@mitu Thank you and @dankcushions. I updated to 4.8.2 and now see the script. I have installed it. I appreciate your help!

@isidoro80 I did these tests:

I have the game rom F-Zero X - Expansion Kit (Japan).ndd (CRC32: AE31F57F)
in the n64dd folder I put 2 files for the game: F-Zero X - Expansion Kit (Japan).ndd and a pair of the file ipl.n64 (japan CRC32: 7F933CE2) file renamed F-Zero X - Expansion Kit (Japan).ndd.n64 and not work.

where is the mistake?

@BuZz : I saw this menu, but it provides me only with the choices "bookmark" and "share".

raspberry 3b+ , retroarch 1.8.4 , retropie 4.5.1. Touch wait for the solution.
