Hacking Proof that almost all R4i-SDHC/R4iSDHC carts are literally the same carts.

Nice investigation. I bought a 7,99$ R4-SDHC (non-i) last month, I needed it for a DS Lite and I figured out it was enough for me since I didn't need the functions of the RTS chip anyway. After reading this, turns out It was a fine choice. RetroGameFan's YSMenu works great for me.

Just wondering: should I get my hands on a 3DS in the future, could I backup my card's kernel, flash it with the R4i-B9S kernel file (as it can be done on the Gold Pro and RTS Lite) to use its CFW-enabling function, then flash my own kernel backup back? Or, is its chipset too old for that?

The b9s flash backup only works with the latest 3ds compatible cards from r4i-sdhc.com etc
