That is exactly what I'm looking for, do you have a
tutorial reference for that configuration ?
I can't recall how I set up the Vol- but I think it is based on the trinket UF2 payload.bin/upload.bin using hekate and fusee primary payload bin files respectively.
Anyhow, I never bother with Vol- or anything these days and just always boot to hekate and pick whatever option from there by renaming the hekate bin to payload.bin and put it on root of SD.
See
https://gbatemp.net/threads/trinket...software-new-fusee_suite-uf2-packages.553998/
FUSEE_UF2 for Trinket for more details.
The trinket automatically boots whatever it finds as sdroot:/payload.bin (renamed latest hekate.bin to payload.bin) if no other button than power on is pressed and that's good enough for me to access the hekate main menu.
So first thing on a fresh card is to create the relevant partitions with hekate for Atmos emummc, Linux, Android and then setup the emunand for Atmos.
Once done copy all your atmosphere files, sx os boot.dat and configure the hekate_ipl.ini and bootload .ini files for whatever to load like Stock, Atmos, SX, L4T, Android. Lakka
Here's my hekate_ipl.ini - simple bare bones.
[config]
autoboot=0
autoboot_list=0
bootwait=3
backlight=100
autohosoff=0
autonogc=1
updater2p=1
bootprotect=0
[Stock]
fss0=atmosphere/fusee-secondary.bin
stock=1
emummc_force_disable=1
[SX OS]
payload=bootloader/payloads/sxos.bin
[Atmosphere]
payload=fusee-primary.bin
I have the inis for booting Lakka, Android and L4T in bootloader/ini and you can have these show on main screen along with the above configs by going to hekate Nyx Options/Home Screen and choosing All Options. I like this, just one place for everything.
Test it all out, then boot into SX OS and setup file based emunand for SX - it's fine and speedy enough.
Finally, although you can share emunands between SX and Atmos, due to SX seemingly now being defunct, I think it's important nowadays to have separate emunands for Atmos and SX so that you can keep either one updated independently, ie have Atmos emummc at 12.0.1 and SX at 11.0.0 at time of writing.
