Sorry if this has already been explained but I was wondering just how this works. I've heard of some hacks that get Star Ocean and SFA2 decompressed and working on real hardware as long as you can provide 12MB of ROM and I never understood how any of that was possible. My understanding was the system hardware itself allows 2MB slow rom on mode 20 and 4MB of fast rom on mode 21, and a mix of high and slow speed on mode 25 with 7.85MB available.
So if 7.85MB is the limit as designed without additional hardware, how do some of these flash cartridges provide 12MB and run games like SO? Isn't the system stuck with banks 40-80 and c0-ff? Or does it actually read flat across banks 00-80(8MB) and then across c0-00(4MB) in map mode 25?
