CivSwitch offers a new offline entrypoint for Switch 2 homebrew

May the good times continue in the Switch 2 homebrew scene! Released today by developer Gezine, CivSwitch offers a new entrypoint for homebrew on the system, this time making use of a physical Switch game in Civilization VII.

CivSwitch Readme said:

XSS toolchain for the Switch 1 edition of Civilization 7.
Only the 1.0.0 version of the game in physical cartridge is supported.

Two components:

• PicoSwitch — clean, compilable Pico firmware (RP2040 + RP2350) that types a chat-XSS payload into the Switch (USB HID macro).
  
  Default payload = the Remote JS Loader bootstrap (exploit core + TCP loader).
  
  Ships with compress.js (chat transport: terser -> deflateRaw -> base-25 chunked img/onerror lines with censor armor).
  
  
• installer-creator — given any JavaScript payload, produces the boot-persistent installer (XSTRIG.Civ7Save trigger written to savedata) to send through the Remote JS Loader

Gezine shows the exploit running in a tweet shared alongside the download.


Those interested should move quickly if previous exploits relying on physical games are anything to go by. At the time of writing the game remains fairly readily available in the UK around the £30 mark.
