Hey thanks, Andy. I appreciate that. This rig is being built for an end user who's not mame savvy and I'm trying to keep them from ever needing to leave the hyperspin playpen, if you know what I mean.
I've got the recoil running on 36 v and all the way up because they wanted the max/ closest to arcade levels of recoil. I know from my kids using the guns that they like it much better with the recoil off. Since the client has small kids I'm trying to give them the best of both without having to adjust settings. I feel better knowing its ok to do without messing up the boards. I got submini slider switches from radio shack that can go up near the secondary button. I'll post some pics when I get it done this weekend.
