You've just bought a tear to my eyes!!!
I wrote the Demo Club Catalogue program on disk 730... Back in 1990!! (it took me weeks diss-assembling other demos learning what routine did what, and then re-coding just the bits I wanted to make the program) - I even made it auto load a text file to show in the scroll text!!
Sadly I lost all my Atari disks during a house move, so never thought I'd ever see that again! - Can't wait to show my kids!!
Don't suppose you have a program called Bootsaver anywhere do you? - I wrote that as a GEM based program that could also be run as a desktop accessory - it allowed you to save bootsectors from game disks and restore them at a later date should they get infected by a virus.
I think the filename was bsave301.prg or bsave301.acc - again I lost the program and all the source code to it, but it'd be great to find it once again!
Many thanks Spiny, you've made my day!!
It's still better code than I can manage in 2015 I'll have a look for the bootsector tool, it sounds familiar, I may have saved it out to one of my archives.
edit: are you aware of the demozoo site ? I'm helping fill the gaps with Atari demos, and it looks like you have other disks already there: http://demozoo.org/groups/39784/
