Hi. I am having trouble with these cards. I have both the TTDS (real) and AceKard 2i. I just recently bought a few 4GB Kingston MicroSD made in Taiwan. I can get games to load like normal (fast) in the AK2i but games load slow as hell on the TTDS. I thought it was the DSTT giving problems but I tried in on FOUR other TT cards and the same problem. I have tried reformatting using Windows and the Panasonic SD Format Tool and still no go. It still loads super slow on the TT cards (over 30secs) and load fast on the AK2i. My question is why does it work fast in the AK2i and not the TTDS? Any input would be greatly appreciated. Thank you.
