  • Challenge/hardcore mode (savestates and cheats disabled)

• Refactor so we can play sounds on top of gameplay Change the sound effects mixer (used for UI sounds) to mix on top of main output #17703
  • Copy custom sound effects into the memstick dir
• Sound effect for unlocks and leaderboards submits Achievement Unlocked sound effect, more UI work #17705
• Correctly call do_frame even during fast-forward RetroAchievements: Call rc_client_do_frame from hleEnterVblank #17710
• Cache icon images properly (Save/Load the icon cache to disk if RetroAchievements are enabled. #17709 )
• CSO file support (RetroAchievements CSO support, delay until identified #17699)
• Make it work even when launched from a frontend (RetroAchievements: Try to eliminate possible race conditions on load #17708 )
• HTTPS support, so we can use the standard RA URLs
• Correctly handle HTTP timeout ("When a request times out, the server callback should be called with a NULL
• More UI tweaks
  • Customizable sound effects Custom achievement sound effects #17725
  • Filtering or collapsible sections in achievement viewer Make the achievement lists collapsible on the main achievements screen #17728
  • Improved text formatting in achievement list
  • In leaderboards, show just the range you are in by default. Allow choosing to view top entries. Leaderboard: Choose whether to see top players, or "around me" #17828
  • Allow configuring in which corner for notifications to show
• Disable more things in challenge mode
  • Interactive debugger
  • Remote debugger
• "RAIntegration", for easier development of achievements on Windows?
  • Use the RAInterface library for loading the DLL
  • Alternatively wait for rcheevos to integrate RAIntegration, this is planned
  • Debug setting to allow saving, but not loading, state in challenge mode (only meaningful after RAIntegration is added): RetroAchievements: Add option to allow saving, but not loading, in challenge / hardcore mode. #18425
  • Allow changing mode (softcore etc) in-game

Additional feature requests:

• RANDOMPLAYER1: can i request a feature when achievements that are nearly done can they move up? Like 4/5 monsters are killed they'll be moved at the top of the locked achievements or maybe they'll be moved to almost done category?

I've tried only a few games that support achievements, for example the game the 3rd birthday Region USA & Japan there is no achievement.

Under "Supported Game Files" on the RA website it says you need the "Europe" version of the ISO

Yes only for the European version

it looks like ppsspp needs a team to make game support achievements,

That's not something that PPSSPP can do, that's on the RetroAchievements side of things.

@LunaMoo like you said, some people may use cheats to unlock achievements.

I want to know if my account will be deleted if I use cheats.?

[hrydgard]

@IrfanH495 That's up to Retroachievements policies, not PPSSPP.

Though, I'm thinking of disabling cheats entirely when RetroAchievements is active, and will definitely disable them when challenge/hardcore mode is enabled later.

[IrfanH495]

challenge/hardcore mode it's an interesting feature, but what about the 60fps cheat the hatsune miku game is very difficult to play at 30fps.

[hrydgard]

@IrfanH495 Technically I guess we can whitelist a few cheats like that, although I'm not sure the RetroAchievements project will appreciate that.

I think cheats are allowed on other RetroAchievement implementations when not using Hardcore mode, so you could leave them alone when the user has Hardcore mode disabled (Softcore mode basically). With the exception of fast forwarding, Hardcore mode doesn't allow for any possible convenience features. More specifics can be found here: https://docs.retroachievements.org/FAQ/#what-is-hardcore-mode

To give my two cents about this, the whole point of hardcore mode is for the player to play as closely as possible to what original hardware offered, but now with achievements. I think no cheats should be allowed when using Hardcore mode even if they are improving the experience instead of just giving you infinite items or stuff like that.

In Hatsune Miku for example, in all 3 games the achievement set dev added a 60 FPS patch, if there was a whitlelist of cheats this patch would not even be necessary, but of course that depends on what the RA staff thinks about it

RetroAchievements uses patches to trick the hashing system into thinking the game is a different one entirely (note patches != cheats, we're talking about ips patches and the like), this allows for the bonus sets you can find for plenty of games. If the Dev added that patch, then the user can just patch the iso and the game will be recognized. This has nothing to do with the cheats system.
