When I set offscreen_reload to '1' in the mame.ini, the B button of my lightgun works as reload for games like Lethal Enforcers (that needs to shoot offscreen to reload).
However, I cant leave it this way permanently... if I do, other games that dont use offscreen-reload and have a different function for button B... the offscreen_reload option seems to make button B function the same as Button A (mouse 0) when I set things up in the game config.
Is there a way to set things up so that offscreen_reload is configured on a game-by-game basis?
