It looks like the code had a stroke.
I checked other repositories but they had the same .dsk image. If you have access to an original, please passport it or .woz it.

Using the RDOS 2.1 boot disk, I was able to load BISONE into applesoft basic and list the code. I could try to edit those lines. Where is the french version that was mentioned here?

Using an RDOS 2.1 boot disk, I was able to load BISONE into applesoft basic and list the code, but I'm not able to follow the French version, it appears to be revised.

Not only are the line numbers different, the disk is DOS 3.3 rather than RDOS. I wonder if the person doing the French conversion was given the original developer disk rather than a production RDOS disk? Whatever the case, the afflicted code in the English version is the save-game code, which will not be at all alike.
Curiously, the copy protection appears to be in "PHONE BILLS" rather than "QWERTY".
( ftp://ftp.apple.asimov.net/pub/apple_II/images/non-english/f rench/misc/computerre_lepisodebismarck.dsk)

Any luck? I looked for the .woz on Asimov but didn't find it.

....assuming only one sector got corrupted. Most of the game is Applesoft, so problems will likely be easily noticeable. Unless there's a quiet single-bit error in there somewhere.
Of course, 40 years later, any original disk is going to be a dice roll, but ideally the sector checksums point out most of the problems and a diff of the images will identify files that require closer examination.

I feel like a pinball game from SSI should have turn-based movement and a hexagonal ball.

I copied it to a floppy and it runs fine on my //c. Many thanks!
