Adventures of Norris is a pleasant wander-about collect ’em up game with good gfx and nice moody music. I personally think it is a bit better than the official Jet Set Willy on the Amiga since unlike the aforesaid port, it retains the room naming convention and flick-screen nature like the original Speccy JSW so you can more easily map it out.
I wanted to do AR cheats for this, but I tested with a couple of different disks and it just didn’t work out. Anyway, this is the compromise…
Make an uncompressed save with UAE, and then open it with the hex editor and make the following change
FF A0 4E 75 33 FC 00 01
FF A0 4E 75 33 FC 00 00
Now, reload the modified save state in UAE and you will notice monsters now harmlessly pass by you. If you need more help\info, maybe look at this post
