Sushi - A Gameboy game

This is a blogpost I’ve been meaning to write for a long time, it’s about a game Nils and I wrote back in January 2017 for the Inno Games game Jam. That game jam happened together with the global game jam and the topic was: Waves. The source code for the game can be found here

Nils and I both like challenges and even before going to the game jam we had decided to write a game for the original Gameboy (1989) and we decided to write it in assembler. This was inspired by the Ultimate Gameboy Talk at the 33c3 that happened in December of 2016, so we bought a Gameboy Advance and a Cartridge that is capable of reading SD cards. Both arrived about a week before the jam and we hacked together a quick prototype just to get a feeling for the architecture and the instruction set. I also ended up writing an IntelliJ IDEA plugin that supports Z80 assembler and integrated the RGDS toolchain (assembler and linker) as well as the emulator.
