Was the stick a restricted 8-way or was it just a 4-way turned on a 45 degree angle like Q-bert? How do you think it would play with Tron?
Sorry for the late reply. . .
I'm just making some educated guesses based on playing the game a few times in the arcades. The stick was not on a 45-degree angle. The way the game was set up, there was no reason to keep you from going forward and left at the same time, so I would expect 8-way rather than 4-way operation. Based on it's age, I would think leaf switches are more likely, but that's just a guess.
As far as tron, I would expect it to work for the 8-way portions of the game and maybe to have problems on the 4-way light cycle parts. You could maybe modify the actuator or you could use Oscar's restrictor plates for this part. Just guessing here also, though.
FWIW!!!
