What's the problem? Describe what went wrong.

I was working on modifying one of the AR codes for this game, particularly the built-in RD-Pad Left/Right Controls Time (Twilight Spectre). The exact AR code in question is
0A3DD31A 00000022
844061F4 00003800
0A3DD31A 00000021
844061F4 FFFFB8FF
When running the built-in code, everything works fine and as intended. The problem arises when this code is copied into a new AR code, staying completely unchanged with nothing added. Upon running this code, the game freezes on startup (purple screen) and an error occurs [see first image attached]. It seems that 844061F4 (which should be incrementing 0x804061F4) is not working as intended (instead reading from 0x814061F4 ?) even though it should not run until either conditional (0A3DD31A) is met. When isolating the second line of the code into its own code, the game also freezes [see attached #2] with a different error. All of the previous was tested on the first device listed below (Android).

When tested on the second device below (Linux), I could not get either the built-in or copied code to function at all, although there were no freezing/crashes.

I wouldn't be surprised if something with the 84xxxxxx code is the root of the problem, but the why is beyond me.

What steps will reproduce the problem?

-Copy code from above into a new AR code
-Activate Code
-Start Twilight Princess (GZ2E01)
-Nothing is shown but a purple screen and an error message on startup

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Unknown but very likely. Dev version APK does not install when dolphin has already been installed

Is the issue present in the latest release? For future reference, please also write down the version number of the latest release.

Yes, Version 2409

What are your PC specifications? (CPU, GPU, Operating System, more)

Android 13, (Motorola Edge 5G UW 2021)

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
