2024, February 29th - New official mirror site launched

Since recently the main hosting server has suffered from outages, we have launched a backup mirror host. So, feel free to use the equivalent repositories for rmac and rln.

If possible, use the main server to report issues, as the backup site currently has no way of notifying the authors about issue creation. E-mail is also a valid alternative.

2023, March 20th - rmac 2.2.15 released

This is mainly a bugfix release, which addresses changes introduced in v2.2.14. More specifically, the code against exporting fixups that are used as a part of an expression was too strict and produced an error on symbols that could actually be fixed up by the linker.

The Windows 64-bit and 32-bit, Linux and OSX/M1 versions are ready to download, or alternatively visit the downloads page.

  • Added support for Commodore 64 .PRG output format (-fc)
  • Added guard against exporting fixups that are used as a part of an expression
  • Added support for -fr switch and 6502 mode
  • Fixed a bug in floating point number parsing

2022, May 31st - rmac 2.2.2 released.

Changes since last release:

  • ds directive now works with expressions that have undefined symbols (as long as they are resolved by the end of assembling)
  • equr has been overhauled and now works with all target architectures
  • Label names clashing with register names is now restricted to target architecture register names. As an example, this means that a label name of “a:” is now illegal only if the selected architecture has a register name “a” (at the time of writing: DSP56001 and 6502)
  • Printing a listing with -l* now doesn’t print \f characters when printing the symbol table

There now exists syntax highlighting support for the editor 10x. If you have the editor installed, simply download rmac.10x_syntax and place it in your %APPDATA%\roaming\10x\Settings\SyntaxHighlighting folder. By default it works for .s files but it can be easily changed to support other extensions as well
