This is a public release 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

Please see the included file ChangeLog.txt for a full list of changes, including minor bug fixes which may not be listed above.
