How do I change the resolution or window size when in fullscreen? Actually I am using retroarch so the program only uses core files from mGBA meaning I don't know how to change anything. I use my tv as the monitor but my tv is old so there are parts that are cropped off while fullscreen. I'd like to resize the screen so that it's just a LITTLE smaller if possible.

Hi,

I've been looking into the benefits of VC injection for GBA backups rather than using emulators.  Obviously it works better for some games than others (for example, SMA4 or the Pokemon titles requiring a lot of messing around with hex patches etc, and even then not functioning properly).  I have an N3DS, and the framerate in mGBA is just fine (as is sound in the latest nightly), so the only real benefit from injection is having shortcuts directly to games on my home screen - which is the only real feature that I care about.

Is there anyway to create a .cia file that could call mGBA to start and stop with a specific rom?  (ie, the cia is executed and starts the cia version of mGBA with a call that loads a specific ROM, and then when the emulation is stopped mGBA auto closes).

Alternatively, how tricky would it be to build a cut down 'wrapper' version of mGBA that is either hardcoded (or uses a config entry) to start a ROM at launch, and then close when the emulation finishes?  I appreciate that this would require multiple mGBA installs (one for each game) but mGBA is pretty small, and I have a 128GB SDXC with plenty of room to spare.

I'm looking for ways to get those last few tricky games onto my home screen without using injection, as mGBA seems to provide much better compatibility in some cases (and more options are good!).

I'm not necessarily looking for anyone to do this for me - I'd just really appreciate some pointers.  I have done some limited development in the past (for personal use rather than professionally) so I may be able to have a crack at this if I know where to start.

(On the other hand, if anyone more experienced wanted to weigh in with the code I'd be happy to test).

Thanks for reading (and hopefully chiming in!)

Hello, for starters i'd like to say thanks for making this amazing emulator, i'm really enjoying it and hope it will keep up being the best.


So i'd like to make a suggestion of implementing a feature for mGBA ala BGB where you can use a png image as a frame to the emulator and make it look like the pic below.
I imagine maybe i'd use a frame from the Game Boy Advance player for the Gamecube..taking in account the resolution of the screen as you can do with BGB!
Thanks!

So this emulator has been amazing and I love it but recently I messed around with my settings I don't remember and now the fast forward feature does not work. When I either hold Tab or press Shift+Tab the game plays at normal speed but the audio is distorted. I deleted the files and the appdata files as well and unzipped the download files but it's still broken. It's not just one game either it used to work on Fire Emblem(The game I use it for), Zelda minish cap, Metroid Fusion and others.

I'm on  my laptop, Windows 10 64-bit, Intel Celeron quad core processor n2930, Intel HD Graphics. I use version 0.5.2

Could someone please give me step-by-step instructions on how to activate gameshark cheat codes on this emulator? I have yet to find a thorough explanation. If one exists, could you provide a link? Thanks

I did notice it was planned (No rush, really!)
But I was also wondering if it'd be ported to the homebrew versions? If that was possible, anyways, would be cool to have a 3ds with a GBA game running connected to Dolphin!

There're other threads like this, but I'm 100% lost.

I'm trying to get a feebas cheat (where every pokemon that spawns is a feebas)

I've tried the method in one of the other threads, where I added it as a pro action replay, and I'm certain I'm using the right codes... so why won't a feebas ever spawn? Is it something wrong with mGBA or am I just really stupid?

EDIT: Site where I'm getting the codes from; https://www.supercheats.com/gameboyadvan...ll-cheats/

Greetings!

After equipping my own New 3DS XL with the latest CFW and Luma3DS recently, I got in touch with mGBA and was, like many others before me, intrigued by the quality of this emulator!

While the video performance is nearly perfect on my device, there seem to be some issues with the quality of the sound output: I tried to play one of the Golden Sun games and immediately noticed a strange behaviour with certain, deep sound effects and music.
Since the Audio is flawless when trying out the game on Windows, I am trying to figure out if there is some way to improve the quality to the same standard on my device.

I made a recording of the current sound situation; if someone finds the time and the energy, I am happy for any advice or hint that anyone can give me here:

If neccessary and/or possible, I should also be able to adapt some internal parameters within the emulator's source code and create a new .3dsx binary for testing.

Many thanks in advance,
and so long,
Max

Hi, I want to know if it is possible to:
-Link with another person with mgba for homebrew 3ds
-Export save files to another emulator with mGba for homebrew 3ds
If it is not possible, can you add it in a future version?.
Thanks for your attention,
Fernando
P.D: I´m refering about pokemon games (Crystal, yellow and emerald)

I just started using mGBA on my homebrewed Wii, and while I'm very happy with how smooth it runs games, I'm kinda bothered that I can't get it to display in the correct aspect ratio. It's too wide in 16:9 mode, and too skinny in 4:3 mode. I also want it to fill as much of the screen as possible, so I don't like Pixel Perfect mode.

I've tried adding "stretchWidth=.9stretchHeight=1.0" after [ports.Wii] in my config file like other have suggested, but it doesn't seem to actually do anything. Am I doing something wrong?

Also, Is it possible to transfer saves from the Wii version of VBAGX to mGBA for Wii?
