Hello again CafeDood! I asked around the Discord community and one of the talented devs there agreed to try to port your fantastic tac08 to SDL 1.2 and RetroFW. However, the source files on the github are older, from March, and don't contain any of your recent improvements including working sound.
Is there any way you might be able to post the updated source?
Edit: I'm sorry, I was reading the older comments and see you did say you would not post updated force until you were happy with it. That said, once you do, it looks like the port to RetroFW will be a done deal.
