Basicly it uses the same solder points, but for example hw core uses flex cable (you remove emmc from switch and insert it into socket of hwfly (no dat 0, clk, dmd soldering is needed), howewer with pico you have to solder this points to a very little soldering pads
only limitation is launching hos. At first we got encrypted uf2. Then one polite person created a new account and dropped working firmware with no hos supported (no piracy is possible at this moment). But this is all what i needed.
