My "testing session" goes ahead...
- the D-pad commands are partially wrong in Continental Circuit (contcirc.zip), Cyber Tank (cybertnk.zip) and Double Axle (dbaxle.zip)... the vehicle turns left also if you press d-pad right (differently the analog stick works fine);
- Konami Contra/Gryzor (contra.zip), Devastator (devstors.zip) and Devil World (devilw.zip) run very slow (about 7-9 fps), probably the issue is related to the rendering method;
- Dock Man (dockman.zip) doesn't run (FBA crashes);
- in Esp. Ra. De. (esprade.zip) there is a wrong setting, with "START" you select the "player 2" while, obviously, the buttons mapping is dedicated to the "player 1".
PS: Is it possible to add an option to switch the sound output from stereo to mono? It should be useful to give a little fps boost in some games (like Irem M72 games).
