I'd love to have a go dumping the HMG-7900/SD-200 stuff. Not sure if SlyDC has all carts or if you have something unique, but I could borrow him some (he lives an hour from me).
ssj: you have a list of your carts?
I have all released carts (English versions) except SD-204 for which I only have the French one. Also have the French/Hanimex releases of others not exactly sure which ones from memory, but I'm guessing there won't be a difference between them.
I think SlyDC also has a full set so would probably be easier for you to get them from him since you live so close to each other. If he is willing to lend them of course. If not let me know.
