My Example of Custom Arcade Style Joystick - The problems.

The main problem was that on the left side of my joystick I have hacked PSX pad and KE24 connected, so to play with the playstation, I had to play with the PSX and the KE24 power on. So with my computer power on.
A good solution that Andy from Arcade Solutions gives to me, is to put a switch to share a printer for PC between the controls and the 2 encoders.
Yes, it's great ! Now, I can choose to play PC or PSX, without any conflicts. And, I can play PSX on side one, and at the same time, I can play PC, on the right side. ;-)
