Hey

I can't help, i'd like to congratulate you on not losing faith...but i'd be quite surprised if anything form of magnetic storage could last that long without degrading badly :\
Then again, your games work

"Amiga Forever" comes with WB emulation that I think you can put onto a disk, but amiga format DD disks are pretty different to PC HD disks...
I suggest you have a peek in the emulations section of the forum.
I'm pretty new also.
