vWii without one of the exploit games is by using applications called wuphax or Compat Installer. Wuphax uses the public Wii U IOSU exploit to temporarily inject the HackMii installer into the Mii Channel so that The Homebrew Channel can be installed without an exploit game. Compat Installer uses the public IOSU exploit to install the Open-Source Homebrew Channel from Wii U Mode. Nintendo Switch The Nintendo Switch was first exploited by a team called ReSwitched. On March 14, 2017, about 11 days after the console's release, the team released their exploit to the public. This exploit was called PegaSwitch. It did not allow true homebrew to run on the system at the time, but it did let developers look for other security bugs in the system. Later that year on October 1, ReSwitched announced new exploits and tools that allowed homebrew developers to start working on homebrew programs for the system before they could be launched. At the 34th Chaos Communication Congress, hackers Plutoo, Derrek, and Naehrwert announced a kernel exploit for the system (which they said would not be released) and said that a homebrew launcher was coming soon. On January 7, 2018, Twitter user fail0verflow uploaded a video showing a simple side-scrolling text program before booting the system, which shows that there was a way to run unsigned code before boot-up, opening up possibilities for new programs focused on development. On March 29, 2018, SciresM, a respected developer in the homebrew community, announced that a custom firmware called "Atmosphere" would be released for all available firmware versions at the time. Firmware above and including 1.0.0 are hackable via a cold boot exploit known as Fusée Gelée, developed by the ReSwitched team. This exploit takes advantage of a bug in the boot ROM on the Tegra X1 chip used by the Nintendo Switch. The exploit was also independently discovered by fail0verflow under the name ShofEL2. Firmware version 1.0.0 is hackable via a TrustZone exploit known as Jamais Vu. Atmosphere released its first public build in October 2018. Currently, the Nintendo Switch has both a homebrew launcher and custom firmware. Access to a Japanese copy of Puyo Puyo Tetris is needed to install CFW on version 1.0.0. The ability to install homebrew on the Nintendo Switch is also dependent on the version of the console. As consoles that were released after June 2018 with version 4.1.0 shipped have their
