RICKR , thanks for the offer, I may take you up on that once I decide whether I ditch this 128 and buy the SD or simply make do with got. I would like MULE and Bounty Bob on a multi cart so it seems the SD is the way to go.
This all started after trying to load Atlantis and Demon Attack only to lose everything I had. A couple of the guys on the 5200 HSC were nice enough to link and load me up with game files, but for some reason we can only get one of the mass binary files to load , and that one is out of alphabetical order.
We then tried to combine 2-3 sets of binary files with the entire 5200 library with protos, hacks, and also a bunch of conversions for 5200 , tossing out any of the duplicates and that wouldn't load either. tried them all separately and no go either.
We've gone round and round checking this and that and there is no reason they should not load to the cart. My original disc had no drivers on it, we received a replacement disc, but no answers to any emails afterwards asking what other issue we might be having.
Heck this isn't rocket science.
