Despite being “portable ready,” some users report issues:
Problem: “After installing, the game asks for a software update again.”
Solution: You have a base game mismatch. The 10882291 update requires base version 1.0.0 (not a repack or trimmed XCI). Re-dump your cartridge using nxdumptool.
Problem: “Audio crackles during cutscenes in portable mode.” Solution: Go to System Settings → Audio → Change from “Surround” to “Stereo.” The update’s audio resampler has a conflict with virtual surround on low-power mode.
Problem: “The portable mod won’t load in Ryujinx.”
Solution: Rename the mod folder to match Ryujinx’s new scheme: Mods/Contra Operation Galuga/Mods/Portable10882291/romfs/. The emulator is case-sensitive. contra operation galuga nspupdate 10882291 portable
