A C# WinForms program that decompresses and extracts files from the AT7 containers used for the Pokémon Mystery Dungeon Adventure Squad games for WiiWare.
A Python script to extract the music data from Metroid II: Return of Samus as RGBDS-compatible assembly code files, wth associated macros.
A rudimentary hardware demo for the Game Boy Color to demonstrate the General DMA feature's different results on the GBA SP versus other compatible systems.
A Python script that decodes and converts the .ani/.sld animation files used in the Brunswick Frameworx bowling lane computers.
A CLI program written in Rust that turns input text into an acronym that mimics the titles of episodes of Codename: Kids Next Door.
My CS degree's final project, a barebones BlocksDS/Nitro Engine/NFLib 3D game engine with bunnies, platforms, tank controls, jumping, fall detection, and bunnies, for the Nintendo DS.
Versions of Metroid games where nearly all text is thrown through multiple translations on Google Translate.
