I am currently set up with EmuMMC and atmosphere.
I know it's possible to create an emunand in SXOS and have it work as EmuMMC.
Is the opposite possible?
I would like to have SXOS as an option for booting XCIs from an external drive.
If anyone can shed some light on the possibility of Using EmuMMC with sxos without having to start from scratch with my emunand.
Much thanks!
