I doubt it as gpengine has not been updated in ages. The emulator came out and was very well done but since the initial release there has been little news about it. There was an updated version shown at the gp32 meet up with rf support but that was never publicly released. Since then there has been no news of progress on it so I would assume that black the author has droped out of the scene. Unless he has been secretly working on somthing amazing which I hope is the case but I would not hold my breath for an update.Are there plans to bring CD/Supergrafx support to this emulator?
I mean, is CD support even technically feasible? Some of the best PCengine games are CD only
