Was looking into getting a flash cart for my ds for a number of reasons and was just wondering what people thought was the best one?
M3 flash cart and others visit here http://yallstore.com/nintendo-ds-ds-lite-memory-card-c-762_903_952.html
I agree with the M3 Real - the R4 original is no longer supported as is the M3 Simply, so avioid those. try dealexreme.com, cheaper than the above link and free shipping
Have an R4 and its good, the Supercard is great in that it supports HIGH capacity cards. R4 is hit and miss with some supporting 2GB and some 4GB. I loaded up a Supercard DSONE with an 8GB card this morning. nxpgames.com has good stuff on it, and its US based, so ordering from them will make everyones stock go up. : )
There's CycloDS, which you can say is one of the best out there, but it's a bit more expensive. However it works great and has many more features then almost any other Flash Cart's. Personally, I'd say the M3 DS Real is the way to go. What you need to know is, it comes in 3 different pack. One is the basic M3 rumble pack, the other is the M3 rumble/ram pack, and the last is rumble & GBA expansion Pack. It's affordable and reliable. The main reason why I choose M3 is because not only is their product good, but the M3 team is great as well. They are the only team (that I know so far) who's currently working on a few programs and apps for the M3 DS cart. This include map (the same ones that the PSP used) and such. But every cart differs from one another. At the end of the day, it's really based on your preference.
