C-64 DTV modifications

[moparram]

I'm working on my NTSC DTV and added a ps/2 port and a joystick port. For some reason, the joystick won't move the on-screen character to the right. All other functions work. Some keys I press on the keyboard won't work either. I also added a power supply to the unit, a 6V wall transformer. Any thoughts would be appreciated.

I'm not sure what to suggest other than checking out the DTVHacking forum. You should post about this problem there on the off chance that someone there has experienced a similar problem. I would also poke through the older messages. It has been a few years since the peak of DTV hacking and the older messages tend to lean towards these types of problems.
