Pokémon emulator self-trading issue

[Phorrest]

Hi! I am playing Pokémon Crystal on mGBA emulator. I opened a new multiplayer window to self trade with my Pokémon Gold rom. However, when I try to initiate a trade on both windows, it says “your friend is not ready.” I mapped the second window to a controller and pressed the buttons at the same time but still nothing. Does anyone know what I might be doing wrong?

Write here: https://github.com/mgba-emu/mgba/issues

Thats will help remove the bug of emulator of course if you have that in new version otherwise you can also try latest one:

https://github.com/mgba-emu/mgba/releases

One more thing saves in old emulator are incompatible with new one.

Also do you have patches in both roms?

@Phorrest

 

[Phorrest]

What are patches in roms? sorry I'm a bit new to this... Also, is downloading the release of mGBA in the link the same one that is posted on their website?

@Phorrest Patches are fixes of games also used for hacks.

Yes from his website programmer of mGBA is called endrift.

Patching a rom is process of editing files.

Ok I’m that case, I do not have any patches in my rom and I uninstalled and downloaded mGBA again and I am met with the same message

@Phorrest Do you have latest version 0.9.3 ?

You can also try downgrade to older if not work in latest.

 

[Phorrest]

@pix07 I tried to downgrade but no luck. Do you think it could be a problem with the rom? I got both roms off of Vimms lair.

@Phorrest They are bad dumps ?

Verifited roms have [!] sign here more info:

You need :

[!] - Verified Good Dump

Bad dumps usually have bugs.

 

[Phorrest]

@pix07 it says that it is a verified rom but I’ll look more into it later

@Phorrest Did you post your issue on github ?

And there is other gameboy emulator called bgb.

http://bgb.bircd.org/

Most important from that emulator:

SGB multiplayer with up to 4 gamepads

Also this:

http://bgb.bircd.org/bgblink.html

bgb game link works over TCP/IP. one side listens, the other side connects. When the initial handshake is complete, until the connection is broken, a plugged in link cable is emulated.

As far as I know, it is possible with the paid version of the app; I'll check it for you in a moment...

So it appears to function similarly to GBA emulation. In that case, take a look at this. (It's specifically about how to trade between two instances of the same game to obtain trade-exclusive pokemons; however, instead of launching another copy of what you're currently playing, simply launch another ROM.) (Oh, and it's also important, at least for me, to have savestates in both games before trading in case something goes wrong) (and, obviously, save both games afterwards, not only one)
(Also, if you don't need to load from savestates, you might break your clock.)
