gbdev/rgbds v0.9.1

on GitHub

Happy (belated) New Year! 🎊 🐍

Our GitHub Actions CI now tests RGBDS in Cygwin x64 and FreeBSD 15.0, verifying that it can build and run correctly on those platforms.

Added

• All programs now support -h or --help arguments to print usage information

Changed

• ld [$ff00+c], a and ld a, [$ff00+c] instruction syntax is not deprecated any more!
  • The 0.9.0 release deprecated ld [c], a and ld a, [c] (since ldh [c], a and ldh a, [c] are more appropriate), but also deprecated the [$ff00+c] syntax, which this release undoes
• The undocumented 99,999-argument limit for macros was removed
• Floating sections may be output in a different order

Fixed

• Fix undefined behavior with backslash at EOF in macro arguments
• Avoid errors after missing INCLUDE with -MG
• Object files used the MACRO node type for FILE nodes since 0.8.0
• STRLEN and STRSUB would cut off early on incomplete UTF-8 strings
• CHARLEN and CHARSUB would cut off early on invalid UTF-8 strings
• RGBGFX -u deduplication would fail without an input or output tileset (e.g. only an output tilemap+attrmap)
• RGBFIX could output an incorrect ROM if a write syscall did not write all the bytes given to it
• Correct the gbz80(7) documentation for the DAA instruction

Thanks to @Rangi42 and @ISSOtm , @robbi-blechdose , @avivace for the work done for this release.
