I saw that the pi3 got DC support and I decided to try it out. So far I've only been able to get one game to run, despite the compatibility sheet saying that the ones I'm trying should also be working (albeit slow). That game is marvel vs capuchin capcom 2. The read me file says the supported file formats must be either in gdi or cdi format (mvsc2 is in cdi). I've tried both the cdi and gdi format for some games and I still get nothing. In fact after launching the game, it goes to a black screen and there is no way to exit except by unplugging the pi.
What are some things I need to be aware of? Do only certain types of rips work (IE those that are self booting)? Do gdi files need to all be named the same or kept in a separate folder for each game?
