Hi everyone!

I’m having trouble trying to start the VS mode of Tactics Ogre: Knight of Lodis on mGBA.

I use the "New multiplayer window" function to launch a second instance of the emulator. I load the ROM in both instances and start the VS mode from two different save files. However, the two emulator instances don’t seem to recognize each other…

Do you have any suggestions?

Thanks a lot in advance to anyone who replies.

Hello, I foolishly loaded my near completion gba game file in mGBA. I typically play the game on my ez flash cart but in trying mGBA it split the file into the base game and a “.sav” file. Effectively ruining the game for both. Can anyone point me in the right direction to fix this please? This is all I play.

Why does it make these sounds when I load up the bios in mGBA? it works fine in other emulators.
here's a link to the video, since it doesn't allow me to attach a video: https://file.garden/ZiXiiiIWlR7-wknI/mGB...-11-24.mp4 (idk if links are allowed, as I couldn't find a rules page for this)

I'm playing a Emerald based hackroom on multiplayer and the second player can't save without freezing both layers. I have try differents config and a dev build but i couldn't fix it

As I use GlosSI to make mGBA to work with steam input. But ViGEmBus is now unsupported program for Windows 10 and 11 and there are no alternatives. So I'm stuck with using mGBA on retroarch and I added non-steam windows retroarch to steam library to use with steam input with various of my controllers like NSO snes controller for Nintendo switch. Retroarch doesn't have hi-res mode for mGBA but I can't use mGBA exe program because steam input doesn't work with it.

Steam input works for duckstation, pcsx2, dolphin, retroarch, mame and rpcs3.
It doesn't work for mGBA and melonDS. Azahar 3ds emulator are also fixing this bug.
I also have to use melonDS through retroarch as melonDS exe program doesn't work with steam input.

Hey Guys, my new Controller arrived today and I have huge mapping problems with it
with my PS4 Controller, everything was nice

A lot of inputs give the 2 inputs at the same time and I cannot delete some of it at all. Leading to problem with multiple inputs at the same time.

The analog Sticks aren't working at all like intended
Doing a “left” input with the analog stick results in a “R1” input, and deleting the analogs does nothing.

The Controller features 4 Modes

x-input (right now)
d-input
switch mode
apple mode

In another mode, I guess D-input (not sure) I had an issue with pressing “L3” resulted in walking leftwards and “R3” resulted in walking rightwards.

I use a controller for mGBA and the emulator supports inputs even when I'm not tabbed in. Is there a way to also allow shortcuts to also do that? I sometimes use an OBS window for an overlay and need to tab back into the regular emulator window to fast forward, which gets pretty annoying after a while.

Hello, I've been playing pokemon emerald, but my save file got all of the save states wiped for apparently no reason. File seems way too light to hold any info about my games. Happened with no cause, I just loaded into the rom and the save states were gone. Anybody knows how (or if) I can solve this and get my old save back?
Please, it would mean a lot to me if someone could help.

Hi All,

Love mGBA, but I hate how 640x480 retro handhelds make GBA games look. It's either uneven or blurry, or both.

With millions of people playing GBA games on such devices and screens, I think we could do a better job.

I used to be an embedded game dev for over a decade, so I came up with a simple but elegant scaling algorithm, that is consistent and retains the sharpness without uneven text.

I'd love to integrate it to mGBA, if possible. It'd be a very specific scaler for the 240x160 to 600x400 scaling only, although I could generalize it to be useful for 2.5x, 3.5x, 4.5x scaling the same way.
Would this be okay to implement here? If so, where in the architecture would it fit best @endrift?

Here's a simple .js implementation and some samples:

Cheers,
Peter
