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! :)

    (2017-01-07)
  • rewrote speech synth CPU halt system, but this didn't fix anything that I could see
  • bugfix in image disk sector allocation that would leave empty holes on the disk
  • bugfix in image disk writing cluster list that only wrote one sector per cluster ;)

  • disabled VDP warning, it's still not quite right

  • Notes
    Source code is now on Github at https://github.com/tursilion/classic99
