You can find the mouse resistors on the schematic fairly easily. Stuff from Phill you'll need to charm from Phill!
You'll also need the ROM images, of which one is updated by Phill, and it's not worth using the original (the BOOT ROM). I didn't want to put stuff like that onto the GitHub. Though could be stored on here quite happily I reckon.
Do we know your build buddy?

Greetings, I am posting to report the progress I am making in the assembly of dragon beta, first of all to thank robcfg due to the madness of being able to assemble this project and in a collaborative way helping us to be able to carry out a final assembly of this project.

Brilliant! I look forward to seeing it working. Unless Richard, Mike and Tony get a move on, yours will be the third repro board to be working!

I have doubts about some resistors that I don't know what the value is; They were the following ones:
R25,R31,R28,R24,R21,R29,R30,R22,R23,R26,R27 and R20 since in KICAD there are not the values of certain resistors.
Thanks.

You can examine each in turn with 'E', or go to the bulk symbol editor (small spreadsheet icon) and see each are 15Ω,
