Now, I know that the 3 in 1 expansion can only have 1 GBA game loaded on it at a time, but my question is, can I switch games and keep my save files, like on my slot-1 device or something? I'm using an R4 as my slot-1 device, btw.
Narin said:I suggest getting the GBA Exploder (The newest addition of Rudolph's 3in1 Tools) which work on both the new and old 3in1 devices and contain more features and bug fixes. It also has support for more slot2 devices than just the 3in1 as well.
