I've tried to perform this save game comparision myself but since there are thousands of hex values changed just by adding a single item to the inventory, it feels quite impossible.
However, what I managed to do was actually to locate the north/south and west/east addresses for the player position. This means you can teleport yourself to restricted areas. I have not tried what happens in the Talamari guild yet, but for future documentation I will add a small guide here and maybe other people will be able to make use of it. Since the door is locked to the room in the Talamari guild with this magic fence, you can never enter the room. But using this teleportation could possibly get you into that room and also out from the room again. Not sure if you can pick up the items or buy them, I have to test that later.
These are the addresses for North and South: (they all have the same value and all of them must be changed at the same time to the new value.)
0058C710
0058C71C
005D4EE4
00600730
00639E60
These are the addresses for west and east: (they all have the same value and all of them must be changed at the same time to the new value)

1. Download Cheat Engine from here:
https://www.cheatengine.org/
2. Open up the Lands of Lore 3 game
3. Start the game so that you're moving around, or load a specific save state file where you want to enter a locked door.
4. Minimize the game window, ctrl+alt+del and then click on "task manager" was the only way for me to minimize the game.
5. Add the addresses above manually in Cheat Engine by clicking Add Address Manually (they should be found in the green coloured lol3.dat)
6. Try it out by freezing all the addresses. Select all of the added addresses and press Space to lock them
7. Reopen the minimized Lands of Lore 3 again, now your position should be locked and you can't move anymore. Woohoo! Then it works
8. Carefully increase/decrease the numbers. There are 5 addresses per coordinate, so if you want to move north, you need to change the value of all the 5 addresses (select all and press Enter and change number). Then reopen game and player position should have moved.
---------------------------
Well, it's not much, but it's better than anything else since I did not find anything for Lands of Lore 3 on the whole internet apart from some trainer where you can increase HP/Gold/MP or something.
FYI Addresses can also look like this i.e "lol3.dat+18C710" etc etc...
Also, increasing the value by around 5.000.000 (5 million) should be approx 1-2 metres in real world and enough to pass through a door if you stand next to it. I tried it myself and could enter talamari guild immediately without performing the first quest.
