Hey, i just have found this page, have some game genie codes that allow some prince of persia snes cheats, check it:

The most interesting feature was to disable the fall damage, that way you can go down to precipice without dead (except if there are spikes)

These are also listed on PoPUW:

It would be interesting to see what exactly they do.
I.e. what memory address is changed to what value.

There is a utility that can convert Game Genie code for various platforms:
http://www.romhacking.net/utilities/23/
If I remember correctly, a Game Genie code for SNES only modifies one ROM address per code, while a PAR (Pro Action Replay) code only modifies one RAM address per code.
Prior to releasing The Quiet Levels, I disabled the functionality of most (if not all) Game Genie codes by making their offsets obsolete within the ROM.

What do you mean disabled, i still can use this codes with znes and any modified room using the prince snes level editor, no problems, i have even tried invencibility when falling, to allow reach certain level areas for fun...

ZSNES also displays the meaning of the code after it was added.
Here is what I found out:
Code: Select all
1. 01:E9D7 $80 + 01:E9D8 $0A (Freeze timer)
2-9. 01:ED4B $NN (Start with N health points)
10. 01:CF83 $9C (Non-fatal injuries do no damage)
11. 01:AA52 $2E (Non-fatal falls do no damage)
12. 01:AA6D $02 (Non-fatal falls do 2 points of damage instead of 1)
13. 01:AA4D $80 (Falls do no damage--except onto spikes)
14-19. 01:8B4D $AD + 01:80A7 $NN (All enemies have N health points)
20. 01:8B53 $9C (Enemies drop dead immediately)
21-39. 03:9C3A $NN (Start on level N)

Yes, but remember, the offsets are written differently: 01:#### = x0#### and 03:#### = x1####
For example, "03:9C3A $NN" (Start on level N) becomes "x19C3A to $NN".
