 Now you can build picosim for the Pico RP2040 with these commands:
 
-	cd z80pack/picosim/rp2040

 This machine can be used with Pico and Pico W boards, it is setup
 for a Pico board. To setup for a Pico W comment/uncomment the lines
 in CMakeLists.txt. It doesn't really matter, on a Pico W the CYW43
 gets intitialized but is not used yet.

 The machine is configured for USB UART so that no additional parts are needed
 to hook up a terminal. The default UART also is enabled, to use connect a
