source: xtideuniversalbios/trunk/Assembly_Library/Src/Menu/MenuInit.asm@ 537

Last change on this file since 537 was 532, checked in by krille_n_@…, 12 years ago

Changes:

  • Changed unused.pl to remove a false positive when MODULE_STRINGS_COMPRESSED is not included ('loop PrependOrAppendSpaces' in DisplayFormat.asm).
  • XTIDECFG: Moved the contents of all text files under Help into Strings.asm to simplify editing and to avoid them being "out of sight and forgotten", essentially making it easier to keep strings up to date. Also made changes to some strings in the process (spelling mistakes etc).
  • Other minor fixes and optimizations to the BIOS.
