Okay, I've heard people say slot-1/slot-2 can do certain things, and then heard other people say it can't do those things, it can do these things, etc. I am getting an r4ds, with micro sd Kingston 2GB - Made In Japan (Factory format), as it: -WORKS with Firmware 1.06 -Castlevania Test : 5 of 5 -No freezes in Castlevania Portrait of Ruin. But I've heard people say that a slot-2 is used for nds emulation, and gba, not the slot-1. But can the slot-1 use it too, or what does it do exactly? I'm confused on the whole matter... I want to get an ez4lite deluxe with micro sd as well, But i'm wondering which mirco sd goes best with it, or if I should even get one at all. I'd like the extra space. So, can r4ds micro sd kingston 2gb - made in japan (factory format), and an ez4lite deluxe (with micro sd maybe) do: -snes/nes/gb/nds/gba emulation (near flawless) -gba/ds homebrew emulation (near flawless as well) -dslinux support Please tell me. thanks.
