There is a bunch of GFA BASIC for Amiga files (the source code for Blender's ancestor, Traces, downloadable here: http://zgodzinski.com/blender-prehistory/) that I would like to peek at.

Despite my efforts, I couldn't find any software to open or convert these files to something readable and that would run on Windows 10 64-bit.

Is my only solution to run an Amiga emulator and somehow find a copy of GFA BASIC for it?

Looks like someone on Atari forum posted the text a while back: convert Amiga GFA Basic file to Atari - Atari-Forum. As you can't see the files without a login, I have mirrored them as text here: scruss/AmigaTraces-GFA_Source: BASIC source for the forerunner of Blender.

X11-Basic, a modern GFA BASIC implementation, will likely not run this source. Portability was not GFA BASIC's strong point.


I think you could use GFA Basic 32 to run GFA Basic programs on Windows. This should allow you to extract the source code from the tokenised file.

If that doesn't work, a hex editor and patience should result in you eventually figuring out how to extract the code from the tokenised file, a bit like this.

    I initially tried GFA Basic 32 but it looks like it only understands its own format, not the one of GFA BASIC on Amiga. Jan 4, 2019 at 17:08
  • @FrançoisBeaune Aw... You could direct a question to that site's info@ address if you want official support.

    @StephenKitt Yeah, that came across sarcastically; that was not the intention at all.

You can run Amiga GFA Basic (no idea about legal status) in WinUAE then "print" the listings to a file.
