I am an unorthodox programmer, specializing in C++. Rather than focusing on standards and compatibility, I prefer minimalist and optimal technical solutions. If I can make a better wheel, I will happily reinvent it.
I am most known for my emulator, higan, which emulates all classic Nintendo hardware from the Famicom to the Nintendo DS.
To benefit higan, I’ve begun a project to preserve Super Famicom games from all regions. This involves purchasing games, scanning their boxes and manuals, hashing the ROM data, and documenting the board layouts to improve emulation.
I also work on fan translations of classic Japanese role-playing games. Specifically the reverse engineering and reprogramming portion. Most notable would be my work on Der Langrisser, and a small role in Mother 3. I write many tools to this aim: bass, a cross-assember; mosaic, a sprite viewer; curse, a hex editor; and of course, higan.
For the past several years, I have studied Japanese, with little success in reaching fluency. On that note, my name is Japanese for “making a mistake.” It’s a long story, but essentially it’s a reminder of humility.
