Update:
New adapter works perfectly, but my ROM converter that switches Genesis ROMs to BIN format refuses to do it correctly.
Genesis ROMs that are playable on a PC have their header data modified and this has to be removed in order to burn them properly. I will either have to do it manually or find a new converter.

The way I figured out that my adapter works (this time) is that I used it to dump an official Clue game and then burn it to an EPROM. Clue loaded up no problem, but I did not have to convert the ROM like the games I do not own and have to download.
