I have a modded Nintendo Switch Lite running emuMMC. I updated my SD card using the latest HATS Pack released on June 17 and then updated my emuMMC firmware to 22.5.0.

Since the update, Atmosphère will no longer boot and immediately gives me the following error:

A fatal error occurred when running Atmosphère.
Program ID: 010000000000BD00
Error Desc: std::abort() called (0xffe)

Report saved to:
/atmosphere/fatal_errors/report_000000000b955b30.bin

My current setup is:
  • Nintendo Switch Lite
  • emuMMC
  • Firmware 22.5.0
  • HATS build: HATS-2026-06-17-c4f822a
  • Atmosphère 1.11.2
  • Hekatos 6.5.3

Everything was working before updating the HATS files and emuMMC firmware.

From what I have found, Program ID 010000000000BD00 may belong to MissionControl. Since MissionControl was included in previous HATS versions but appears to have been removed from the June 17 build, I am wondering whether an older MissionControl sysmodule was left behind when I copied the new HATS files over my existing SD card.

Would the correct solution be to remove or temporarily rename:

/atmosphere/contents/010000000000bd00

Should I also remove the related MissionControl Bluetooth patch folders, or is removing the contents folder enough to test whether it will boot?

I have attached a photo of the error and can provide the .bin fatal-error report if needed. I would prefer not to rebuild or modify the emuMMC until I confirm this is only a leftover sysmodule issue.

Thanks for any guidance.
