I went to play Silpheed today (on ROM03, ZIP GSX) and noticed that i
could not go down the screen using my CH Mach 3 Joystick. I thought
that maybe my calibration was out so ran the basic program to
calibrate only to find that everthing was perfect. I ran couple of
other games and joystick ran fine. I then used a spare joystick i have
which is a Kraft one and everything worked ok. So there seems to be an
issue with my CH March 3 and Silpheed...which seems odd as it seems to
work fine with every other game I have. Any ideas...or is it just one
of those things..?

Cheers
Andrew
