Ok I solved my Issue, I think:) My ipac can only support one shift and there is no way around it....... even if it did, when the other shift was used it would affect my side as well,, so hiensight can be a Biscuit, aint it the truth?....... If I had an Ipac4 it has 2 shifts and one does not affect the other.(Hence I could have used the player 3 side for player 2).... But since I had a two player cocktail I thought hey save a buck? Anyway next time I will either use an ipac4, or just use 6 or 8 buttons....... per side..... oh yeah I got my joystick shift commands figured out as well.....
**LESSONS FOR THE DAY***
1 plan for upgrades
2 plan for the unexpected
3 although rgb buttons cost 7 bucks a piece vs 2 for regular, DONT be a cheapa$% like me. front for the other 28 bucks for a six button rig. Neo-geo config looks great but less functional.
Hope that helps future builders:)
