Found out & fixed what was wrong w/ the DC stuff. The newer versions of KallistiOS now use newlib, but because of whatever, a vanilla newlib doesn't work. So there's a ←patch, which solved everything. "Hello, world!" worked, as does my cel-shading demo. So the next order of business (or one of them) is to solve the broken texture problem.

thank god

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.

another hitch

none of my disc drives are working reliably so the backup all my cross-compiler toolchains are inaccessible at the moment. I either need to rebuild them, or find another method of getting them back. Either way, it's another pain I don't want to have to deal with. Ah well.

it's thinking

Been working on Dreamcast stuff. A cel-shading demo is up. Quite a bit more to do, but it's finally off to a good start.
