At the moment it only supports flashing Jasper 512MB big block nand through the sidecar, configuration can be adjusted in SFCx.cpp, support for USB flashers (NAND-X, etc) is a future goal.
A lot of the code is still a work in progress, so it may be messy and pretty confusing but I've been trying to clean it up as I go.
I don't take any responsibility for bricked consoles.
Use this at your own risk.
