Modify program from previously burned core 2

[GEttro]

Hi.
I got a core 2 with a previously installed program but I would like to modify it slightly. How can I retrieve the code?

Thank you for your help
My best wishes

You can’t directly but if you use thonny, you can retrieve the Micropython code from the controller as its save on the controller as pure text
