This is a release candidate of WinFellow v0.5.10. Compared to the earlier version 0.5.9, the following changes are included in this build:New features

• a native ARM64 build of WinFellow is now provided as part of the release zip archive

Bug Fixes

• Thanks to the availability of Toni Wilen's cputester, the following mostly CPU related issues from the basic tests could be addressed:
  • Removed address register as byte source operand in move.
  • Various bit-field instruction fixes.
  • Incorrect pack/unpk behaviour.
  • Trapcc increase pc after condition check to get correct exception stack frame.
  • Cas2 select the first compare result value when both compare registers are the same register. Set v flag.
  • Link/Unlk incorrect result on stack when link register was a7.
  • Split long reads in two word reads for correct values across banks that are not stored consecutively.
  • VPOS wraparound fix.
  • Exception cycle time changes.
  • Fixed various instructions that overwrote exception cycle times with regular instruction time. (when triggering privilege violations etc.)
  • Set div cycle times to values closer to the listed cycle times. Still not dynamically calculated, but should be closer.
  • Don't trace when instruction was aborted by illegal, privilege or address error.
  • CHK.w N flag fix.
  • EOR ea vs. data register check for cycle calculation was inverted.
  • Changes to cycle calculation for BSET/BCGH.
  • Set undefined div flags according to behaviour on 68000.
  • Move to SR, check supervisor level before evaluating ea.
  • Include exception time in cycle time for chk.
  • Handle bkpt differenly from illegal.
  • Broken overflow and other special cases for mull.
  • Handle supervisor check differently for move from sr to avoid returning result when throwing exception.
  • Missing address mask in rtarea memory handling (for when upper address byte contains data).
  • Trapcc had wrong pc in the stack frame.
• fixed mouse capture for older RetroPlatform hosts

Maintenance updates

• code refactoring:
  • solution file reorganisation
  • static analysis/replace custom datatypes with standard sized C++ types
