Hi, I tried to do a quick search on Google, on the site and here on the forums, but I didn't have any luck.

Basically what I want to achieve is reading a few bytes from a specific address of the emulated RAM of the game (the reading is done from a little program I'm working on).
My idea was to read from a save state (quick to save for the user and easy to detect changes) but I noticed that on mGBA save states hava some kind of compression applied to them, so I can't use them in the intended way. I know about the memory viewer and the selection dumping feature but that's only manual and I was looking for an automatic one-keystroke kind of solution.

So my questions are:
Is there a way to make mGBA save the whole raw emulated RAM in the save state?

If not, is there a way in mGBA to make the memory dump process automatic?

If not, what are some possible ways (if there are any) to read the emulated RAM directly from within my program?
(I don't know much abot low-level stuff and memory access but if pointed in the right direction I can learn for myself no problem, I only need a starting point. Also I don't know if mGBA itself exposes some APIs for accessing it)

I can't seem to play gba games on my o3ds due to so much lag. I don't own n3ds and just use mgba for gb, gbc games which work great! I tried messing with some of the settings and didn't have much success any other solution?

I’ve been wondering if saving in game is preferred than saving on file? It’s because for GBA4IOS they prefer the player to save in game than on the gba app, soo which is it for windows mGBA? In game or on file? Both?

Hi! I have created shortcuts for my roms in Steam to play from big picture mode. Every other emulator works fine, but my mGBA shortcuts will only open the emulator, without loading the rom. This is how my shortcut looks:

Target: "D:\Emulación\Game Boy Advance\mGBA\mGBA.exe" "D:\Emulación\Game Boy Advance\Games\Castlevania - Aria of Sorrow (USA).gba"

Manually loading the rom works fine, though.

Any idea of why this might be happening?

Hola,

He instalado mGBA en mi new 3DS XL y el problema es que al emular un juego, no puedo ni subir ni bajar sonido ni tampoco se escucha nada, no puedo hacer nada con el sonido. 
¿Alguien tiene alguna idea de como solucionarlo ?

Muchísimas gracias por adelantado.

Seeing as Drill Dozer and Warioware Twisted have both shot up in price, I wanted to test rumble before making any purchases. However, I can't seem to get rumble to work no matter what I do. I've tried using both Windows and Homebrew on my Switch:

On Windows (7), I've tried:

• Enabling rumble via overrides pane
  
• Connecting my Switch Pro Controller via USB
  
• Connecting my Switch Pro Controller via Bluetooth
  
• Having Steam Big Picture open in the background
  
• Using WiinUPro
  

• Playing with Joycons in handheld mode
  
• Playing docked with Switch Pro Controller
  
• Using version 0.7.2
  
• Using the latest version (as of now: mGBA-build-2019-07-05)
  

as the title says is there anyway to have a shader have a transparent watermark?
the reasoning being
i want to see gba games that look like it was given the four swords adventures treatment

fsa used a texture to make two tiles that would otherwise look the same (eg two solid green grass tiles)
look diffrent

i want to do something similar but since i couldnt apply a static texture on always loading and unloading tiles
i figured a watermark with a transparent texture would be second best

While trying to rebind my keyboard for the game, i also tried to rebind the shortcuts. It works, but it barely shows the name of the shortcut. The settings window does'nt resize either, so I'm left guessing on what half of the shortcuts are since i can't see full names.

I have recently switched from no$gba to mGBA. I was in the middle of a game of pokemon emerald and I tried bringing my save file over but mgba doesn't load it when I load the rom, even though the .SAV file is in the same folder. I have tried "load temporary save file", but it didnt work. I'd be really glad if someone here knew how to make it work since it would suck to start over
