Through a new YouTube upload by Switch hacker Rei/Reisyukaku, we've been given a tease for an upcoming new custom firmware for the Switch. Nothing was officially stated by the dev as to what features or differences it'll have compared to other options, but from what the almost 40-second long video shows, we can see an edited boot screen, and that it can definitely boot into the hbmenu, with some homebrew listed. The dev's official site lists ReiNX as a custom firmware for the Switch, and says a Github page is coming soon.
