I just recently got the DSTWO and i've had it for about a week and I have been disappointed thus far. Before I talk about my issues; I reformatted my Kingston 16gn micro-sd with the panasonic sd reformatter. I have also updated the firmware to 1.05 and EOS to 1.02 which is the latest versions for this DS Cart. I got the card to replace my R4DS and I expected to not have problems, right? Wrong! I have had non-stop problems with this cart. Now I have really tried hard to be patient with this cart and I understand that it may have issues due to its early life although the thing is almost unusable. -I am limited to about less than a hour of batterly life vs the 4-5 hours I got out of my R4DS. This is even when not using the GBA emulator. -The GBA emulator is super SLOW even when using the extra compatibility .txt file from filetrip. The file got some games to work now but most aren't playable. -Even though I updated my cart firmware to 1.05, I still frequently get the NO SD card error frequently using it on auto-mode. -The freezes are just terrible too... It seems like if the game lasts 5 minutes without freezing, then it won't freeze at all during the length of time I play. The bad thing is that it freezes about 9 out of the 10 times I play. The weird thing too is that even when the game freezes, the music will keep playing fine. It does this on multiple games that I have tried and the in-game DSTWO menu will not come up during the freezes although if I restart the DS, everything will work like normal again. -The usb micro-sd card reader that came with the DSTWO died in the first day while copying stuff to my micro-sd card but I have another card reader that came with the R4...which still works . -My DSTWO did not come with a wrist strap. This is a minor gripe but it would have been nice to have one. Do you guys have any solutions? I really don't want to have to send this card back to ShopTemp. Thanks.
