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?
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.)
