@Mr Postman: The roms should work on MAME, some will have some glitches though, make sure you also have the bios somewhere MAME can find it because you will need it to run the games. Not sure if you are familiar with MAME at all, but I'm happy to help you out getting the games to run if you need to.
Problem with making a dumper is the proprietary connector which means you'll need a donor Gamate console to extract the connector from in order to build one. If you have one (a broken one will work) I'm sure Juan or Peter will happily build an adapter for you. Peter will probably see your post here and chime in, but since you are in contact with Juan ask him to join the mailing list and it might be easier to get in contact with Peter that way.
