I guess it would be nice to have a choice.
I'm currently doing a C64 DVD and I'm going to try and have a choice between CCS / Vice / etc. and then link to any reg files for the settings.
I must admit with SNES9X I have a massive problem with the sound (Sound Blaster Audigy 2) and this does crash a few games. It's nothing major but can be a pain now and again.
DVD's almost done now after that last file.
Superb job in my opinion mate.
