Yeah the GBA uses an older ARM processor and is really well supported by GCC and modern compiler toolchains. Heck you can even write Go and run it with TinyGo

Yeah the GBA uses an older ARM processor and is really well supported by GCC and modern compiler toolchains. Heck you can even write Go and run it with TinyGo targeting the GBA: https://tinygo.org/docs/reference/microcontrollers/gameboy-advance/ https://tinygo.org/docs/reference/microcontrollers/gameboy-a... Plain old C/C++ is really well supported for hobbyist development though: https://github.com/gbadev-org/awesome-gbadev https://github.com/gbadev-org/awesome-gbadev
