I'm using Retro's updates. Menu isn't lag, but when I try to load up a game, sometimes it loads fast, sometimes it loads for 30~ seconds. Pokemon Black/White gives me a lot of lag when walking and on battles. Pokemon Platinum/HGSS gives me lag on the Backpack/Pokedex. I tried Wood for DSTT, and it doesn't lag at all. It loads the games fast, plays Pokemon games without any lags. I'm using a TDK 4GB SDHC. Using a 1GB Memory Card has no lags even on Retro. I don't think it's an issue with my SDHC as I can use it without any lags on Wood. Thanks!
