Forgot about Qsound. Well maybe some talented soul will be able to recreate the A board to go along with a multi kit, at least for the cps1. CPS1.5 boards are getting much harder to get.Sure but if the conversion uses a CPS1 mobo you can't have Qsound, so they are replacing the music (with music from other CPS games) or its just silent.There are a lot of peeps doing CPS1.5 game conversions to use the CPS1 mobo nowadays since the CPS1 mobo is more attainable. I wonder if a reproduction of the CPS1 mobo could be done at a low cost with newer, more reliable components?!
The CPS1 mobo uses some custom chips from Capcom, even IF everything was completely documented (its not)...
We would still need to pay a fab to put the design (back) into production.
