I just got a black DSL and am looking for a flash1 cartridge. I was going to get an R4 but I just say the DSTT's at dealextreme. Does anyone have one? The price is pretty awesome (and it comes with a rumble pack too ... even thought I probably wouldnt use it). Does it have anything that R4 doesnt have? And I've been reading around here... whats this "Neoflash" version of DSTT? Why are people asking if the the ones at dealextreme are Neoflash? Whats the difference if it is or isnt Neoflash? edit: also, I want the ability to play online (wi-fi) and be able to play games with other people if only one of us has the game (sharing?), can it and the r4 both do that?
