Strange thing.. The 'Future Crew' bug I heard about had to do with the fact
that their mega-demo titled "Second Reality" would crash on any systems with
more than 8 MB of RAM. Although it seems that that isn't true. I've never
heard of an S3M playing bug and I don't understand why it would be called
the 'Future Crew' bug since FC never made an 16-bit mixing routines. One
thing to consider is the mixing speed. The C mikmod routines, although
optimized with -O3 or whatever still will be very slow compared to the ASM
mikmod routines. In fact, mikmak himself told me that he didn't optimize his
C routines. I myself have seen demos that use 16-bit mixing and don't slow
down at any point or place. I don't see any reason why such a thing would
happen. I have programmed my own S3M player and it is in DJGPP code although
the routines aren't stable enough to be distributed. I am completly rewriting
the routines to support more formats including .IT which mikmod currentely
( to my knowledge ) doesn't support. Besides this, the routines will be
fully compatible with DJGPP ( and other compilers ) and will have hopefully
the highest quality and most optimized mixing routines of any MOdplayer or
library out there. When I finish this project, you DJGPPers will know.. :)
I am debating whether to include the source code or not. We shall see as the
project matures.
