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,

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.

I've been using mGBA for a few years now and I like to use save states alongside the actual save because saving to the .sav file does not always work.

This method and save states have been life savers on some occasions and I have never had a problem until now.

I am playing Pokemon Scorched Silver and out of nowhere my save state corrupted.

It seems to be just the state in the first slot and I have another state in the second created from the last position the actual save was on BTW which did not save where I had the corrupted save state, this is the reason I use both.

Fortunately, all I really lost was almost 1.6k coins from spamming the roulette in the Goldenrod Game Corner but that is still a lot of time I spent for nothing.

Is there a way to fix a corrupted save state?

how do I set the max rewind frame memory to more than 3600 frames history? i had it going back a lot farther than that, but something happened to my comp and now I can't get it back past 3600 frames. I want to set it to like 9999 if I can, or however much the absolute max is

Hi, I'm trying to use pkhex on my rom hack and there's a problem. Every MGBA .sav has some sort of computer timestamp at the end which makes it impossible to load into pkhex without deleting it. See here:

I saw this post that I thought could help, which talks about game overrides: https://www.reddit.com/r/pokemonrng/comm...are_button

I may have been able to export a save without this filler data at the end once, but I definitely have not been able to do so consistently. I never had this problem on my mac, and I'm just now on windows. I tried using the old version of mgba (0.9.1) on windows which didn't do anything, I tried the portable version and the normal installable version and all of these emulators consistently add the junk data at the end of the .sav which really annoys me. Is there any way to consistently have mgba stop adding this extra save data on my windows computer?

I never ever had this problem on my mac. I've tried unchecking the autodetect option and enabling realtime clock with all sorts of save types and nothing has worked. Deleting this filler data at 0x20000 always lets me use pkhex.

Thanks!

I'm playing a modded version of Yu Gi Oh: Reshef of Destruction, trying to duel myself to cheese the benefits. I load the rom, select open multiplayer window, and have 2 instances of the game running at the same time, Player 1 and Player 2.

Once I do this, the original instance loses access to all save states (although it does use the correct game save info). Also, the 2nd instance has no access to the save data from instance 1. My only option is to start a completely new game, so I figured "ok fine, I'll just play through the intro and then save". Problem is, now I'm scared to close out the programs because I don't know if I'll have to start a new "player 2" file and replay through the intro every time I want to do this.

Also I can't find where the save data for the game is, otherwise I might have tried to do something with the "pathing" settings. Tbh it seems like all the save data is just wizarded out of nowhere, because I can't find any kind of save data anywhere in my file explorer.

Is there a way to have player 2 load the same save file as player 1 and play against myself? What will happen if I close the program; will I have to make a new profile for player 2 every time because its the same game, and they can't both play off the same save profile? Should I make a 2nd copy of the ROM and alter its name to "Reshef 2nd profile", save that game after playing through the intro, and load it in the "player 2" multiplayer window that's generated from the original game's instance next time I try to do multiplayer? Bottom line, whats the best way to set things up so I can just quickly give my main character a throwaway player to easily beat and cheese goodies from the duels against myself?
