Hey 0xCAFED00D, I had asked a month or two ago about porting tac08 to RetroFW and you seemed willing to look into it. Since then, one of the talented RetroFW devs took your most recent posted source and was able to port it without much hassle, but it is the older code from before you had sound etc. working. Aside from that, it worked fantastically.
Do you plan to release the updated source in the near future? The dev in question is possibly willing to port the updated code to RetroFW, and possibly also Bittboy, and GKD350h, maybe saving you some time and effort and helping spread the love :)
