Hi this information is most interesting and at first thought that you were describing one of the other guys soundboards. Have never heard of an US board being able to do all these functions... and my 2.1 certainly can not.
Are you really sure? The US 2.1 is only a US 2.0 with updated software (to fix 'flicker settings mess with brightness' & 'power break required for booting' issues).
When the saber is turned off, press the button and hold it -> The blade should not turn on during that and after several seconds you are greeted by a voice saying 'main menu'.
The 'bouncing switch issue' might be the main reason if menu is really difficult to access...
Is there a video out there where Emory is reviewing the features ? Am wondering if perhaps Windows 5 was being used or if this board was not computer compatible.
Alas not. All YouTube-links I found have been taken down ages ago (afaik it was Ultra himself in those old videos). This 3rd-party video is still alive:

point for finding this
Thank you
Note3: Recommendation for the capacitor in the switch circuit is 50V, 1uF.
