Thanks hap! Without your and Seans work this would not have been possible
Btw, JD sent me one older game, Fire, which I believe has as SM5A inside. I haven't tried dumping it yet but looking at the Mickey Mouse ROM which is for the SM5A, the filesize is smaller than the ROMs for the SM510 and SM511/SM512 so I think the dump process needs to be adjusted to also work for the SM5A. Does anyone have a datasheet for the SM5A that explains the memory layout and such?
