I’m working on an operating system in **PXT TypeScript** as a fun side project. However, the **XTRON Pro** I was testing it on unfortunately broke. Additionally, it didn’t seem to have the networking capabilities that were promised. After checking the pins, I discovered that the XTRON Pro failed to communicate or even use the pins at all.

I’ve since purchased a **Meowbit** with the **Wireless SD card** , which can connect to WiFi using my modification of the **NINAController** : [NINAController Code](https://github.com/Renderthegreat/renderlabs-soup-os/blob/master/distro/net/nina.ts). While I’m waiting for my Meowbit to arrive, I realized it might be faster to emulate the OS locally on my laptop.

Is it possible to emulate a **.uf2** file on my laptop, specifically for the Meowbit? Ideally, I’d like to simulate the environment and test my OS before the hardware arrives.
