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! :)

  • Text to Speech apps and other apps that flood the speech synth, ignoring the control bits, do not work (ie: TE2)
  • DSK image support is mostly read-only
  • Uninitialized memory detection does not work on AMS RAM
  • 80 column mode does not work with screenshots, AVI recording, filters, or any stretch except DIB
  • 128k mode is very untested and not guaranteed to work - nor is it intended to be improved later
  • F18A support is very very incomplete
