Hacking Nooby Questions 2.0

[fjr69]

Hi Guys,

First of id like to thank you all for being such a great help for all the Questions one might have,

I'll get right to it: I have 9.2 Installed on sysNAND and 10.7 on emuNAND

Is there a way I can set the System to boot sysNAND by default, and emuNAND by holding the R key on boot for Example?

I have my OTP and the Arm9 Files on the SD but I don't want to mess with sysNAND i would like to keep that Untouched..
