Last change on this file since 625 was 293, checked in by krille_n_@…, 13 years ago

Commit 1/2 (Library, Configurators and Serial Server):

  • Changed Emulate.inc so that making 286 and 386 versions now works. Additionally, only one processor type define is needed in the makefile.
  • Minor optimizations.
  • Fixed spelling and did some cleaning.
