Quoted from Drickey86:
This may have already been addressed but does anyone know if the pinsound board is only compatible with the system 11 titles listed on the pinsound page or would it support most system 11 games? I would love to try it in BK2K and make a custom mix but hate to gamble with the board on a hmm wonder if this will work
I could be that there is some compatibility issues with non-listed games, or maybe they just haven't had access to extract the sound files from the titles not listed.
For 100% certainty, I suggest you PM @PinSound. Only other way I would trust responses not directly from PinSound is if someone has actually installed one successfully on BK2K, and can provide details.
