After trying alot of games, it seems that even the 'bugs' from snezzids was transfered over.
To be honest, I prefer the previous version with his engine. Sure, most games run at perfect speed with a tweak here and there. But there's too much random freezes for the speed to actually compensate it.
Some examples from the tests I did today:
Castlevania 4 has like 20% chance of freezing when entering a new stage
Sensible soccer froze at the menu
SMB all stars froze at the start of the first castle (might be a % chance as well, but didn't bother to play through there again as I didn't save)
Zombies ate my neighbors isn't running at all now
The old version pretty much was 'you get what you see'. The speed wasn't perfect, but when a game worked.. it worked. No freezings etc. Just the common graphic errors and layers.
So im gonna stick with the previous version till this snezzids engine gets properly polished.
Still glad to see some progress and hopefully bubble will pick up interest in the emulator again now that he has an indirect co worker by his side
