RAM cartridge is not initialized.
Use options screen to initialize
I have the usa SegaCD bios, so I don't think it's a bios problem. I also tried it on Kega and on NeoGenesis(Gens port to the XBox), and it's the same problem.
Currect me if I'm wrong, but that option screen that the game is talking about is accessible from the SegaCD bios. So my question is:
How can I access the bios screen via the emulator?
Or how can I initialize the RAM cartridge from the emulators menu?
