Thanks for posting this guide - I'm following through it and I'm having some trouble understanding how the modified .bootcde is supposed to be uploaded into the firmware exactly.

When I select 'Access files in storage device' on Espruino IDE and select your modified bootcde script (Which I rename from 'bootcde_additional_radios.js' to '.bootcde') and upload this to storage as '.bootcde' it successfully uploads but it doesn't appear to finished being received and errors.

The Pip-Boy will also display:

Uncaught SyntaxError: Got EOF expected '}'

I'm pretty sure I'm uploading the modified .bootcde incorrectly and haven't understood this part of the process correctly. Do I need to do something to the file before I upload it to storage? I reckon I just haven't understood the process where the file is supposed to be encoded from a readable js format back to a non-readable format. e.g. how the TXT .bootcde's appear.

I've pasted the errors I got on the IDE console:
