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.

That's how mGBA 0.10.5 handles multiplayer saves: each window has its own file. The main .sav file doesn't update automatically in multiplayer; you need to manually merge or export it. Newer versions handle this better.
