Title: GX4000 weird problem, controllers interfered with each other
Post by: Davor Vitief on 19:24, 12 May 21
As the topic says when i play any game if/while both players hold button 1 or 2 simultaneously each control pad moves both characters  ??? . I have tried with a controller and a JY3 and different cartridges leading to the same result, any help is welcome, thank you.

There are diodes behind the joystick ports to stop this, probably one of them has failed.
