I probably opened an issue describing this situation before, but it turns out that I still can’t write GT2 saves properly. Every time I write these saves, the game will fail to load them, and when I read them back once I wrote them, they do show some differences from the original file when comparing them with an hex editor.
Does it have to do with how big this save file is compared to others? This is in fact the only save file that I can’t copy properly.
I am using an official memory card.
