EDIT: Starting to put some stuff on GitHub, check it out if you want. I'll just leave this here.

Do people actually read and care about these things?

May as well write one for the sake of it. Even if it doesn't match too much with this site.

I've been getting back to my roots recently, been straying away from Half-Life 1 and going all the way back to Game Boy Advance programming. It's always something that I've enjoyed, especially since when I was a lot younger. Hell, it's what got me into programming as a hobby today. It's always fun to see what you can do with such an old device with limited capabilities.

And on the way I've picked up some new tools, guess the latest devkitADV build from 2003 is a bit dead now don't you think? There's a new, updated version called devkitPRO and it looks a lot better. Also learned how to use Makefiles on the way, which is useful in my opinion, no more using nasty Batch files.

And the best part for me, it's in plain old C. No more of that C++ to deal with right now. Not as if it's that different though.

Maybe I'll release my work on GitHub or whatever. Even if it's a bit irrelevant to post here.

I read them! Homebrew GBA programming sounds really cool, keep us updated!

"Do people actually read and care about these things?"
Yes, but it depends on who you ask.

I find 90% of the journals here interesting, so I read them. In some cases, like this one, I learn new things. I've never known about GBA programming's existence, and now I do. :)

Oh hey, I thought the same about my laptop! :D

If you're into retro programming or obscure stuff there's this guy on youtube, Bisqwit, I know about him from a friend:
Here's his youtube channel.
You should check him. Afaik, he's actually a bus driver.

Sounds pretty fun, though I know I'd get annoyed to no end bumping into the limits of the hardware.

Post your homebrew roms!

https://github.com/EthanAG/GBA/tree/master/gbaray
(It has an actual .gba you can run.)

Just finished fixing up an old raycasting tutorial, trying to upgrade old code from old compilers and added some useful stuff to it. It's a start.

Next is to add a real map format and remove more useless code and be able to choose maps and load them directly instead of having a header file. Also being able to increase map sizes and all that. Mostly still pre-defined stuff.

EDIT 2: But more importantly is to fix TinyGL, a basic OpenGL implementation that works on the Game Boy Advance. Only works on HAM and it needs a hand to go every step to get it to compile. Hopefully I can or someone convert it to devkitARM just so modern people can enjoy it.

Shame there isn't such a huge community anymore.

Ray casting for GBA? Awesome. I gotta check this out
