ZIP with binary files.....
The point was to make it easier, without any need for additional ST
programmer, like this:
„Instead of needing drivers or a separate program for flashing (say, bossac,
jlink or avrdude), one can simply drag a file onto a removable drive. The format
of the file is a little special. Due to 'operating system woes' you cannot just drag
a binary or hex file (trust us, we tried it, it isn't cross-platform compatible). Instead,
the format of the file has extra information to help the bootloader know where the
data goes. The format is called UF2 (USB Flashing Format). Microsoft MakeCode
generates UF2s for flashing and CircuitPython releases are also available as UF2.”

I didn't use such kind of files yet — but if the Mecrisp guys were
able to prepare it for RP2040, then it must be feasible somehow.
I'll try to „convert” your binaries.
