dstt help

im having some issues with my dstt, everything was working fine and all with the 1gb sandisk micro sd card but then I got the 8GB sdhc card from newegg and lag in the dstt menu. I have no problem scrolling through the first 4 visible games but when scrolling down or up it takes about 5 seconds till it actually scrolls down or up. also whenever the cheats are always in Jap lol everything else is in English except for the cheats lol. i didnt download the kernal from the official DSTT site because I think the site is down, not working for me anyways
