What do I need to test my programs on a GameBoy ?
Well you need a C3 cart, C3 programmer, and a power supply. The programmer will plug into a parallel port on an IBM-PC or compatible if clearances allow. If clearances don’t allow, then you need a DB-25 male-to-female cable. I don’t currently offer these cables but they should be easy to locate wherever modems are sold. The length is not important because the software can be slowed down to accomodate with the -w option. If you wish to plug the C3 programmer directly into the parallel port connector (instead of using a cable) then you will need to remove the cable mount studs on the C3 progammer connector. These will easily unscrew with pliers or a small wrench.
