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. - 2024: v1.91 appears in GitHub releases. ### Related projects - xkas, SNES ROM hacking tools, SMW Central tooling ### Sources - - - ## Security Notes No matching local secret-handling manifest was found for asar.
