The developer thomleg50 has just released a new Homebrew application for the Nintendo Switch, Fusee-starter will allow you to launch a Payload after a reboot.
Good news, this Payload is compatible from Atmosphere 0.8.3 or higher or Kosmos, and it already has support for Rocket, ArgonNX and hekate.
fusée-STARTER is a modified version of reboot-To-Payload from Atmosphère-NX.
All payloads are included in the NRO, which means that no other files are required to run them.
– Correction on the code
– Updated hekate in 4.9
