The full story
SnesGPT is a tiny transformer model, after Andrej Karpathy's micro-GPT, running on a Super Nintendo in 65816 assembly. It generates names one character at a time using a 1-layer, 16-dimension, 4-head model with fixed-point arithmetic, using the SNES's hardware multiplier. It was an experiment to see how well Claude Code would cope with the task, and it did surprisingly well. The ROM runs in the Snes9x emulator.
