Pretty sure I used that boot.dat website creator. (in the pre-atmosphere SX days, it was just the boot.dat file that I needed to have and update when SX made changes)How are you doing the handoff from SXOS Dongle?
There are a couple ways to do the handoff:
Via SX_Gear_v1.1.zip (this replaces boot.dat and directs to a file called payload.bin)
or
https://sx-boot-dat-creator.herokuapp.com/ (this takes any payload such as Hekate.x.x.x.bin or fusee.bin and makes a boot.dat out of it)
I'll make a new boot.dat from the latest Hekate file and plop it in the root. Anything else I should do/change in addition?
