How does one use the cheat function if it's available?

I'm having some issues with some default settings with mgba, but these seem unchangeable:

the rom picker default recently got changed to "show all", but this creates a huge mess with all the other files.
I'd rather change it back to the old default: "show only supported files"

and I'd like to remap the in-game start/select buttons to X/Y, but while this should be possible with the game-settings it doesn't work because X/Y behavior is mapped to "game settings".

so is there any way to change these settings(show all/supported, and remap emulator buttons) on the 3ds version?

I just installed mGBA 0.4.0 on my N3DSXL via Ninjhax Homebrew launcher and while testing out Castlevania Circle of the Moon and Mega Man Zero, the sound has a lot of static and is pretty terrible overall. Is this a known issue or is there something I should be doing differently?

Thanks!

this is a bit of a strange request

but could the folders/files in mgba wii be sorted so the folders are at the very top ?
this is how almost all other wii emulators do it

I like this way because I have a lot of sub-folders in my roms folders (for hacks, translations, etc.), and rather than searching for a singular "hacks" folders amongst endless rom files, its nicer to just have it at the very top

thanks for the emulator btw, playing sonic advance smoothly on the wii is a dream!

Will mgba support gamecube controller adapter for wii u

When I click on File and other Stuff up the Top. The Game keeps playing and not Pause as I think it should

Can that be something Added to the Emulator?

I've had this issue ever since I first used mGBA a few months ago. No matter if I reduce the size of the image or tinker with the shader settings, I only get a corner of the screen rendered. Oddly, it doesn't happen with any other shaders.

Screenshot taken on 0.4, but as I said I've had this issue for months.

I might be getting one. It sounds like the team for it is working to have emulators run on it also. I'll see what they do with kickstarter this time around, I'd be up for getting endrift one,

Do I create a cheat folder or something? I thought this game had cheat support. There doesn't seem to be a cheat menu.

ive been running a newer linux os which runs and looks fantastic only issue is many emulators are still missing on it and need to be compiled or packaged. and MGBA is great but when i loaded a rom it was just audio the screen was black. not sure if its a problem with the emulator on Summon Night: Swordcraft Story as its not playable since i cant see a thing but it sounds fine and runs 100%
