I’m on PsV, and my Pokémon Crystal runs just fine. But, when I try on Emerald, I can’t get cheats to save, load, or use. The lines are empty after I Add Line. Any tips?

So, since somewhat recently, every time I try to rewind in a game, the game usually crashes by accessing some incorrect memory addresses. This seems true for every GBA game I've tried.
It also tends to spew out some stuff about stub or illegal opcodes.
It seemed to work quite well before, but recently started breaking.
I'm on Arch Linux, so that brings a whole different mess there.
What should I do to try and remedy this?

I've recently downloaded mgba + a Pokemon rom hack called 'Pokemon run and bun'
Every time I open this ROM I get the following message on my screen:
Failed to open save file; in-game saves cannot be updated. Please ensure the save directory is writable without additional privileges (e.g. UAC on Windows).

How do I solve this issue?
I am using an Acer chromebook and I've downloaded it by using linux.

I am not good with laptops

Please help!!

Trying to connect to colosseum to trade via dolphin to my emerald but it says that the game isn't a USA version. I thought they were both USA but has anyone seen this or tried a work around?

Hi

wanted some help in getting mgba to trade with myself.

I previously thought maybe there was some kind of permission setting issues in macOS not allowing me to access the sav files, I've then realised that in the instance it doesn't grab it automatically, I can help it find it by loading alternate saves.

I'm now stuck in the section where it tries to link, any helps on this would be appreciated!

PS: the attached screenshot is the two emulator windows side by side.

Hi, thanks for this awesome job, question though. Is there any quick option for me to alter something to have this respond to both Analogue sticks for the directions. I can then play 1 handed on either side of the vita. I have seen in the config files to possibly switch from 1 to the other.

Through Virustotal scan

I'm playing through Inclement Emerald and I would like to have a different .sav file for each boss fight so that I can just change the file names to replay each one, but I can't see the .sav files or even the ROM file. The ROM file appears in the File Explorer and Start Menu as a "recent file", I can right-click to open the file location, and the mGBA app sees the ROM file and can play it, but I can't see the ROM or .sav in the File Explorer. I have the View settings configured to show hidden files, but that doesn't seem to have changed anything. Any tips on how to reveal my files?

Also I'm on Windows 11, if that matters.

Wondering if anyone has tried to take the GBA link cable and connect it to a PC usb port, then take the packets sent from GBA--->into emulator-->multiplayer, and vice versa?

Was going to try for "random" software coding practice.
Where do I find source code??>>

If someone has tried this, where can I find documentation?
Ultimate goal is to make a tiny link cable board that connects to wifi and uses emulators as host software for multiplayer.
Something like the wireless link, but modern.

Hi, I've been reading a lot about exchanging Pokemons in mGBA. I think I have followed correctly the exact instructions which are:

- Open the .gba main game in mGBA window1
- Open a multiplayer tab an load the same ROM or a copy of it
- Go to a Pokemon centre and select exchange Pokemon in the upper part of the building

It then says wait for connection in both tabs and does nothing, I do not know what else I'm suppose to do, so I am seeking help in this forum.

Any tip will be appreciated, thanks.
