Oh, this was nice. I was late to the PC scene (got my first one in 96, had an Amiga before that) but Second Reality was still my gateway drug into PC demos, and the soundtrack was one of my favorite modules. Even got myself a second hand GUS to properly experience these things.

Not sure.

Yeeeeeessssss!

And beyond!

W000t!

Waaaaat!! Thank you!

Windows for now; Mac and Linux will follow at some point when we removed all the x86 assembly parts (which is about 80% of the code)

Most of it is relatively simple! Their "VGA timing" is really just "do stuff at the start and end of the frame", plus timing to 70Hz vblank, where you can just busywait between frames. The real sauce was in converting 16-bit assembly to 32 (no segments) and resolving planar mode renderers.

The original repo is full with unused stuff, but we didn't really look at those - porting the real thing was a large enough challenge!
