Hi. I've been lurking around for a couple of weeks and I finally decided to bite the bullet and build my own MAME cab

I've got a couple of questions. Sorry if they have been asked a jillion times before the search function wasn't working for me.
1) I'd like to do the LED buttons and integrate them into the MaLa front end. From what I can tell there are two products I can use. The keyWiz and the Ultimarc product. I'm leaning toward the keywiz but I'm having a hard time figuring out if the LED are integrated into the encoder or will I need to get a separate encoder module. The ultimarc appears to be a separate module.
2) Joysticks- My wife is a Mrs Pacman fiend and will be most disappointing if I can't recreate the true pac-man feel. So I figure a dedicated four way is a must. What is the best way to get the pac-man feel (I can't fit a true pacman stick due to space). Will a restrictor plate work.
3) When you wire the 4 way do you just wire it into the same part of the encoder as the 8 way i.e both the player one 8 way and the dedicated 4 way share the same terminals on the encoder. the 4 way just cant send the diagonal
As far as my setup- I bought a project someone else had given up on (well never started). I have
1) konami cabinet in good condition (no artwork or marquee)
2) control panel/box pre drilled for 2 8 ways with 6 buttons each for fighting. a 4 way with 2 buttons. a spinner and a track ball. with six other buttons available.
3) P4 computer with 20" samsung crt monitor
4) Control panel artwork (lightning)
Thanks
Paul
