OK, I'm working on a patch. It thoroughly changes just about every file. But I don't think it will be too controversial, because... it only adds comments!

Yes, I'm sick to death of not having any comments in the code. (Except a few randomly placed cryptic ones).

So I'm commenting it all! Now people will know what each file does. And they will know what the important functions do. And they will even know the basic specs for the hardware it is emulating.

Currently I've got so far as bios.h and bios.cpp.

Commenting is actually surprisingly fun, and it is useful to people and a useful learning experience for me.
