Just download the multicart update on page 1, or rather go to filetrip and get the 6.51 multicart update, then inside theres a folder called r4sdhc r4i-sdhc ttmenu, inside is a ttmenu.nds and a ttmenu folder, just copy those to the root folder of your memory card, then bootup click the icon on the left of your regular r4 firmware, then run ttmenu.nds which will be in the list.
Or if that gives you the same loading problem Im having, Try using the folder in the multicart update called r4clones, inside is ysmenu.nds and a ttmenu folder, copy those over and run ysmenu.nds in the same way as above.
Biggest thing to know with the r4sdhc cards is you have to be on a base firmware lower then 1.31, after that they started adding that pandora.nds file and it conflicts with RFGs ttmenu, hence the reason Im on 1.26 base firmware, well that and dslibris gets constant errors on anything higher and I read a lot of ebooks on my ds.
