so I think I've got that last problem solved. But there's a problem in my fitness function, such that if there's an error in the creation of the file needed for analysis (in this case, caused by evaluating a beast with no genes at all), the fitness is inordinately high. (it gets a fitness of 0, which for this test, is the best possible).
So, evolution being the dirty, cheating fink it is, jumps all over that.
It sorta makes me happy, but it's still a low-down filthy trick.

My life has been made 100x easier. So, I finally got the whole DC toolchain rebuilt. (I'll start with the bad news first -- yeah, there's bad news) Since I had to rebuild it, I figured I'd go with a brand-new, shiny build of everything, rather than the dusty old versions I was using. So I've got GCC 3.4.3, binutils-2.15, newlib-1.13.0, and the latest version of KallistiOS. Everything went through seemingly w/o a hitch, until I tried to test the cel-shading demo. It don't run. No errors or warnings. Just don't run.

Soooo... what's the good news? Well, my testing process has been a little... convoluted, through necessity. The coder's cable (what ya use to transfer a program to the Dreamcast to run it, w/o burning a CD) doesn't work on my Mac. So I have a poor, lonely, Windows box w/o a monitor (Johnboy) connected to the DC. I use VNC to access that, FTP back into my machine, grab the file, and upload it to the DC. Except the old Windows DOS prompt doesn't have a scrollback buffer... So oftentimes, logs get lost.
Well, since I got my old laptop fixed, I built dc-tool for that, instead. Now instead of VNC, I can just telnet into the machine connected to the DC. And linux is a lot nicer than DOS. Full scrollback, better command history, etc.
This'll make troubleshooting my current problem, to round this post out w/a nice sense of closure, 100x easier.
