mutiplayer saving not working(mGBA0.10.5, macOS26.0.1)

[freeifly]

Hi, I'm playing Pokémon FireRed on mGBA 0.10.5 on my mac(macOS26.0.1). I created a “multiplayer window,” but when I tried to use the in-game save on my first window — the .sav file doesn’t update (the “Date Modified” still shows yesterday). Only the second window generates a .sa2 file. I don’t know why this is happening or what went wrong.
