2 PSX emu's for me to test? I'm going to be spoilt! I didn't get my gp2x for PSX emulation, and never actually expected to see games such as FF7, Abes oddesy and the likes run as fast as they currently can.
[edit]
More and more tests! All ran at Clock speed 280Mhz, Ram timings on, with no sound or interlace unless otherwise stated. Test 3 build.
Air Combat : (PSX CPU 100% Cycle 4.0 FS 0/1) Frame skipping did not work on this game (models flashed, menus missing) but it ran so well once in game it did not require frame skip! The emulator was reporting 61 REAL FPS, and it looked that way to the eye also. I decided to try this with sound on, in menus, it was playing slower than it should, but once in game it was surprisingly accurate. I'm shocked!
Bishi Bashi 2 : (PSX CPU 70% Cycle 4.0 FS 0/1) Another practically full speed title, although this time its not so surprising. I again tried with sound on, and although it sounded mainly OK, it lagged at times, causing the GP2X to sound like it was screaming for me to stop
Frame skip also did not work with this title, but again, there was not much need for it.
Bomber man : (PSX CPU 100% Cycle 4.0 FS 1/2) Ran at about half speed (30FPS) regardless of settings. Increasing PSX cycle reported more FPS to the counter, but visually it stayed slow. Frame skip worked with this title, but again, seemed to offer little benefit.
Castlevania - Symphony of the Night : (PSX CPU 100% Cycle 1.2 FS 1/2) VS and fps were stable at the above settings at 38. It was skipping frames, and ran a little slow, but seemed OK without sound. I have never played this title on an actual PSX, so maybe you just are really supposed to move that slow? I should do a few videos, but my camera is AFK
Pocket Fighter : Blank screen, tried several Clock and Cycle settings, and although something seems to be happening (whatever is happening is happening at 43FPS), the screen remains blank. Maybe a bios issue, will try a few later.
Resident Evil Directors Cut : (PSX CPU 80% Cycle 4.0 FS 0/1) Speech does not work, but sound is OK, just a little bit slow at times. Mainly the game play is much faster than any other release AFAIK, but not as fast as the frame rate counter was reporting. After a couple of cut scenes my characters head became invisible! In areas with lots of chars the frame rate drops badly, and although frame skipping worked, it did not seem to offer any improvement. More playable than before, but in areas with lots of actors, eugh.
Tekken 3 : All I get is garbled graphics, and then the emulator freezes, could be my dump, will obtain another and try again.
Tobal 2 : (PSX Clock 40% Cycle 2.0 FS 0/1) Runs too slow to be considered playable, but it is emulated accurately. Game runs nowhere near reported FPS and neither frame skip or interlace work with this title. Tested it in both Tournament and Quest mode.
----
One thing I have noticed, is that frame skip does not work for a lot of PSX titles, so maybe it should be disabled by default? Its current default is 1/2, and this setting seems to cause a lot of issues like flashing graphics and textures, or blank screens. If you are experiencing any of these with a game, turn off frame skip!
