Currently, my 6 year old son has a DSlite with an Acekard 2i. He's a big fan of Mario, Kirby and Zelda games. I like our AceKard 2i, (with Akaio) except for: 1. The SNES emulator I have on it requires a lot of 'babysitting' with the settings. He's only 6, and even I have a hard time getting the settings perfect. 2. There is no way to play GBA games. I'd especially like to run all the Super Mario Advance, Zelda, and Kirby games available (in order of priority) 3. I am having trouble getting Phantom Hourglass to work on it. (that's not a big one, but it would be nice if it worked. I've tried several different ROMs) I was thinking of buying either a DSTWO to replace our Acekard 2i (and using it for the SNES and GBA emulation) or just buying an EZ Flash 3in1 to run the GBA games off of. I do understand that the Mario Advance games pretty much cover Mario 1-Super Mario World. So if that is something to take into consideration as well. For instance, I might get by with just the EZ Flash 3in1 and not buy the DSTWO. I guess I had a few questions and if anybody has any other insight, feel free to throw some in. 1. Will the DSTWO GBA emulator play all the Mario, Zelda, and Kirby games. I know there are compatibility lists, but some of them seem to differ on some of these games (or they are not listed). 2. I've heard there's an issue with saving the game "in-game". It's recommended to do a "save-state". I'm not sure if this will confuse him or not.... probably. Is the "in-game" saves a problem for all games? 3. Is the interface too confusing for a 6 year old? He's pretty smart, and most likely he'll just be turning it on, finding his game and then playing it. I wasn't sure if the GBA emulator would be more confusing than just running it off a slot 2 card. I already know about all the advantages of the DSTWO (movie playback - someday, picture viewer, save states, cheats, whatever....). But I really just want the games to operate normally without too many bugs and very low maintenance on changing emulator settings. Any advice is greatly appreciated. Right now I'm leaning towards just the slot 2 EZFlash 3in1.
