Adventure of Norris (Amiga\UAE) Collision cheat

Hi all,

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

replace with

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


Thunderboy (Amiga\UAE) Collision cheat


This game has no less than twenty five one-hit kill collision checks. Imagine yourself sitting there in an air conditioned room making all those manual edits using Action Replay…and then you have to know all the offsets…and the offsets will change on different machine configurations. Forget it.

Load the game up in WinUAE and make sure the game has started proper so you are actually in the game, then make a save state…but no so fast. You will notice under the save game File name prompt it says ‘WinUAE snap shot files (*.uss)’, left click that and select ‘Uncompressed (*.uss) and then click save.

Now, deep breaths, you won’t be expecting this – open the save state file you created with your trusty hex editor (e.g. XVI32) and replace all occurrences of the following string

29 7C 00 00 00 01 84 12

Replace with

29 7C 00 00 00 00 84 12

Save the changes you made in the hex editor and close it off. Now, go back to the emulator and load the save state.

tbd¬†Yes! Now there are no more one-hit kills, enemies safely pass through- you’re invincible!
