i know this has been stated in the sticky, but if you intend to use a 3DS for DS Flashcarts, DONT! 3DS is a horrible way to play DS Games. for one thing the display is stretched out to fit the higher resolution of the 3DS, so DS games look blurry and washed out. and if you set it to the proper resolution by holding SELECT, then it displays the same size as a DS Lite / DSi anyway. thinking about the Analog Stick? think again. it still only registers 4-directions, DS is Digital control only. so there is really NO advantage to using it over the D-pad. and actually its even WORSE, Super Mario 64 is impossible with the slider pad, (i could not get the chain chomp off the leash after hours of trying), and even if you wanted to use the D-Pad they moved it down so far its now uncomfortable to access. not trying to advertise, but dealextreme has DS Lites for $66. yes they are probably refurbished but they are 1:1 exactly the same as a brand new model from Nintendo. And if you are electronically inclined you can just buy the parts from DX and refurbish an old DS Lite yourself for next to nothing! personally i like both DS Lite and DS Phat, theres really not much difference between them, anybody that says one DS's screen is better is just a DS Snob or being picky. DS Phat works fine on brightly colored games like mario kart or clubhouse games. What about the DSi XL? 1. theres really nothing interesting on DSi ware. 2. even the larger DSi XL screen is still the same resolution just stretched out, DS Lite looks way better because of this, and you dont have to worry about updates blocking the flashcard, and it loads without the DSi menu, and you have in-game brightness adjustment, AND it plays GBA games, AND it supports Slot-2 peripheral like Guitar Hero controller, arkanoid paddle, Rumble Pak, etc. AND you can use a DS lite to update flashcart firmware, or switch your Cyclo DSi into DSi mode. DS Lite is like a swiss army knife of DS's, it does everything! i have a beat-up old DS Phat and i use it just as much as my 3DS, for testing new homebrew so i don't wear out the buttons on my good DS, and if a game freezes its easier to get back to flashcart menu. or just as a guest controller, if you have a friend that's particularly irresponsible or has Cheeto-stained fingers, just hand him your old Phat and play some mario kart DS.
