About
-----
FastDoom is a Doom port for DOS, based on PCDoom by @nukeykt. The goal of
this port is to make it as fast as posible for 386/486 personal computers
https://github.com/viti95/FastDoom
Motivation
----------
Vanilla Doom required a powerful machine when it was released in 1993.
To run it properly, a 486 was mandatory, with at least 8 MB of RAM and a
Vesa Local Bus video card. A machine with those specs in 1993 was
pretty damn expensive. The game itself run pretty slow on 386 PCs
even at low detail and small screen size. I started this project in April
2020, after suffering the COVID-19 disease, nearly 27 years after release
of Doom. I was very sick, and after the recovery I decided that somebody
had to make Doom run well on all 386 personal computers, and make their
owners proud of their machines.
Minimum requirements
--------------------
CPU: 386SX at 16 MHz
RAM: 4 MB (the executable runs even with less RAM, but it's
possible to see random crashes due to low RAM)
Video card: Any ISA 8-bit Hercules, CGA, EGA or VGA video card. For cool
graphics a fast VGA video card is recommended. Also MDA,
Plantronics Colorplus, Sigma Color 400 and Hercules InColor
cards are supported
Controls: Keyboard (mouse recommended)
Supported IWADs
---------------
FastDoom guarantees support for the following IWADs, provided the correct
file names and specified versions are used:
DOOM Registered (3 episodes) -> DOOM.WAD (v1.9, 11159840 bytes)
DOOM Shareware (1 episode) -> DOOM1.WAD (v1.9, 4196020 bytes)
Ultimate DOOM (4 episodes) -> DOOMU.WAD (v1.9, 12408292 bytes)
DOOM II -> DOOM2.WAD (v1.9, 14604584 bytes)
Final DOOM The Plutonia Experiment -> PLUTONIA.WAD (v1.9, 17420824
or 18240172 bytes)
Final DOOM TNT Evilution -> TNT.WAD (v1.9, 18195736 or 18654796 bytes)
FreeDoom Phase 1 -> FREEDM1.WAD (experimental support)
FreeDoom Phase 2 -> FREEDM2.WAD (experimental support)
Any other version used may cause issues and not function correctly.
Remember to rename the IWADs according to your needs.
Supported hardware
------------------
CPU: Any x86 processor that supports 32 bit i386 instruction set
Video cards: MDA, Hercules, CGA, EGA, VGA, Plantronics ColorPlus
Sigma Color 400, Hercules InColor, SVGA (VBE)
Sound cards: Sound Blaster, PC Speaker, Disney Sound Source,
Gravis Ultrasound, Pro Audio Spectrum, COVOX LPT DAC,
Creative Music System, Tandy 3-voice, OPL2LPT,
OPL3LPT, Ensoniq Soundscape, Adlib
Music cards: Sound Blaster (OPL2 and OPL3), Adlib, MIDI, Gravis Ultrasound
Sound Blaster AWE32, OPL2LPT, OPL3LPT, AudioCD (MSCDEX),
PCM music (through sound card), Ensoniq Soundscape
Serial MIDI, DreamBlaster S2P, Roland MT-32,
Roland SC-55, Yamaha MU80, Yamaha TG300

Limitations / Known bugs
------------------------
* Gravis UltraSound cards require IRQ to be 7 or less, otherwise those
cards won't work. This is a limitation of the Apogee Sound System.
* Some executables will show snow issues on IBM CGA cards even if '-snow'
command line parameter is used. This is due to technical limitations.
* Showing FPS on a debug card can show weird values if a Sound Blaster
card is used, and can cause sound issues. This is due to port 0x80
being also used for DMA transfers.
* No sound with SBEMU: FastDoom requires VCPI to be disabled before
running the game. Run 'jemmex.exe novcpi' before launching FastDoom.
* Older VGA cards may exhibit snow issues during palette changes.
These cards need to wait for VSYNC before changing the palette.
Use the '-fixDAC' command line option to fix this.
* Some newer VGA cards may display a distorted image in 80x50 text
mode. This is caused by a different video page size on newer cards
compared to older ones. Use the '-pagefix' option to fix this.
* VBE2 Direct modes (fdm***d.exe and fdoomvbd.exe) do not support 15-bit,
16-bit, 24-bit, or 32-bit video modes.
PCM music format
----------------
PCM music format is unsigned 8-bit PCM, and supports 11025, 22050 or
44100 Hz frequencies.
Use SOX to convert files to RAW format, for example:
sox D_E1M1.ogg -r 44100 -e unsigned -b 8 -c 1 MUS_1.RAW
Folders used for music are these:
* Doom: \MUSIC\DOOM1\MUS_*.RAW
* Doom2: \MUSIC\DOOM2\MUS_*.RAW
* TNT: \MUSIC\TNT\MUS_*.RAW
* Plutonia: \MUSIC\PLUTONIA\MUS_*.RAW
