I was able to create a working forwarder using this NSP Forwarder:

https://nsp-forwarder.n8.io/retroarch

Here’s what I did:

Add your box art image
Fill out the title (version and publisher are not necessary)
Core path: the location of the Dekopon.nro file on your Switch SD card, e.g. /switch/Dekopon.nro
ROM path: the location of the given ROM on your Switch SD card, e.g. /switch/dekopon/roms/game.nds
Prod keys: your prod.keys backed up with Lockpick_RCM
Create the NSP and install it with whichever tool you prefer (Goldleaf, Tinfoil, DBI, etc.)

That worked for me.

so i did what you said and it worked however it launches straight into a game but i can exit to library and from there pick what game i want so i guess its cool how come in the file path for roms you had game.nds could that be what im missing because i just did /switch/dekopon/roms for the roms path and for the core /switch/dekopon/dekopon.nro
