(inb4newfagcomment) I'm having some issues playing Pokemon Black (U) using TTMenu. How do I know this for a fact? Well, I've been playing the (J) version lately and that has gave no issues whatsoever, besides the fact it lags tremendously. If I am playing the game, I am satisfied. I've tried doing several things such as, 1) Going to R4i-SDHC.com and installing a upgraded firmware for the R4i SDHC 2) Formating my SD card using the program provided for the maker of the SD card. 3) Paper trick. (Use GBA-Temp and you'll see why.) 4) Waiting 10 - 25 seconds on TTMenu. Thanks!
