Quoted from Compy:
Agreed on all points! So the CGC menu trick is a bit simple. Basically the emulator receives all of the switch matrix events on the game, you then intercept the coin button switch events, stop the CPU clock, overlay the SDL display and redirect all the switch events to the custom menu.
Plus the DMD coloration scheme is likely different as to not infringe upon any of Randy's IP, so it could likely use a bit of tweaking.
I really don't see them getting away from emulation for the remakes though as they just don't have the software talent in house anymore to do it... I hope I'm wrong though! Happy to eat crow on this one.
Oh, I don't see it happening either, but that is what I would like to see.
I would also like to see them move from their own hardware to a P3-ROC, but that definitely won't happen!
A benefit of the P3-ROC would be that Eric's P-ROC code could be relatively easily converted to work with the P3-ROC. That would allow remake owners to run either CGC's or Eric's code, but now I am just dreaming...
