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! :)

I have a lot of database entries to fill in. ;)

Open source (but restrictive license) emulator including ROMs licensed by Texas Instruments - see documentation for license and restrictions.

Tips and tricks video:
Using the debugger:

Last Updates (max 5)

  • Another keyboard fix to prevent shift from being locked on

  • add keyboard debug
  • fix miscount of metakeys when overlapping keypresses that use them (such as the arrow keys)

  • added debug option 'ignore console hits' to not breakpoint from the console ROM range (0000-1FFF)
  • prevent previous folder up-navigation in FIAD paths
  • improve disk debug slightly
  • fix for RESTORE/REWIND not setting the record number in sequential file PABs

  • Fix for F18A max sprite register - F18A software that didn't set it would have no sprites at all ;)

  • updated fbForth and replaced XB256 with Isabella
  • CF7 emulation updated
  • gigaflash emulation (disabled, for the most part)
  • Many 9901 fixes: interrupt status bit, clock registers, wraparound from zero, and proper reset behaviour. This makes both CamelForth and cassette work with the same code, finally.
  • fix high-DPI scaling for heatmap
  • fix GPU instruction fetch, was buggy
  • add drag and drop support for cartridges - just drag the file onto the window and it will load and reset
  • F18A features added: text mode attribute colors, second tile layer, sprites per line, text mode sprites
  • VDP now resets differently for warm start vs cold start (mostly to preserve F18A palette on warm)
  • fix disk path history by allowing longer entries in the edit box
  • fixed a typo in the audio volume table

  • Notes
    Source code is now on Github at
