Opening / Extracting a Damaged HyperCard Stack

Hey all,

I've been working on a preservation project consisting of 400 and 800k Floppy Disks from the 80s. Unfortunately, one issue I keep coming across are damaged disks. Recently I came across a weird one and was hoping for some help.

Attached is a zip file containing the Disk Image for HyperTrainer! I've tried all verions of Hypercard and I was able to get the splash screen with the error Can's read card or background id 57936 at location 5454.

Is there anyway to open this stack in an edit mode to be able to work around the damaged areas?
