Topic. Need a replacement cart. I know that the DSTWO has an onboard processor, emulates GBA games, media player, etc. AK2i is cheap. Am I missing anything? What's the feel of each cart? Which should I buy for my 3DS? I don't expect to do much GBA emulation (I have ambassador and emulation will kill my 3DS battery). If I get the DSTWO and use it only for games, will the battery continue draining at an accelerated rate? Yep, it's been a long time since I've had to ask about flashcards.
