Hello! This is a brand new adventure game for the Game Boy Color. It's about my cat Anise, having adventures.

I'm also writing about the entire development process in gratuitous detail on my blog, if you'd like to follow along!

The canonical source for builds is Patreon, where you can get access a whole week early for only $4 a month! I may also upload builds here, um, when I remember.

A Game Boy Color emulator is helpful! My favorite is mGBA (I'm using recent builds of 0.7) — try loading the gba-colors shader for a more pastel aesthetic. Allegedly, BGB is also good for Windows and SameBoy is good for Mac.

Of course, you could always play the game on actual hardware, too.

You will need:

• rgbds, the recenter the better
• Python 3 with Pillow installed
• make

Do the following:

make

Wow! You did it. 🎆 Enjoy!

(Actually, you probably didn't — currently I have some intermediate build assets that require manual intervention to actually get working. Sorry! I'll fix it soon. Or maybe I already did, but forgot I put this paragraph in the README.)

I'll gladly accept advice on idioms and errors and whatnot, but would prefer no non-trivial pull requests — I'd like to be able to account, personally, for every last byte in the finished game.

That said, feel free to use this as a base for something of your own! The following may be helpful:

• awesome-gbdev, a massive list of Game Boy dev resources
• the official Nintendo Game Boy Programming Manual
• the very helpful Game Boy development wiki, which often clarifies or corrects or expands upon the manual
• a compact table of gbz80 opcodes
• rgbds's own documentation
