Not sure if it can be changed but from first post it looks like it's expected
How to properly update emuNAND on an O3DS or 2DS:
Boot into Emunand, and launch System Settings.
Make sure it says RX-E or RX3D in front of the version number to be sure that you are in emuNAND
Do NOT exit System...
I'm stuck on step 14. When I launch RXMODE SysNAND I don't see the big blue menu app when I navigate to H&S.
What I did
The original hs.app was 836kb and it generated two files (no banner 648KB and with banner 400KB)
Renamed with banner to hs.app
launch decrypt91ip > sysnand > inject H&S...
