Very nice! I'm going to have to wait until I get my PS2 setup going, though.
Out of curiosity, why am I seeing almost every major homebrew platform except the Sega Dreamcast? We have a huge homebrew scene, extremely modern tools (GCC13 with C23 and C++23), tons of examples, SDL, OpenGL, Lua, etc...
I'm one of the developers of the KallistiOS SDK, and you should totally check it out. ;)
So far all the ports I've done I've tested on real hardware one way or the other, so the lack of a Dreamcast port is just because I don't have one (getting things to work on emulators is one thing, but that doesn't mean that it will work properly on real hardware). At this point, I'd rather reduce the amount of hardware I have than add to it :)
