SNES assembler for applying patches to ROM images or building ROMs

asar

history

Project history and usage

Asar is an SNES assembler used to apply patches to existing ROM images or create new ROM images from scratch.

Project history

The official README says Asar was originally created by Alcaro and modeled after byuu's xkas v0.06. The GitHub repository metadata describes the RPGHacker repository as the now-official home.

Adoption history

The project publishes GitHub releases and is packaged by several Unix package managers in the supplied Homebrew-derived facts, reflecting use beyond manual downloads in ROM-hacking workflows.

How it is used

Asar supports 65c816, SPC700, and Super FX assembly, can be run as a command-line patching tool, and can also be built as a DLL or static library for embedding in other tools.

Why package nerds care

Asar matters to package collectors because it is niche but practical: a retro-console assembler with official manuals, binary releases, and distro packaging despite serving a specialized ROM-hacking audience.

Timeline

2017: Official GitHub repository created.
2018: v1.60 beta 1 appears in GitHub releases.
