Viability of data recovery?

Somewhat hypothetical situation:

Computer user wrote a games application in the mid-1990s stored on floppy disk (non-MFM format; actually, GCR, or Group Code Recording). User has tried virtually everything to recover the source code to this game, and even sent said floppy disk to data recovery lab for analysis.

Other than remarking to client that data recovery would cost "several thousand dollars" and "wasn’t, generally, worth the expense," said lab sent disk back to consumer.

Short of using a time machine to go back in time and recover the lost source code, what is consumer to do in order to restore the lost data (besides spending countless hours rewriting it, which isn’t a fun/desired option)? I’m assuming even places like NASA/NSA would give consumer blank and weird stares given the oldness of the storage medium, and perhaps wouldn’t be helpful in recovering the data at all.

Thanks,

Ok, this is embarrassing…TRS-80 level embarrassing. The game was written for the Commodore 128 (an old computer like the Commodore 64).

Floppy Disk Data/File Recovery!! HELP!!?

I want to recover some files that I have in some floppy disks. I´ve tried several softwares and some of them have worked. Tried Undelete Plus and Recova but none of them worked for me (with Undelete Plus I don´t know why but I only had the option to scan C: drive only, not floppy or any other drive, and Recova found errors and didn´t do anything for me).
The one that worked is Active@ Floppy Recovery 2.0, it showed all my files in the floppy disk! But as it is a demo version I cannot recover all my files.
The thing is I´m sure my files are there and I can recover them but I need a good FREE software to recover them ALL. I don´t want to pay since there are only 2 floppy disks and I´m never going to use the software again!
I no longer use floppy disks! It´s all about USB memory disks now….

Please tell me, which software do you recommend?? please please pleaseeeee!!!

ps. the problem with my floppy disks is the classic note that they no longer have formatt and if I want to formatt them… but I haven´t done anything like that cuz I know I can recover my files….
