Here is one more version of the Lemmings HD installer in the attachment. This version is chronologically between two version previously uploaded. Just in case.
I don't see much people are interested in this here, but let me, anyway, report about my experience with these installations.
I was successful in installing 'Lemmings' and 'ONMLemmings' on the hard disk. It's not just a trick with images of the floppy disks on the HD. Files are really extracted from the disks.
It's "sort of working". Games to easily freezes. I wasn't able to finish Fun/Tame rating without lock up (I've tried several times). As I was done all this (installation and playing) on the PC with WinUAE, I can't say it's not just emulator's fault, but somehow, I have a feeling these HD installs are far from perfect.
