The GCC patches are promising I must say, haven't looked at VBCC lately but any improvement is nice.

Given how clean the 68k architecture is it's strange IMHO that compilers should have any problem generating good code, a compiler that use the (mostly legacy) quirky instructions of x86 instead of a "RISC" subset having problems sure - but 68k? The only real "problem" is the split D and A register sets and that's not too hard to work with...

I have never been good at compression/decompression code however the LZSS decompression code in the logo routine(s) feels odd. Feels is the right word as I haven't really analysed it.
