Personally i like the DSTTi it takes my 16gb micro sd card no problems, but now the dsi games are coming out everything above avatar it not loading falling on error-4 code, plus they are slow updating firmware not that i can do better, just want a more up to date card that you can have more success using arm7 to patch games more regularly updated firmware and higher compatibility with games. also i use moonshell 1.71 which is out for most carts but don't want one that has known faults. I'g guessing Acekard 2i and M3i zero? what card is doing the best at the moment? I need 16gb compatibility. some games like sonic and sega all stars racing runs on some carts no patching.
IMHO, it really depends on which development team has the best reputation.
If money and time were no object, i would be on the CycloDS team, but their non-release of a DSi Flashcart to this point indicates (to me) 1)They are being extremely cautious in their development to future proof their product, or 2)Heaven forbid that they see this as a "no-win" game and will not product a product.
I am betting on Acekard2i and EZFlash Vi teams to be the winners, based on longevity.
@MaryD7. What's your opinion on the offering from the Supercard camp?
