I have a Sandisk 8gb class 2 card. I also have a 4gb non classed SDHC card. Both seem to make no difference in speed for file transferring or in emulators like GnGeo or FBA2X. I was wondering if there are hardware limitations with the transfer speed of SDHC on the Wiz. Will getting a higher class card make any difference what so ever? I know large NeoGeo games that are cached in FBA2X run really slow, even with overclocking. That is probably cause of the emulation in FBA2X, but does anyone notice a difference in speed with higher class SDHC cards? Also is there a limit to the class of the SDHC that the Wiz will recognize? If I got a new class 10 card will it even make a difference? Thanks to anyone with any input.
