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)

(2017-02-26)
  • fix bug with multi-bit CRU instructions - byte flag was set wrong way around and broke register auto-increment
  • add support for F18A SPI flash interface (upgrade program runs now)
  • also means that CKON, CKOFF, LDCR and STCR on the F18A work now
  • fix sector allocation when writing to disk image files to more closely match original TI controller
  • add support for more of the F18A status registers and reading them from the host
  • move source to Github - https://github.com/tursilion/classic99

  •  
    (2017-01-14)
  • Minor bugfix - image disk file allocation performed more like the TI disk controller, doesn't overwrite copy protection on Bubble Plane

  •  
    (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 ;)
  • change image disk sector allocation - FDRs at the beginning, data at the end. Makes for nicer layout

  •  
    (2017-01-03)
  • update palette colors (suggestion from Sometimes99er)

  • re-added VDP warning (with a little more state awareness)
  • add optional FPS display
  • automatically disable disconnected joysticks (was causing slowdown in some cases)
  • fix F18A multiple palette support on ECM0 tiles
  • fix 5-sprite-on-a-line flag

  •  
    (2016-11-06)
  • Patch for XB256 'DELAY' call
