(I've only tested this with T2)

I first calibrated the joystick/pots within Mame and then tried in T2 itself. It does appear that it is only reading the 1st half of the input. After a bit of messing with a stock joystick I couldn't get any results...so I thought to try a POT 1/2 the value of the joystick pot....50K.

This worked a lot better, however the problem now is that the cross-hair jumps around. I thought this might be due to using a cheap Radio Shack POT, but I don't have the problem in other games like Star Wars. Has anyone posted on the MAME development board? If not, i'll do so and ask.

I've got an original T2 which I've just rebuilt. I'd love to get this working in Mame so I can sell the T2 cabinet. :)

: I have been fooling around trying to build homemade analog guns for games like T2, operation thunderbolt, etc. I think it should be fairly simple to make out of PVC, a toy gun or something and just set it up in MAME like a joystick. The problem I have is the way MAME reads the joysticks in gun games. It only registers movement on the positive side of the axis. That is, it only registers movements to the Left or down. I know you could calibrate the gun to work around it but you would lose the precision of the using the entire axis. Does anyone know a way around this? Am I doing something wrong? Has anyone ever tried this before?

: Thanks
