Libraries to help developing GBA games.
You must download devkitARM from here.
Then you can extract wherever you want in your system. I'll assume you extracted to /home/carlovan/.
Clone this repository: git clone https://github.com/Carlovan/gba-libs.git
Then modify the file Makefile: in the first line substitute ../SDK with the path where you extracted devkitARM.
In this case it should be :
BINPATH := $(realpath /home/carlovan/devkitARM/bin)
Now you are ready to compile!
First of all run make libs to compile libraries.
The you can run make to compile the test program to test.gba.
You can delete all binary files with make clean.
DONE! You can now open test.gba with your favourite GBA Emulator (I recommend VisualBoyAdvance).
