I had this educational game called Read & Rhyme for my Atari ST as a kid. I can't find anyone else's dump, and the program seems to crash in my own dump, but its image files are all intact.

Three more image dumps from Read & Rhyme.

I don't remember quite how this game played. I definitely enjoyed the space theme as a young child.

Apparently the last track on this disk was left unformatted as a form of copy protection. 💾🔒

There is an Atari ST dump format that can handle this called STX but it is hideously complicated, closed source, undocumented, and its only dumper program needs to be run on an ST. :(

This seems to be the best current reverse-engineering of the proprietary Pasti STX format. There's a lot to learn here before I'd be able to make use of it.

So as a first step, I wrote a Pasti STX parser just to verify the file structure and dump it out as something human-readable.

There's still tons to work out about how the format works but at least I can inspect and verify all its data now.

I found this amazing resource explaining how floppy disks work! Gets way into the technical details. 💾

After writing a program to do some lower level dumps of this floppy disk, I think I've found a signature left by the company that original duplicated the game?

HLS DUPLICATION

So I got some parts to make a FluxEngine.

Was really easy to put together, and the components are inexpensive.

Time to do a deep dive into some floppy disks... 💾
