While I was a big gamer on 8-bit machines back in the early 80s, joysticks always hurt my hands after playing a while. When I got my first console, a Nintendo Entertainment System, I realized how nice it was to use a D-Pad for extended game sessions. Here are two ways to use a D-Pad on the Commodore 64 (and other machines) which makes playing much more ergonomic.
NOTE: PadSwitcher64 control software now works perfectly both NTSC and PAL machines, thanks to the author for fixing that issue!
