So I think I still have a floppy disk of this particular version of ROL3 somewhere, which had a readme that was barely even started (I'm unsure if it's the one that recreated the game logo in times new roman, though). But yeah it was the only beta that was never released publicly.
If that floppy disk still has the files (I don't have a floppy drive handy to check), could it be sold for a fortune on Ebay or as bonus item with some of my calcs for collectors?
I even have floppies of Illusiat 5 PC, where the game is not compiled. Somebody asked for that copy once, which is no longer online, as he wanted to extract the images. I'll definitively have to check this out at one point too, assuming my floppy disks were not erased by magnets or something like my 2002 calc games backup.
