Hacking DSt graphical glitch?

[T3GZdev]

(wasn't sure if i should post this here or not but...)
with that being said, hi im not sure if its just me (or the current fw version of DStwo) or the way the card runs. but iv kinda noticed a graphical glitch when running homebrew on DSTWO(on DSi & 3DS).
the lighting seems to be kinda off when running a DSTWO card on 3DS or DSi.
it seems to work on DS EMUs, DS/DSL(DSTT, Acekard2i, DSTWO), & DSi sudokuhax.
ill let the pics explain.

desmume & no$gba how it looks.
