I recently downloaded mGBA, really liking it.

However, it appears that whilst I can open and play a ROM on an opened multiplayer window, I cannot load the associated save. Does anybody know of a solution?

Thanks.

I need help regarding my save data that I have it's not a save state its a .sav file and no matter what i do it wont load and just keeps making me restart my game

Hello! I recently made an in depth issue, or I guess... A desperate attempt at asking for help on Project Pokemon, and here's the forum I made that incorporate's mGBA, and the main issue is mGBA.

https://projectpokemon.org/home/forums/t...emulation/

But in short, I'm using a GBA ROM that can allow a transfer between any 1st or 2nd generation of pokemon to the 3rd generation. Using real hardware, this is completely possible, with only needing a Gameboy Color link cable, but that's the problem.

mGBA doesn't specify which link cable to emulate, and seems to default to a GBA link cable. I specifically need both multiplayer windows to use a emulated Gameboy Color cable instead. How easy is a add-on to mGBA that allows Gameboy link cable specifications, and is it possible?

The creator of the said transfer ROM states that a middle-man program that emulates the Gameboy color cable instead of the GBA link cable that connects to mGBA would clunkily work too, and would that also be possible?

I recently started playing a game of Pokemon Emerald Version on my 3DS running CFW. I created a Virtual Console game of Pokemon Emerald Version using New Super Ultimate Injector and used the save type "Flash 1Mbit (Macronix, ID: 0x09C2) + RTC" to create the .cia. After playing for a few day, I dumped the .sav onto my PC and ran it using mGBA in order to trade Pokemon with myself on another rom. Everything was going great until I tried to inject the .sav back into my VC game of Emerald on my 3DS which gave me an error. After troubleshooting, I discovered that mGBA adds 16 bytes of data onto the end of the .sav to keep it's RTC. Once I discovered this, I was able to edit the data by removing those 16 bytes which allowed me to successfully inject the .sav back into my VC of Emerald.

Fast forward 2 IRL days and I've noticed that my berries aren't growing, but they were growing just fine before I used mGBA. Using PKHex I was able to see that my RTC had not progressed in 2 days. I figured it was the missing code and upon rebooting the .sav in mGBA, the berries have grown and opening it in PKHex shows that the RTC has progressed again.

The issue now is that I cannot inject the .sav the way it is since it has 131,088 bytes of data and it must have exactly 131,072 to be injected back into my VC running Pokemon Emerald. Removing those 16 bytes allows me to inject the .sav but the RTC is disabled which disables many important functions of the game. Sadly, the .sav file is missing data that it not need before.

I have tried checking the "Reset RTC" flags in PKHex does not progress the RTC either. I see my only options as restarting a new game and never touching mGBA again (regrettably) or continuing to play the game on an emulator on my 3DS (which sadly does not run as smoothly or seamlessly as a virtual console title).

Given these symptoms, does the community have any ideas as to what I could try to do to fix my .sav and make it work properly again? I have included my most recent .sav without the 16 bytes that mGBA added. Running it through mGBA makes the RTC work again, but the real solution would be for mGBA to not add these 16 bytes to the .sav in the first place and to emulate an RTC itself.

I'm trying to create a Lua script to alter keys in the midst of gameplay (specifically for the game Kingdom Hearts - Chain of Memories), but I can't seem to get any of the Lua scripts to work at all. I downloaded some from the GitHub repo and loaded them in the `Tools -> Scripting` window, but if I try to run them while a game is playing they'll throw errors like "attempt to index a nil value (global 'input')" for `analog-interpolate` and `gamepad-demo`, or "attempt to index a nil value (global 'image')" for `color-mask`.

Is there something I'm missing here, like a script you need to run beforehand to set up these global variables, or am I only supposed to run these against an example ROM or something? I've tried for over an hour now to find documentation, but all I can find is the Scripting API and the example Lua snippets. Would greatly appreciate any help or advice.

I have mGBA and the game's ROM under C:\users\[my computer account]\Downloads, and while playing I saved my game to one of the game's built-in save slots and to two different savestates. The files are indeed there in the game's folder, and are not empty. However, when I open mGBA, loading the ROM will act as if it is my first time playing, and my saves are not there when I open the dropdown menu at the top of the emulator window.

I am thinking this *might* be an issue with the saves being in the wrong folder, so I ask where the saves usually are? I know they should be in the same folder as the ROM, but I don't know where exactly that folder should be in relation to the emulator's own folder.

As the title says, my keyboard shortcuts are not working. I’m playing Pokémon Ruby. I can walk and press A/B, but I can’t fast forward or take screenshots and stuff like that.
Also, how do I restore keyboard shortcuts to the default?

Hello. I would like to know if there is any way to legally get roms, such as all the third generation Pokémon ones. And I would also like to know how to get a GBA BIOS.
Thank you for your time, regards

This might be a stupid question but how do I fix the following error:

"Please check whether the Wireless Adapter is connected properly and turn on the power again."

This is happening when I try to load a Pokemon Fire Red rom.

I have had the same error on 3DS mGBA and MacOS mGBA.

Image attached.

Thanks,
F

Hello everyone.
First of all, forgive my English, I use a translator.
I want to know if it is possible for two people to play Pokémon at the same time.
I've been trying to configure the buttons for each window, but only the window that is selected moves. And if I use a Joystick (XBOX Series Controller), it moves the game in both windows at the same time. Is there a way to set this up so that everyone plays their game at the same time?
Greetings and thanks.
