Same as the FpseCE Official Compatibility List in concept, but very slightly different in execution. This will include the game name, framerate, any noticeable audio/video bugs and the device used to test it.

Hi All...I've been playing Nectaris: Military Madness and it works great on version 0.10.48. Runs at a constant 60fps on the Xperia Play. No graphical glitches whatsoever. Music has a slight intermittent slowdown in some of the cutscenes. This is a sequel to Military Madness on the Turbografx (Nectaris on the PC Engine in Japan).

update: When using fpse's save feature (not the memory card), loading the state will cause the map to be blacked out. It comes back after a fight scene though.

60 fps. No graphical or audio glitches.

Final Fantasy Tactics (NTSC-U) [SCUS-94221] HTC T-Mobile G2
60 fps. No graphical or audio glitches.

Note: I haven't played through the entire game for either, but enough to get past any intro sequences and into actual game play for testing.

I had some time to sit down and try out some games, I've included stock speeds of my HTC Desire and the overclocked frame rates so you can see how well the game frame rate will scale with a higher clock speed. The majority of my games are on their proper discs, I haven't had a chance to make an image out of them yet. I probably should do that soon before I lose them. I'll update my post as I go. Testing was done with a PS3 DualShock3 controller over bluetooth for best results.

I also found that using "#FF8000" for orange was easier to read.

Also want to mention that these disc images are not compressed with PocketISO and consist of either:
.MDF
.IMG/.CCD/.SUB
.BIN/.CUE
.ISO
File formats.
