If this software is cool or useful to you, consider buying me a coffee on Ko-Fi! There is *no* need to pay to download and enjoy this software! But a couple of dollars would be really appreciated! :)

Tips and tricks video:

Last Updates (max 5)

  • fix GROM access to console GROMs from banks larger than Classic99 supports
  • also mask cartridge access in those cases instead of outright rejecting the access
  • some future todo notes added

  • Added View->Log Disasm to Disk to the Debug menu
  • Some work on SID debug but it's not visible yet
  • proper line counting in the debug output, so the cursor stays where it's supposed to
  • bugfix so that CLOSE doesn't return an error on devices without FLUSH (like CLOCK)

  • Add reset for timer statistics
  • add CycleCounts.txt output after timer block
  • Fix opening manual and disks for non-English Windows

  • fix disk full on image disks (would just keep overwriting the same sector)
  • fix crash bug in debug of writing very large files
  • fix recorded length of variable-length record files (would be off by 1)
  • fix reporting of errors on CLOSE (/all/ disk types suffered here)
  • updated Tunnels of Doom in CartPack to describe how to load the built-in games

  • add some missing closes to the disk image handling. should've RAI
  • add full directory sort when writing to a disk image to fix old broken images (this should also fix rename from the last update, but nobody had time to notice it was broken yet)
  • all the fixes made to saving FIAD headers never made it into disk images: bytes in last header and number record field were both wrong for variable type files
  • added disk size verification to TICC handler because the TICC doesn't check like I thought it did and PEOPLE ARE NOT PAYING ATTENTION TO DOCUMENTED RESTRICTIONS.

  • Notes
    Source code is now on Github at
