Re: Continue Monon Color development?

问候!

The problem with the Monon Color is that its main CPU has an embedded ROM inside of it, which handles the initial boot-up sequence. This ROM could possibly do anything, and without knowing what it is that the embedded code does, it is almost impossible to guess how the cartridge code should be booted.

The best thing that can be done right now is to try to figure out a way to "trojan" the contents of the AX208's internal ROM, so that it can be emulated fully.

The only alternative would be to have a Monon Color and at least one cartridge sent to someone who has a logic analyzer, who can then figure out what the boot ROM accesses in the cartridge ROM in order to boot the games themselves.
