First, I'm not including the ability to play 3DS backups on this list because we know it'll probably be an year or so before the 3DS flash carts gain the ability to do that. Besides, until there's dozens upon dozens of 3DS games that I end up with and don't want to carry with me everywhere like I did with the DS and the GBA, I don't really care about 3DS backups anyways.
So sans the 3DS mode, here are my dream features...
1. The ability to play Gameboy Advance backups without any problems, tested to work on US launch and European Launch 3DSs as well
2. Obviously, the ability to play your DS, SNES and Sega Genesis backups, off of MicroSDHC cards
3. A nice looking easy to browse menu like the CycloDS
Optional: The developer or the card itself offers a way to block wifi from connecting to Nintendo's servers, so that you ever have to worry about some doing an update and thus bricking your system, preferably while still being able to play multiplayer.
Optional: The card has a way to hide itself so that there is no record of your 3DS having used a flash cart.
Optional: The DS backups can be played stretched to fit the entire top screen rather than showing a horizontal black bar on each side as is done now. The GBA, SNES and Genesis emulators also playing in widescreen mode goes without saying.
What do you think of my dream feature list? What would you add?
To my knowledge, the ONLY card that meets all the first three requirements (including the ability to play GBA games on the 3DS) is the SuperCard DSTWO am I right? Or am I wrong in that?
