I use an acekard 2i on a dslite with an EZ Flash V Ram expansion/rumblepack. I initially used the 3in1 expack tool by Rudolph to access some gba games, and some games don't even need that to load and save properly, so I use 2 different folders to hold my gba files. Now I don't know if understanding what the PSRAM or NOR mode matters, but why does everyone recommend the GBAExploader homebrew software? I remember trying it once and it didn't work as well as the 3in1 expack. (I'm guessing this is the right section for this, I respect this site and community so I thought I'd sign up, go easy on me.
