Well I've trying some games with the latest 0.35, games are mostly ripped with pocketiso, speed 300mhz:
Marvel vs Capcom: Works, however there's something strange that it freezes if sound is off, if you turn it on it keeps loading, so for testing ingame sound has to be turn on to get there. On frameskip 1 it's barely playable, 5-7 fps, and any more frameskip gives backgrounds turning to black from time to time. It's a pity since at frameskip 3 would start to be playable imho.
Capcom vs Snk pro: Same as MvsC, similar speed, same issues about backgrounds (this time blue background from time to time), sound off lets the game load though.
Marvel Super Heroes: A bit more playable than those other two, but still too slow to be playable.
Castlevania: SOTN : Improved over previous version but nowhere near playable. Got to dracula chamber and no issues.
Street Fighter Alpha 3 - Still slow, 5-10 fps, not playable for me.
XMan COTA : Freezes at Acclaim screen and stays there forever.
Darkstalkers 3 : This has to be the fastest of all the fighters tested but again not yet to a decent playable level.
Guilty Gear XX: Terribly slow, completely unplayable.
Megaman X4: About 10 fps, barely playable but looking good
R-type : Freezes at loading, I've heard it works around but my copy doesn't.
Tekken 3 : Freezes at loading game screen.
Secret of Mana: Works very decently but still not playable. Probably the one that works best of all tested.
Strider 2: Works, slow, again about 5-10 fps, couldn't jump ingame, but it looks great. Suffered some issues with backgrounds not being refreshed properly.
Summary: Some 2d games give background issues, frameskip is not balanced, 1 gives a nice boost while 2 and + gives massive missed frames and time warps. There's a strange issues with sound on Marvel vs Capcom. Haven't tested the memory cards but the games found them so they seem to work even though they found nothing to load. Overall, it's awesome to see some of those games working even on their current state, but there's a long way for them to be playable still, but keep up the good work
Suggestions: The fps i'm giving are my opinion from what I saw not the emu data given since I could only see those when changing frameskip with volume. I wish there was some kind of switch to turn fps visible always. Since these are early versions I would suggest to let fps always on to assess better the speeds.
There's almost no advantage on turning sound off, which for me this is quite strange, I was hoping that we could get much better performance without sound, but that's not the case.
That's it, I have LOTS of psx games to test but right now I will wait for a better version to make a massive test to see what really works and what doesn't. Besides I don't have the power supply so batteries are suffering badly with all the testing :blink:
