I still don't have a Supercharger of my own, so comments >please on whether this loads and/or runs on the real thing :-) (I've only >run this on PCAE) I have tried it on my Supercharger and all I got was a black screen. It seems, that you have the writing enabled on load time and that the code starts at $F000. That might not work, since accessing addresses in the first ROM page with writing turned on will initialize writes instead of running the code. You could try loading the game with writing disabled and only turn it on, when you are not accessing anything in the first 256 bytes. Also you don't have the SC-ROM powered up at load time. I havn't looked at your code, but you need to turn that on later, when you want to load something. The emulator might not require that. Another thing with SC-writes, that the emulators don't do right, are indexed writes over page boundaries. On the emulators nothing happens, when you do an indexed write, that goes over a page boundary, but on the real thing the write would wrap around and happen to the beginning of the lower page. That could crash your game, if it hits important code or data. BTW it would be nice, if you could send every load in a seperate file with your next release, since it is easier to merge the files together for use with the emulator, than it is to seperate one big file for use with makewav. At least under DOS it is.
