as owner of the acekard2 i can say its a great card, but the 100% compatibility thing is a lie (maybe it should be fixed in the review, see the posts in the acekard forum about lots of ppl having troubles with different games) aswell is the "no slowdown" promise.
castlevania lags horribly on my class4 sandisk 8gb.
i know this can be fixed with a class6 card, nonetheless its a lie to claim "no slowdown on any card".
no matter what, its a really great card, great menu system, perfect touch controls, great skins.
thats why i prefer it over my cyclo ds, which is no doubt the better card otherwise.
@urza: nice review, but its not accurate. there is NO 100% compatibility, soft reset does NOT work 100%. there are games where it doesnt work at all (for me its new super mario bros EU) or games where there are bugs after a soft reset within the menu system, like only icons and no filenames displayed, top screen not showing anything at all and stuff. see acekard forum for other people reporting. thanks.
