Subject: [PATCH] Add hash-bench-nes to Home Consoles/NES
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A cc65-based NROM ROM that times 18 hash algorithms on the 1.79 MHz
6502 and displays milliseconds-per-iteration on screen.  The
implementation deliberately keeps to the algorithms whose state fits
the cc65 toolchain's no-uint64_t constraint (so SHA-512, SHA-3,
xxHash64 etc. are dropped; everything else carries over).

Useful as a worked example of practical cc65 usage on real NES
hardware — passes Mesen2 cleanly; FCEUX has WRAM-mapping issues
documented in the README.

- Repo: https://github.com/dmang-dev/hash-bench-nes
- v1.0.0 release with prebuilt .nes:

- License: MIT
- Built with: cc65
