For some reason the card I've been using with my Acekard 2i/Blue Gateway flat out does not want to work in DSTwo. I tried running Castlevania Dawn of Sorrow's intro video because random games were glitching out to find it skips and runs like complete garbage through the DSTwo. Take the same card, place it in my Gateway and it runs fine. Tried a reformat, etc but it just doesn't want to use the card. Is there a current list of cards that are verified to work with this? I came across some but they were so old that the cards are no longer on the market. The SD card in question is a Sandisk Ultra class 10 16GB card Edit: also I wrote the latest update 20150705 to the device as well. Still no go. Also tested a 64GB variant of this card and a 2GB regular Sandisk class 4. I wonder if this thing just really hates Sandisk.
