Hey! Just posting wondering exactly how to enter cheats on mGBA 3DS. I can find codes online and have tried entering them, but haven't had any success. Also tried downloading a cheats file to my sd card and could not find a way to add the file to mGBA. When I add a cheat set do I enter the cheat code there? Or in new line? New line seems limited on characters for cheat codes. What type of codes does this accept? Thanks in advance, just can't find a lot of info on this.

The GBA game 'Sangokushi Eiketsuden' is a tactical RPG like the Fire Emblem series.

As you can see from the attached image, when a character attacks, face images of both the attacking and defending characters appear, but those images aren't displayed properly.

(I also attached the savestate file from right before it happens. If you press the A button, it occurs.)

This error isn't caused by a corrupted ROM file or emulator settings.

I checked multiple ROM files of the same game on a real NDS(with GBA compatibility), and all the ROMs worked fine.

I also tried many other GBA emulators, and all of them had this problem except for gpsp.

So I'm pretty sure it's an emulation problem.

How can I report this to the developers?

Hi, I'm playing Pokémon FireRed on mGBA 0.10.5 on my mac(macOS26.0.1). I created a “multiplayer window,” but when I tried to use the in-game save on my first window — the .sav file doesn’t update (the “Date Modified” still shows yesterday). Only the second window generates a .sa2 file. I don’t know why this is happening or what went wrong.

Hello,

Simple question, I have a savefile from open_agb_firm on 3DS and I want to put it on my Switch. I can't find an option for this, and putting the savefile next to my rom (same name) didn't work. Could someone please point me in the right direction?

I am pretty far into Fire Red, I wanted to spawn in a Golmen, Machamp, Gengar, and Alakazam to complete the pokedex since they are only attainable via trade. I had started with the max money cheat to test the cheats, but it could not get any to work. Need help. I'm on windows download mGBA.

I'm trying to move over a 2 save files from gambatte for use with mGBA (I want to do multiplayer trading). The save files were generated in retroarch/gambatte on an anbernic device.

I'm trying to get them to run in standalone mGBA 0.10.5 on my Windows PC.

I'm fairly new to ROMS so been having to do a lot of Reserarch/experimentation but I managed to get one of the 2 games working. I was unable to copy and convert the save file from my anbernic, so I had to copy the state file to my PC, load that into retroarch/gambatte, create a new save file on the PC in that, then run that through a srm to sav converted.

My second game however, nothing seems to work. If I do the same as above, the game freezes when trying to load the file. using a transferred state file, I got the state loaded on the pc using retroarch/mgba core. However the sound is glitchy and when I create a save file, it still can't be loaded into the mGBA standalone.

Any guidance on how to fix this is appreciated.

Hi, does anyone else have an issue with assigning keys to L & R on controllers?
I have Retrobit Legacy16 Wired USB Controller and the L & R is not being picked up when assigning keys.
It does pick up the LZ and RZ buttons, but not the big L & R ones.
If anyone has a solution, please advise.
L & R work fine on other emulators.

im confused on how to convert my sa2 file to sav

Windows 10, 64-bit
The rewind button seems to crash the game and the emulator with the "jumped to an incorrect address" error on the regular version of mGBA.
On the 64x version of mGBA, however, the rewind doesn't seem to function at all, no matter how much I press the button I assigned or change the controls.

This is on the latest version of mGBA I got from the site - 0.10.5 - but the older one I had before - 0.10.1 had the same issue.

Is there a solution to this?

Hi,

I am somewhat new to GBA dev, I only ever touched features mentioned in the TONC tutorials.

I would like to use the serial port to communicate between my ROM and the emulator. Is it possible with mGBA ? Do you have any reference on how to do it ? I would assume it requires using the Lua scripting capabilities.

Thanks !
