Hey man. I have been keeping an eye on this project past few days.
It was a nightmare trying to get things to work. It would work only in japanese, or it would only work on Desmume etc etc.
What ddc1 said is completely right for people having trouble with DSTT for either R4 or R4i. I couldnt get it to work for my R4i at all but eventually after downloading what he put up, it all worked.
What I did was I first patched the file then downloaded the file ddc1 uploaded, ran the eNDryptS Advanced (Essential to run as admin) and put it onto my DS.
Personally, I made about 4 files per try and did a little tweak on each.
I transferred one over with the old patch, the new patch, no patch and old patch overwrited by new one. The new patch by itself is that one which works, for what its worth.
Thanks again lads.
