What is DeiMOS superoptimizer?

DeiMOS is an open-source tool that finds provably optimal MOS 6502 assembly sequences using constraint solvers and random search, slashing cycles and bytes.

How do I use DeiMOS for 6502 coding?

Install via Cargo (it's Rust), feed it assembly patterns via CLI, and get optimized output to drop into your projects — perfect for C64 or NES homebrew.

Will DeiMOS work on modern chips like ARM?

Not yet, but its framework ports easily; expect community forks soon for embedded efficiency gains.
