Yep thanks did that. But this core doesn't see the Bluetooth controllers sadly. Opened an issue in the sub git
I don't know much about arcade emulation but anyone may know if my problem is Roms related and not a RetroArch problem ? My mame 2003 loads all my like 10 games fine except Windjammers. I'm sure it's a mame ROM, the contents inside the archive are .Bin. I tried different versions but MAME either DSI (when it's not the proper format I guess) or acts as if the archive were empty :\
Is windjammers known to be difficult to emulate ?
