Hi I am about to order some DS, and i just need to be certain that i am not wrong in the following: I can buy an retail DS (there comes powersupply with this right?) and without doing anything(flashing) i can insert the R4DS and play Nintendo DS roms? Another queston i have - there are many discussions about M3 or R4DS. But from what i have seen, it looks like i should go with the R4 because of the better support? And the last question some guys are recommending http://dealextreme.com/ or their great prices. Are they safe to order from?
