🏰 Legend of Elya — World's First N64 LLM Game
A nano-GPT language model running entirely on a 93 MHz VR4300 MIPS CPU. No cloud. No cheating. Real 1996 silicon, real neural inference.
What is This?
Legend of Elya is an original N64 homebrew game featuring Sophia Elya — a character-level LLM (nano-GPT) running live on-cart on the Nintendo 64's VR4300 CPU. Sophia generates responses in real-time, constrained to printable ASCII, with no floating-point (the N64's FPU lacks trunc.w.s ) — everything runs in Q8.7 fixed-point arithmetic.
This is believed to be the first neural language model to run live inference on N64 hardware.
Game Development Applications
This isn't just a tech demo — it's a tool for N64 homebrew developers. Running an LLM natively on N64 hardware enables game mechanics that were impossible in the cartridge era:
