JoyHax v1.0

Today I'm bringing you my personal project that I started on NS launch day!

JoyHax is a complete NS CFW installation tool that sets up a REAL coldboot CFW solution for your
Nintendo Switch, on ALL VERSIONS!

Simply run JoyHax.exe and follow the on-screen instructions to install JoyHax on your NS!
​

Features:

• NRO Installer Included
• Works with fw 1.0.0 - 2.3.0
• Full firm0/firm1 modifications
• Launches NRO files with invalid signatures
• (Almost) Brick Proof
• Cartridge Dumping
• Save Dumping/Restoring

I am NOT responsible if you brick your Switch while setting up/using JoyHax!
While there are PLENTY of safety checks and hash verifications during the JoyHax
installation process, I cannot guarantee anything bad won't happen!

Current Bugs:​
