This repository originally corresponded to ps2 port of SDL DOOM made by @lukaszdk

However, he personally linked in his website to another version by Jason Yu, wich has audio support and other toys (eg: USB support)

the new code comes from update 2 at the webside of lukaszdk

I have made a few tweaks to it:

• Usage of FILEXIO and IOMANX modules: fixes a very weird bug I had where doom would fail to obtain all the lumps from WAD files (each wad had it's last 3 lumps corrupt/null/mixed with lumps from begining of wad)
• Support for arcade PS2: it should run on NAMCO System246/System256 as well as Konami Python1. the design of the arcade version was made mimicking the file layout of original System246 games, so you could make a DOOM dongle :D
• compiled with PS2DEV v1.0: wich brings up 15 years of PS2SDK enhancements while also allowing CI with github actions
• reboot the I/O processor on boot: more stability, less hangs due to IRX modules from the program that ran the game staying when they should not
• I_Error function will no longer exit the program into OSDSYS, instead, error is printed on screen and thread sleeps

get them yourself

to compile the source code, you need PS2DEV v1.0 docker image (ps2dev/ps2dev:v1.0)

as well as a modified version of PS2 SDL I made, to get that SDL run make arcade-sdl

for compiling PS2DOOM do

make clean all -C src

for compiling PS2DOOM for Arcade PS2 do

make clean all -C src ARCADE=1

(binary will be called ACDOOM instead of DOOM to avoid overlap with retail targeted binaries)

the boot.bin file provided in the release package for arcade doom is an already encrypted proverb bootloader, it expects the game ELF to be located at mc0:ACDOOM. use it if you prefer Arcade DOOM to be a standalone dongle mimicking the layout of original games
