Does anyone know how to put the Genesis/Megradrive in Master System Compatibility mode?
The power base converter made that possible for the original hardware by connecting some pins to GND, or VCC.
However, I guess the core itself has to do something to react on this configuration also, e.g. to load the rom code into the Z80 address space etc.
Do I need to change the addressing somehow, disable the m68k etc.
Please reply to this if you have more information on how the Genesis/Megadrive was set up in order to play Master System games?
Also if anyone knows if there is a Genesis/Megadrive game that uses the Master System video mode, please tell me?
If I would have such game, I could at least start by testing the Master System video of of the FPGAGEN VDP and see if it's working correctly.
If no such game exists, maybe a possibility would be to program a small demo Genesis rom using the Master System Video mode?
I know that there are some tools on the net for programming new Genesis/Megadrive games.
The reason for asking these questions is that I want to enable the possibility to play Master System Games in the FPGAGEN core.
It would be easier to maintain one core FPGAGEN instead of having a different core for Master System. Which no one seems to attend to anymore...
Happy New Year 2018
