DSO nano v3 to gamma grapher

Hi all,

I buy dso nano v3.29 like follow

youtube /watch?v=MbCXO0FNKwc

and I update the firmware to 4.21
and I’d like to make DSO nano 201 to gamma grapher - spectrometer like follow

But it can’t do that because the GGN_0_24 can not run on my DSO nano 201.

What can I do to dso nano run as gamma grapher?
