Hi there,
First post here. Glad to join the community and looking for help on reviving my assembly code games and apps !
TLDR: Any chance that my Quarterback backup is not corrupted? Please see the attachments: screenshots and an image of the first floppy of the backup.
I have 7 floppy disks, which I think should be a Quarterback v7.2.1 backup. They contain assembly code I wrote in my teens: I can recall a split-screen spaceship race game with basic physics (thrust, gravity, air friction and collision detection), a fractal generator with point-and-click zoom capability (Mandelbrot & Julia), and a demo-like 3D text animator. That was more than 30 years ago. I'm eager to see it run again.
I have got @RobSmithDev's marvelous DrawBridge Arduino floppy disk reader/writer. All 7 image creations went more smoothly than I could ever imagine. 100% error free.
They all start with these distinctive four bytes: Qb0x (where 1 < x < 7). I also found a Quarterback floppy in my old cardboard archive box. It is v7.2.1. It must be the one I used back in the 1990s to back up my HDD folder where my code was stored to these 7 floppy disks before I sold my A1200.
But... Quarterback says my backup is corrupted. My hex editor shows clear, uncompressed assembly code and comments in the first image (see attachment). Heck, I thought Quarterback compressed the data! Is it a clue?
Your help is greatly appreciated. I will love to share the results when I'm done restoring these floppies!

You could give this a go https://github.com/keithgh1/AmigaQB_extract

Thanks for pointing me to this resource ! I'll try it if I can't get the directory structure with Quarterback.
The only thing I can think of right now is to try as many QB versions I can before I give up and use AmigaQB_extract.
If anyone has another idea, please share it ;)

Quarterback 5.12 did the trick.
Restoring backup...
