No need to press anything: https://gbatemp.net/threads/can-someone-do-this.584945/#post-9424212do you still need to press the button to apply patches with plugin loader. that was my biggest problem, because you had to do two button presses at every boot if using cbhc.
Howto:
- Exchange wiiu/apps/homebrew_launcher/homebew_launche.elf on your SD card with the wiiupluginautoloader.elf file from the link above (make a backup before).
- Put the WUPS_dark_mode_plugin.mod file to wiiu/plugins on your SD card.
- OPTIONAL: Create wiiu/plugins/autoload.txt with the content "WUPS_dark_mode_plugin". See the link above for more details
- Put the SD card back into the Wii U. Boot it and while it shows "Autobooting..." press the home button.
- Change "Autoboot: System Menu" to "Autoboot: Homebrew Launcher".
