I've done one RosettaCode 68000 project: "100 Doors":
http://rosettacode.org/wiki/100_doors#68000_AssemblyI did it as a straight translation of the C version. It'd be nice if somebody does a version using structured controls and/or DBccc. I didn't just because I'm not as familiar with them. I'll probably do "optimized" (i.e., better algorithm) versions unless someone beats me to it.
Because the intent of the project is to allow people not familiar with e.g. 68000 assembly to compare it to other languages, I put in more "how this works" and "what this means to the assembler" comments than I normally would. Probably could use still more, though. I originally left the C code in as comments, but then decided to take it out. What do you think?
How to add a section wasn't obvious to me. What you do is edit the section previous to where you want the new one to go, adding a new header at the bottom. When you save it, it'll become a new section.
