Speedball 2 seems to go into and out of pause mode everytime the player tries to move with remapped keys. My guess is that this happens because SB2 pauses from all the alphabet keys in keyboard by design, according to the game manual, and the joystick mode registers keypresses on the keyboard as both joystick and keyboard inputs simultaneously. Bad luck... Parasol Stars and Paradroid'90 work fine, so it's only this type of special case that causes problems. For the record I'm using scandic remapped version of UAE4ALL.
