Well, i had a review sample, the only thing i can say, it works nice, i don't have any problems connecting it to pc, drag and drop is just perfect and fast, saves fine, (didn't try mario and luigi game yet, will do that this evening when i get home).
I bet the ds-x tream is aware of / reading comments and will fix it.
i think so far ds-x is one of the better kits for nds, i'm sure once acecard gets released it will also have some trouble, same for any other card that gets a first release.
The only drawback is the 512MB, but on the other hands, i only play 2 or 3 games at once, not 20 or 50
64Mb game x 56 = around 476MB
128Mb game x 29 = around 478MB
256Mb game x 14 = around 469MB
512Mb game x 7 = around 469MB
1Gb game x 3 = around 402MB
(You need to leave some space for the os needed files and saves.)
For me that's more then enough, got a mix of all, i have around 8 games stored on it, that's more then enough
no patcher needed, also makes alot of things good, no waste of time on that.
