Programming a GBA Game on an iPhone

A developer created a GBA (Game Boy Advance) game entirely on an iPhone using tools including iSH (a Linux shell for iOS), the Textastic text editor, and the Delta emulator. The short Bitsy-like game called "TO THE TOWER" was compiled using gcc-arm-none-eabi and is available to download on itch.io, demonstrating that full game development for retro consoles is feasible on mobile devices.
