I'm working on a little Sega CD backup RAM cart that features a flash memory that will allow one to manage the memory on the cart. When a switch is selected, the cart will boot to that flash memory. The flash memory contains some utilities to manage the RAM and use your Sega CD's hardware. The Sega CD has this convenient feature called Mode 1, which lets code run from a regular Mega Drive cartridge, but make use of the Sega CD's additional hardware. To really be able to access the Sega CD hardware, one needs to initialize the hardware and load the BIOS. How would I go about doing this? The documentation isn't very specific and only lists steps to take. The only other software that I know of that uses the Sega CD in Mode 1 is Flux, a music visualizer. I've attempted to disassemble parts of it, but without much success so I still haven't been able to find the code to do this. Any help would be greatly appreciated!
