Multiplayer Window Cannot Load Save

[D28]

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.

Each multiplayer window has a different save file so they don't trample over each other when different games save. First player save files are .sav, player 2 is .sa2, player 3 is .sa3, and player 4 is .sa4.
