@ SuperDan : add info, thanks man. What did you test NTSC or PAL copy GDI ? Rinnegatamante pictures say ~60% framerate (intensive scenes and as low as 10-15 fps), so unplayable. But the Beta copy I had tested for 5 minutes was not so bad, but I dont know the game and so dont know the debug menu, it stops mostly.
BTW: here the flycast-vita Compatibility List from rinnegatamante :
https://newflycast.rinnegatamante.it/
Everything that was tested even with low framerate, the gameplay was mostly full smooth and mostly no texture errors.
Testing :
Name : Shenmue
Format : GDI
Region : ?
Notes from SuperDan : Shenmue 1 work OK lots of texture mashing.. But the frames seem to be steady for the most part much worse on the original Flycast. you can see the texture mashing straight away on my Shenmue it's not terrible but you can help but notice it... The list from Rinnegatamante say :
https://github.com/Rinnegatamante/flycast-vita-compatibility-list/issues/28 Shenmue (PAL) Framerate is very inconsistent, can even get to fullspeed in less intensive scenes and as low as 10-15 fps in intensive ones.
Ryuzaki face is garbled as well as his jacket and those glitches are unfixable (It would require Per-Pixel sorting which is too intensive for Vita and would require GL4).
Name : Biohazard - Code Veronica - Kanzenban (JP)(Disc 1)
Format : GDI
Region : NTSC J
Notes : I would say its not playable, the framerate is good in small rooms without enemys, but with enemys it drops a lot down. The same problem like Carrier. So it would be playable. rinnegatamante list say its good playable, but his list also say
https://github.com/Rinnegatamante/flycast-vita-compatibility-list/issues/147 : ''Gameplay - (13-30fps depending on how many character models and effects are on screen, in the beginning it's raining but after it stops performance increases and many indoor areas run at fullspeed very playable and enjoyable) '' . The game have to play it from beginning to the end, later there are winter snow maps. raining was good for me, but so bigger the outside area so more down the framerate. All in one, very good, but need +10% or 20% more framerate. The Settings Used from rinne list, I come up with the same but different video settings. Biohazard 3 Japan is so far the best Resident Evil game working with this emulator, also a highlight and I will play it the next days from start to the end.
Name : Biohazard 2 - Value Plus (Disc 1)(JP)[XIAOPANG]
Format : cdi
Region : NTSC J
Notes : Stop in the beginning, unplayable. rinnegatamante dont have it in the list. Anyway, I have the original discs and its the only japan import that make trouble on my PAL original dreamcast system. I need a special import boot disc to play it on my PAL system. So I think its just the japan copy that the emulator dont like, maybe PAL or NTSC US will work, but noone had test it so far. So PAL copy test later.
Name : San Francisco RUSH 2049 (US)[ECHELON]
Format : cdi
Region : NTSC US
Notes : In first try it dont work. In second try it dont work and say I need BIOS files (I still have not copy BIOS files), I had wait and the game was starting ! On the normal way the ECHELON release need UTOPIA boot disc, maybe thats the reason, but I dont have Bios files copyed. Framerate between 50% and 70%, rarity 90%, just to slow, no differences in framerate between driving fast or stoping, it depends on the free area how big it is. Main menu is 100%. Testing only first track. Change the camera view to first view give me ~80 to 90%, on this way its not so bad and a little bit playable ! Good Job ! Testing Track 2, DEACTIVATE IN-GAME Sound, was give me more framerate sometimes up to 100%, but also drops down to 80%. So its get better. Tested only 1 car, no tournament.
Name : The.House.of.the.Dead.2.(E)-NBS
Format : cdi
Region : PAL
Notes : After create save file, error. rinnegatamante list say good playable, but maybe they have try GDI instead of cdi ? Test later again.
