if the setting is anything but Default.
In those cases, you can workaround it by changing it after the game starts,
as most games will react to the setting in real time, others might require
a virtual Reset.

• Sprites per-line Limit: when disabled, this will allow the emulated
console to break the original hardware limitation of 32 sprites per-scanline
limit, so sprites don't dissappear or flicker. Specially useful for games
that show lots of sprites on screen (i.e.: Gradius III, BioMetal, etc).

• Satellaview BIOS: when disabled, this will boot the BS-X games directly
through the emulated console. The reason why this is an option, is because
not every Satellaview game has been correctly dumped yet, and some work
only by disabling the add-on, as the BIOS doesn't recognize the ROM
correctly due to the missing bits of data.

MSU-1 CO-PROCESSOR

The MSU-1 is a custom coprocessor that sits inside the game cartridge, not entirely unlike the Super FX, SDD-1, CX4, SA-1 or the DSP series, used in games such as Doom, Star Ocean, Mega Man X2, Kirby's Dream Land 3, or Top Gear 3000, respectively. This expansion chip was designed by byuu (later known as Near), the author of bsnes and higan, the most accurate to hardware, Super Nintendo / Super Famicom emulators ever made.

The enhancement chip enables playback of CD-quality audio (uncompressed 16-bit PCM at 44,100 kHz), along with full-motion video, and even the streaming of new graphic frames into games. Another neat trick is to store program data on it, copy this data into the SNES main RAM and execute it from there. All of this is possible as the MSU-1 addresses up to 4GB of data, far more than a typical SNES cartridge could ever hold.

SATELLAVIEW (BS-X)

To emulate the St. GIGA's satellite service, some of its exclusive games require the obligated use of the add-on's BIOS. You're free to use the japanese BIOS file, or the recommended english translated (No DRM) version.

The correct values for the file (English+No DRM, version 1.3) are: Size: 1.048.576 bytes CRC32: E5A91AD4 MD5: 96CF17BF589FCBFA6F8DE2DC84F19FA2 SHA-1: 4891D739A8A8B67923681BAD4FB67EDAB2E90E50

Rename the file and its extension to "BS-X.BIN", then put it inside the "snes9xgx" folder at the root of the device. (SD or USB)

Though the BIOS use is optional, it is required for a bunch of the titles, but specially, for the digital magazines.

If you need a place to get the correct file, check the Links section down below, and visit the BS-X Project website.

USB CONTROLLERS

To enable the Speedlink Hornet Gamepad or the Xbox 360 (wired) controller, there are two ways available:

Before loading Snes9x RX, connect your Xbox 360 wired controller. If the other USB port is populated (example: USB HDD, flash drive, DualShock 3) it should work the moment you start a game. For manual detection, when you're at the main screen (Choose Game), click on the emulator logo at the corner and check the status info at the bottom, to confirm detection. The same can be achieved by opening the Credits section inside "Settings".

Remember, the controller only works when in-game. You can swap your player/port number by simply pressing on the Xbox Guide button.

To enable the DualShock 3 (wired) controller, press and hold both minus (-) and plus (+) buttons in sequence, then release. You can do this in the Wiimote, or even the Wii U Pro Controller. The DS3 led #1 should light up once, and then the four leds. After that, press the PS button, it should be enabled for in-game use by now. You can do this before loading any game, for example.

TURBO MODE

Turbo Mode increases the playback speed of the game by about 2x. By default, to use it simply press and hold right on the 'C-stick' (yellow control stick on the Gamecube controller) or the right analog stick on the Wii Classic Controller / Wii Classic Controller Pro / Wii U Pro Controller for as long as you want gameplay to be faster. Release the stick/button whenever you want normal playback speed to resume.

Remember that this function can be disabled or remapped to other buttons inside the Game Menu (Game Settings -> Button Mappings -> Other Mappings).

IMPORTING AND EXPORTING SRAM

Snes9x RX includes the ability to load SRAM save files created with Snes9x version 1.52 and onwards on other platforms (Mac/PC/Linux/etc.), and to use the save file back to those.

To load a SRAM file on the Gamecube / Wii / Wii U from another platform, ensure the name of the new .SRM file matches the filename of the ROM on your device.

To use a Snes9x RX SRAM file on another platform, just do the opposite: copy the saved SRAM file to the other platform. You may have to rename the file or the extension to be what that version of Snes9x expects it to be, like .SRM to .SAV, for example.

AUTOBOOT MODE

Snes9x RX also sports an autoboot feature, for special use with custom forwarders made to look like Wii Virtual Console channels, or individual entries on your Homebrew Channel. To make use of this feature, just add the following lines to your meta.xml right between </long_description> and </app>, like the following example:

   </long_description>
   <arguments>
   <arg>sd:/snes9xgx/roms</arg>
   <arg>game.sfc</arg>
   </arguments>
   <ahb_access/>
 </app>

Use "sd:" OR "usb:" according to your media, adjust the path to the specific location of the ROM on your device, and replace "game.sfc" with the specific name of your game file (can be a .zip, too).

Make sure to set your configuration to your liking before using autoboot, as you won't be able to change the ones that are only accesible inside the Settings menu at the emulator's Main Menu / Game browser.

UPDATE HISTORY

[5.4.0 - October 15, 2022]

• Map YXBA to Right Stick (thanks InfiniteBlueGX!) Right stick can now be configured as YXBA, like what the Xbox 360 wired controller is configured by default with this emulator, specially useful for shooters like Smash TV and Total Carnage.

• Add option to choose the Emulator Menu toggle [InfiniteBlueGX] Choose between "Default (All Enabled)", "Home / C-Stick Left", or the universal button combo "Start+B+A / Start+1+2".

• UI navigation improvements. [InfiniteBlueGX] Pressing B / 1 will now Go Back from all menus and some sub-menus.

• Satellaview BIOS ON-OFF (thanks Tanooki16!) In RX, it was changed and adapted to be intuitive and easy to use. Enable or disable BS-X Satellaview BIOS boot through: "Settings -> Menu" or "Game Settings -> Emulator Hacks".

[5.3.0 - September 28, 2022]

• Upgraded Satellaview (BS-X) engine to latest Snes9x to date. This furthers up the game compatibility, by making use of the Satellaview BIOS. Though the file is optional, you'll want to use it for titles that make exclusive use of its functions. Some of the titles now playable are:

Inside the "Video" section, you can now choose three settings to overclock the virtual SNES CPU, to improve or smooth the framerate in games that originally struggled (i.e.: cutscenes in Flashback). It may also change the flow of the game entirely (i.e.: Skulljagger - Revolt of the Westicans). Experiment with the setting on your favorite games or other uncommon titles in your library.
• Updates for the Spanish language.
• Other tweaks.

• SNES Hi-Res Mode ON/OFF and Sprite Limit ON/OFF (thanks Tanooki16!)
• Important readme updates.
• Updates for the Spanish language.
• Other tweaks.

[5.0.0 - Abril 22, 2022]

[4.5.0 - November 22, 2019]

• Xbox 360 wired controller support! (thanks revvv!) Before loading Snes9x RX, connect your Xbox 360 wired controller. When you're at the main screen (Choose a game), click on the emulator logo at the corner of the screen and read the status info at the bottom, just to make sure it was properly detected. In some cases you won't need to do this, it will just work. Remember, the controller only works when in-game. You can swap your player/port number by simply pressing on the Xbox Guide button. Enjoy!

Right stick is configured as YXBA (essentially duplicating your buttons), specially useful for Smash TV fans like me =D

Some notes from revvv: "- If the Retrode does not react, you just have to restart Snes9x GX. I never had to restart HBC or the Wii. This happens with my fork, too. But not very often.

• Doom is a good testcase: My first build had a huge lag, but only with this game. After polling the Retrode only for player 1, the lag disappeared. (Doom is a single player game, so it's strange that they poll player 2.)"

[4.0.0 - July 28, 2019]

• Add Wii U GamePad support. [Fix94 - Tantric]
• Allow "Original" render mode to be selectable when using the Wii Options TV Resolution setting for "EDTV or HDTV (480p)" over component cables:

• This caters specifically to LCD / LED users with 240p supported displays, since the option was previously hidden. Users with CRT / PVM / BVM displays with supported 480p Progressive Scan mode will also benefit, since no Wii setting change will be needed for the "Original" 240p mode to be used.

[001 - July 12, 2008]

[2.0.1b8]

• Added: SD slot B options for freezes, sram and loading of roms
• Changed: SMB options no longer displayed in menus when run on a Wii
• Changed: Game auto resumes running after resetting when choosing the "Reset Game" menu option
• Fixed (maybe): Reading of DVDs past the 1.36 GB barrier (Wii only) please test! - svpe

[2.0.1b7]

• Fixed: Zip compressed freezes to memory card could become corrupted as the file size changed - fixed this by deleting the existing file before writing a new one if the file size increased. If the file got smaller or stayed the same the original file is updated, using less of the existing file if the actual file size is smaller. A check is made before deleting the existing freeze file to ensure that there is enough space available for the new file. Note that additional space equivalent to the new file size must be available. If not enough space is available the original freeze is retained and the user is informed of the lack of space.
• Fixed: If option to auto-load freeze was selected, joypad config would not be restored since that is stored in SRAM. Resolved this for now by first loading SRAM if any and then loading the freeze. Obviously having to have both SRAM and freeze is not ideal, but this gets the job done if you have enough space on your memory card, SD card, etc.
• Added prompt when returning to the menu with autosave enabled allowing the user choose whether or not to perform the save. Press A to save or B if you don't wish to save.
• Added optional verification of Gamecube memory card saves. After writing the file it reads it back in and verifies that the written file matches what was to be saved. If it doesn't or if there was a problem opening the file it reports the problem to the user. Set this option in the preferences if desired.
• Added Reset Gamecube/Wii menu item
• Experimental DVD support for reading beyond 1.36 GB barrier on Wii. I have no way to test this, so please report on whether or not it works! Based on svpe's code.

NOTE: due to changes in the settings, this version will reset your emulator options settings, so if you had saved preferences you will need to make your changes to the emulator settings again and save them.

[2.0.1b6a]

• Fixed: Going up a directory when selecting a rom on a DVD wasn't working

[2.0.1b6]
