Hacking Sakura not working for 3DS

[Saf1]

I recently changed the F_Core to the latest one for 1.4.2 compatibility (Spongebob) and I replaced the System folder with this one (the 2/18/11 link at the very top), yet when I try to boot game from it it doesn't work.

The weird thing is with the non-sakura version it would work and boot up games. Is there a working Sakura file for the 3DS?

Never mind. Got it to work by downgrading to 4.8x, but it was a pain to find it.
