Many thanks for the information, yet another addition to my must-buy list

Xian Xi, was just wondering if I could use some of your expertise with regard to the following two questions:
- regarding the hard dipswitches on the MV-1FZ motherboard - initially I will not have the Unibios so what should I set the switches to to have all default options + free play?
- regarding 138-in-1 vs 161-in-1? I would be getting this for a supergun + MV-1FZ setup, so the additional Jamma fingerboard would not be the main concern. Are there any differences in terms of gameplay quality (bugs, slowdown, etc.) between these two compilations? I guess the 138 has more original games and also the ability to hide the worthless hacks but is slightly more expensive... would you say its worth it, or shall I just go the easy route and get a 161 in 1?
