Sorry I didn't get around to this earlier...(posted 9289 days ago)I really have no idea what exactly causes the JOYSTICK ERROR in Guerilla War. It might be like QT said, where if you spin it too fast, it crashes... but I'm thinking that it has something to do with how much spinning you do of the rotary total. For what it's worth, I always lower the analog sensitivity to 8% or so.
Maybe the MAME version has something to do with it, I dunno... and I have no idea how I managed to get 100k without it crashing, I was a bit stunned by that myself. (not by the score, but by the fact that there were no crashes)
Boy, some help I am.
