I soon found out that they're not guaranteed to work neither. Whilst I endevour to acquire the best ISO images for PCSX rearmed.

Then during lanuch command you can choose 'old version', and you can still keep the 'original new version'. Lr-pcsx-oldversion = '/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-pcsx-oldversion/libretro.so -config /opt/retropie/configs/psx/retroarch.cfg %ROM%' or edit emulators.cfg and add a text line : put emulators.cfg inside /opt/retropie/configs/psx to replace the old one.Then put ' libretro.so' inside /opt/retropie/libretrocores/lr-pcsx-oldversion Make a folder called 'lr-pcsx-oldversion' Tekken 3 lag in new version but smooth in old version. I have the working old version binary file but I don't know if I can put it for test, it still show 1.3.6 r22, but the file size is different. If you use old version, or RecalBox's version ( 1.3.4 r22 ), it will pass the memory card check and start game. Play 'Zanac x Zanac', after choose Zanac Neo, at memory card check screen, it will freeze there. RetroPie 4.1 update to latest lr-PCSX-ReARMed 1.3.6 r22, The Dreamcast version of this game runs very well. Evil Dead: Hail to the King will start and show the intro but once you get in the game it has no sound and the screen looks off.Loaded & Reloaded will run and everything looks good except non of my buttons on my controller do anything so I can't start a game.I can't get any Japanese PSX games to work but that could be a BIOS issue or something I'm not doing correctly.I think a time or two it froze on me when using RetroPie 4.0rc. Tekken 3 ran surprisingly well for me and I played it for quite a lot without much trouble.

Tekken 2.okay so I've tried 2 different ROMs from 2 different sites and they both act like I'm playing the arcade version with 'Insert Coin' only I can't figure out how to bind a key to that so I can play it! It runs fine other than that 'small detail'.Metal Gear Solid played well but I only played it for about 15 minutes.Spyro - Year Of The Dragon ran okay with some more graphics flaws.Gran Turismo 2 (Arcade Mode) v1.1 plays pretty well with some very small graphics flaws that really didn't bother me when playing.Driver on RetroPie 3.7 and it seamed to work okay except I never finished the first mission & I just free roamed for awhile.Here's what I've tried on my Raspberry Pi 3:
