I was in the process of dumping all my cartridges that are either pirate variants or undumped unlicensed games. I ran into a particular snag with one unlicensed Mega Drive cart that I'm unsure how to get around.
Currently I've got a 16m Multi-Game Hunter and a 24m Double Pro Fighter trying to dump a Mega Drive game. The cart plays fine on my machine without any problems. When connected to either of these copiers it does not even show up, both report a game not inserted in the cart slot.
I've dug around a bit trying to find some more information, possibly someone else that has run into the same situation. All I've managed to find is a guy that was trying to dump a Sonic 3 cart with a DPF, he found that by masking over a few pins on the right hand side of the cart connector he got the game to show up and dump properly.
Any ideas? I'm sure there's some sort of copy protection in place as most of these original run unlicensed games have, but all I've ran into at least showed up when connected to a copier.
