The simplest description I can give is to say that the time I spent on these programs was only enough to get a working version for MacOS.
Motorola 68k assembly source to ".s" format objects,etc.
SimAcid - lots and lots and lots of ScrollRect()s
SimScramble - Block shifts.
Flames 68K - A port I made from PowerPC just to see how slow my 38MHz 040 is. :-)
