Haha, soooooo true, there are so many options and possibilities to consider, it can be a little overwhelming.
But I feel like I have to make a decision and say: now it's good enough, otherwise I'll never stop tweaking and having 4 hour-per-night sleep (I... just... can't... stop.. :P). I'm glad it's all working, except for a few MAME games.
The endresult is breathtaking really, best 20 dollars I ever spend :D.
