I think you need to select the JIT option on theA500mini otherwise you get lots of crashes when moving between screens.
Did that do the Trick selecting jit mode?
It does for the most part, so you can play level one on the mini. But a few seconds into the boss fight it crashes and the JIT doesn't stop that.
Please try the new Build. we test on Winuae and no crash.
It still crashes a few seconds into the first boss fight. It goes to a grey screen with 'Holy Warrior failed returncode 20' at the bottom of the screen
