FearLess Cheat Engine

Hey Guys iam stuck with a problem.

i made a table for the GBA Pokemon Romhack Pokemon Unbound. It is based on the Fire Red Edition.
I want to add Walk Through Walls Cheat to my table but iam not able to find a solution for it.

The have tried the following so far.

• Searching for 0 for normal walking an 1 for walking against a wall.
  • No luck

• Searching for unknown value while standing and then walk/stand normal or walking against a wall and search for changed value
  • this brings up some addresses
  • searched what write/accessed these and tried to nop the routines, which leads into nothing or a crash

• Searching for X Y Values
  • Found multiple addresses
  • searched what writes/accessed, nopping, changing, freezing
  • some leads to walking a little out of bounds, freezing the game or reshape the map

• Searching the Input and reading through the assembly to understand whats going on
  • didnt find anything related to collision

• Tried Ultimap, for walking into wall the code is executed and for walking around / standing code is not executed
  • Got some result but nopping them did nothing or freeze the game

Then i try to find out what the Gameshark Code for FireRed does, to understand how its done there, but i didnt find any information about it.

I hope anyone have an idea what i could try next.

Greetings and thank you
