Okay so now i see what was the issue. "UP" doesn't work when mouse 1351 is connected to port 1. Problem solved, but consider to fix that in next patch.
Hmm.. 1351 mouse uses potX/potY, and they are "common" for port1 and port2. The game uses potX/Y for additional Fire on Joystick port 2. (Fire 2 = Jump/UP)
Is it a game problem or more hardware problem..
Maybe you can't have a mouse plugged in and use the program (driver) for the Joystick with three Fire buttons at the same time.
Maybe the Joyride program from CSDB is able to test this.
