+1 for Pascal But let us not forget why we're (partially) here for : to learn. I'm in for fun with Genesis, but it was also to learn 68k programming. So if you want to learn .NET, and by the way, enhance KMod, it's your will, it's your life. Noone could (should) prevent you to do this. Do what you w...
