You make them. Like:Where are those "profiles"?
[CFW - emuMMC]
fss0=atmosphere/package3
emummcforce=1
kip1patch=nosigchk
atmosphere=1
icon=bootloader/res/icon_payload.bmp
But you also need a proper emummc.ini, located in /emummc. Already forgot what kind you are using. It's easy if you're using file-based, just follow the readme. For my partition-based (first partition as it was originally created by SX):
[emummc]
enabled=1
sector=0x2
path=emuMMC/RAW1
id=0x0000
nintendo_path=Emutendo
Both of these things existing and proper, nyx should tell you that emummc is enabled. And although undesirable if you intend on using an old firmware (why? seriously?). autonogc=1 is undesirable and causes a black screen in MANY circumstances if you dare boot your console with a game cart in the slot. If your sysnand is like 4.0.1 and you want to keep it there, more power to you. If it's above 4.0.1 there is seriously no point. Change that to a 0.
