Please note that I've been trying to to work at this for a little while, and I do know that I should look into something simpler first, but I've been trying what I have. As of recently, I've been trying to work on how to create a Mega CD (or Sega CD if you prefer) PCM driver. I have been looking deeper into this sort of thing, and I've been finding in the manual interesting things that I need some help with understanding. As a side note, I have added the $ for the addresses on the address notes paper. http://pastebin.com/ptQVQqjf https://mega.nz/#!MIlU3TDK!c4MWZUNU5pkkCNFc1IWZJK-0B68phBndPNbCE3JB1hU Thanks, Gameboi64 Update: I have found more, it is at V.3 in this FAQ: http://segaretro.org/Sega_CD_programming_FAQ_(1998-12-06) I need help with more understanding what all of it means, as I know there's probably some people that know more about this than I do, so I'm seeing if I can get any help or info on this.
