I will be purchasing this, even though I've already sent out for a I Touch 2. Why? To learn more of DSi flashcarts.
Look, AceKard2i is a pretty great flashcart, we know that, but its being endorsed as if literally being the BEST. Its becoming another R4 for gods sake (Believe me; Once I had gotten my friends to get them since they have DSi, they began to make it as if it where god sends, and now EVERYONE wants them. Jesus crap, come on! ANd after I talked about getting an I Touch2, he began saying he will too; annoyence!)! We help endorse OFFICIAL flash carts, we help create better flash carts for everyone to enjoy.
The way that SuperCardOnei's specs are, they are easily better than an AceKard2i in most aspects, but for now we need to remember that until we correctly hack a DSi, all carts we will be getting are just place holders till then. AT the least, we get ROM loading and MP3 playback, but these carts are likely going to be rendered useless in a few months (Except SCDSOi, oddly, since it does have the loader and is teh only current flash cart that can be updated.), so we best live them up for a while.
And seriously, why would SuperCard team wast time on a GUI when the firmware would need to be changed significantly in the future? Expect the firmware update to contain new GUI stuff, since they would need to for DSi based homebrew and GUI based DSi programs anyways; just have patience everyone!
Hopefully that was a sound statement, xD.
