Changes:

  • Another round of optimizations. One notable change is that the code in IdeIO.asm for the XT-IDE rev2+ controllers no longer uses a lookup table to switch A0 and A3, at least not by default. A define (NOSWAPA0A3LOOKUPTABLE = 0, 1 or 2) can be used to select between 3 different alternatives of which the first (0) is the old lookup table code which also requires the most ROM space. Vcfed member Malc has kindly benchmarked all three variants and found no differences in performance so the most space saving option (2) is now the default.
  • Another notable change is that the optimization to MenuAttributes.asm required project wide changes in the form of an additional define simply because of how bad the implementation of the origin (ORG) directive is in NASM. Even calling it half-assed would be praise.
