[BUG] R1\L1 buttons on RG353 [P/M/V/VS] switch a palette during saving\restoring progress in Gambatte when playing Gameboy games

[ihareg]

How to reproduce

Pre-conditions:

Use Rocknix or muOS on any handhelds.

Steps to reproduce the behaviour:

1. Use Gambatte emulator for Gameboy games (DMG) - in global setting.
2. Launch any Gameboy game with the Gambatte emulator.
3. Trigger Quick menu in the game -> Core Options (Gambatte) -> GB colorization -> Choose [Internal] and in [Internal Palette] any of palette.
4. Quit the Quick menu.
5. Try to save (SELECT+R1) or restore (SELECT+L1) a state of the game -> It leads to switching of a palette to previous one (L1) or to a next one (R1) in the list of Internal colorization palettes.

How to find key mapping for Gambatte in core settings:

Inside the Quick menu -> Controls -> Port 1 Controls:
L\L1 button -> Prev. Internal Palette.
R\L1 button -> Next. Internal Palette.

##Solution:
Clear a key mapping for the R1\L1 keys for Gambatte emulator. Leave them empty (---) as default config.
or assign them for R2\L2, because R1\L1 are used for saving\restoring in most handhelds.

Information

ROCKNIX Version: [e.g. 20250118]
Hardware Platform: RG353VS (any of RG353 or any other retro handhelds)

Context

It's quite annoying to change always a palette when U try to save\restore a state during playing GB games using Gambatte emulator and Internal palette.
The only solution: to remap keys in the settings to avoid it. BUT that will be applied ONLY to the current launched game, but not to the core settings at all.

Comment:

I've opened the issue for Rocknix, but they recommended to transfer it to this project: ROCKNIX/distribution#1307
