Emulating .uf2 files?

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. 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.
