If this software is cool or useful to you, consider a small donation to the programmer! There is *no* need to pay to download and enjoy this software! But it's a lot of work and I do it in my so-called spare time, so a couple of dollars would be really appreciated! :)

Last Updates (max 5)

  • v399.004
  • reset more of CRU on menu-reset
  • add 9901 timer to the debug register pane
  • don't reset the 9901 timer every time you leave timer mode (fix for CamelForth)
  • more disk DSR warnings (hate that disk DSR so much...)
  • allow the disk corruption break option to catch the DSR warnings too
  • update manual for 9901 line

  • fiddled with AVI audio, but no improvements. AVIs updated to 60hz otherwise.
