I have a couple of questions, searched around, but can't find a clear answer. I'm looking to get a flash cart for my phat ds to go along with my R4. I've heard the 3-in-1 is the best as I can use NDStation to store the ROMs on my R4 and flash them, but I've heard/seen the 3-in-1 doesn't fit in the phat DS. In that case, is it possible to use the EZ Flash 4 with NDStation? I also have an SP and was wondering if the EZ4/3-in-1 would be compatible with it (I believe it is but am not entirely sure) and also want opinions as to whether I should order another EZ4/3-in-1 for my little bro's SP (he doesn't have a DS, but I still hear the EZ4 is the best for GBA). Thanks.
