Do some archeology

When I talked about a legacy game with someone, s/he mentioned that s/he had a smarter solution to one of the insanely hard stages. Although I narrowly survived the onslaught (and therefore beat the entire game), I'd like to try it again. I did have saved the entire progress, but the savings were stored on floppy disks which are no longer readable, so I have to begin with the first stage. There were no USB flash disks by then, so I didn't have many backup options. By the way, I could try to extract some assets of that game and save them in free/open formats.
