I'm hoping that, this will work just as well with Turbo Modes as Wolf64 did.
Turning with the mouse also (even though the original Wolf3D and Doom booth had more than just turning with the mouse, you could use it to creep forwards and backward very carefully in both. But modern shooters did all away with that in favour of full mouselook later). :3
Since DOOM Mapping tools aren't going to produce compatible WAD files, I wonder if your selfmade mapping tool could be bundled with this at some point. Of course it would be magic if such a tool was also a C64 tool but I don't wanna be crazy here. :3
Hope you are doing well!!
