Yeah, I actually used r202 a couple months ago when I heard that... I'll try to use SCPH7502 if I can, so you are saying that maybe some bugs will get out if I use the newer BIOS?
Anyways, got some new tests. All were done from the past couple hours on USB, my Slim SCPH75001 with the SCPH1001 PS1 BIOS (for now at least):
Notes: Opening FMV with helicopter doesn't work but you can skip through it. No talking from any of the characters. Runs at almost 60fps in some locations but less when more characters are on screen. Few textures in some rooms are glitched.
SLUS_006.62 - Disc 1; SLUS_006.68 - Disc 2
Notes: No sound in FMVs i.e. car noises but music still works. Maintains a constant 60fps with no slowdowns. Very playable. Needs SPU IQR enabled for proper sound.
Parasite Eve 2
SLUS_010.42 - Disc 1; SLUS_010.55 - Disc 2
Notes: Hangs on Squaresoft image.
Notes: No sound in FMVs. Transparent white boxes around characters and trees. The boxes are gone when in the dark/Otherworld/Hell. Lags heavily when various things are happening on screen, like snowing or the flashlight in general. Not very playable in some spots, but playable in others.
Toy Story Racer
Notes: Very bad graphical glitches, such as the same one in Pong. Fps drops to about half speed. Not very playable.
Final Fantasy VII
SCUS_941.63 - Disc 1; SCUS_941.64 - Disc 2; SCUS_941.65 - Disc 3
Notes: Some flickering at screen border. No sound at FMVs i.e. Aeris walking but music still works. FMVs also get out of sync with audio. No battle swirl, fps drops some when the battle swirl is supposed to be displayed. Very playable, maintains a constant 60fps. SPU IQR required for proper sound.
Final Fantasy VIII
SLUS_008.92 - Disc 1; SLUS_009.08 - Disc 2; SLUS_009.09 - Disc 3; SLUS_009.10 - Disc 4
Notes: FMVs have some half-second stutters, music glitched up at last half of opening FMV. Ingame works very nice and maintains a good amount fps. FPS drops more when a lot of characters are on screen or on the world map. Very playable.
Have fun putting this on the list.
I'm no noob, I just don't post much :P
