Nice.
I only have three flashcarts — EZ-Flash IV, EZ-Flash 3in1 and Supercard DSTwo.
I lost the 3in1 a while ago, but found it at the place I would have least expected it to be.
I got my R4 from some eBay-ish site. It was risky with what it was, but sure enough, the cart shipped out of China (I could tell easily by the packaging) and was in brand new condition upon arrival.
Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.
@Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.
