Walk through walls

This tutorial can be achieved on real hardware, or on mGBA emulator using an original (dumped) GBA bios. Other emulators might not be accurate enough.

Tutorials in this section are only for USA/European versions.

The bad eggs created in this tutorial should not be marked or moved in your party: it could corrupt them.

This script will allow you to walk through walls (however it does not allow you to leave the bounds of the map). In order to enable it, it must be executed each frame by using the freezer bad egg.

Prerequisite

A stable ACE glitch species (with its Thumb->ARM bootstrap if needed)
A certificate exit code bootstrap (you can place it in the first slot of BOX 14 for instance). Note that it does not matter if you have renamed your BOX 14 as the creation of this bad egg uses the hexadecimal-writer bad egg
The hexadecimal-writer and crafting table bad eggs
The freezer bad egg with the registry-saver Metapod extension

Let's go

We will use the hexadecimal-writer bad egg in order to write the script in the PC storage. You should ensure that your freezer bad egg will not be executed instead of the hexadecimal-writer (in order for it to not be executed, you can put it either somewhere in the crafting table area or before the last row of BOX 11). Also ensure that there are at least 3 empty slots at the beginning of the crafting table area, and run these 4 codes without looking at BOX 12 (or where your crafting table area is) between the execution of the codes:

=============== CODE 1 ===============

Box  1: 001F2DE9
Box  2: 88A09FE5
Box  3: B2C1DAE1
Box  4: BCB8DFE1
Box  5: 000000FF
Box  6: B4C8CFE1
Box  7: 0B005CE1
Box  8: 80A09F05
Box  9: B0B8DF01
Box 10: B0B0CA01
Boxes 11-14: 00000000

=============== CODE 2 ===============

Box  1: 68A09FE5
Box  2: 00B09AE5
Box  3: 64C09FE5
Box  4: B081DCE1
Box  5: B291DCE1
Box  6: 18C0DCE5
Box  7: 11005CE3
Box  8: 01908902
Box  9: 33005CE3
Box 10: 01804802
Boxes 11-14: 00000000

=============== CODE 3 ===============

Box  1: 22005CE3
Box  2: 01904902
Box  3: 44005CE3
Box  4: 01808802
Box  5: 000000FF
Box  6: 08A09AE5
Box  7: 88A08AE0
Box  8: 990B09E0
Box  9: 89A08AE0
Box 10: 28A08FE5
Boxes 11-14: 00000000

=============== CODE 4 ===============

Box  1: B0B0DAE1
Box  2: B4B2CFE1
Box  3: 03CBE0E3
Box  4: 0CB00BE0
Box  5: B0B0CAE1
Box  6: 001FBDE8
Box  7: 10FF2FE1
Box  8: 18730302
Box  9: C05D0003
Box 10: 50730302
Boxes 11-14: 00000000

After that, there should be 2 bad eggs at the beginning of your crafting table area.

Now, move the freezer bad egg in the BOX 14 slot 3 (or anywhere at least 2 slots after the exit code bootstrap) and move these two bad eggs just after (don't change their order).

Execute the ACE... and the walk-through-walls mode should be active. Just execute the ACE again to disable it.
