fixed reversed X/Y buttons in drastic-trngaje on the brick

[xikteny]

The TrimUI Brick's X and Y buttons are reversed in drastic-trngaje. Both their in-game functions (e.g. pressing the hardware X button presses the Y button in-game) and their in-emulator functions (e.g. pressing Menu + Y opened the emulator menu, instead of the intended Menu + X) are reversed.

This fix simply swaps all references to the hardware X/Y buttons in the device-specific drastic.cfg, restoring proper behavior. This fix was tested in muOS's current version of the core as well as with a manually-updated version from https://github.com/trngaje/advanced_drastic/releases/tag/libadvdrastic . X/Y function was confirmed using a test ROM as well as the emulator menu hotkey.

Possible concerns:

• Do controls_b[CONTROL_INDEX_UI_BACK] and controls_b[CONTROL_INDEX_UI_PAGE_UP] even work? It kinda seems like they don't, for me. I swapped them anyway.
• I also attempted to test this after manually applying Update Advanced Drastic emulator to the latest build (v2.5.2.2) extra#46 , but I was having trouble getting that version of drastic to actually work. Probably not really relevant to this issue.
