Ok gngeopi was the way to go! Although some vsync issues persist that is something that can be looked at.

What surprises me more though (and this goes for FBA too) is that b4 doesn’t remap the controls “logically” on my ps3 wired joypad.

Coin used to be select and start used to be start but now they are L2 and R2 (which I could live with) but also it uses the analog stick instead of the dpad and some buttons do not seem mapped at all.

Where to begin to fix this or am I missing something?

It seemed to work fine in b3.
