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

If you only want to forward Dekopon you can just use the NRO Forwarder option.

hey guys just chiming in to say thank you for the emulator it works well. im playing pokemon ultra sun, and well it does freeze frequently for 30 seconds to a minute at a time it unfreezes and contiunues to play only once did it crash to the dekopon menu but that might have been due to cheats overall if your patient the game is playable. hopefully this will be fixed in future updates but overall im having fun with it so thank you and keep up the good work

Are you on the latest pre-release version (v2.2.3)? If so, could you share the azahar.log file from the logs folder from a run that had this freeze?

Sure Does it create a new log file every time I run a game

Every time that you launch the emulator a new log is created. Only the last two are kept in the logs folder.

Reporting it in case nobody has mentioned it already: if the emulator has been suspended for a long period of time, like when the console goes to sleep mode and you leave it like that for hours, once you open it back again the game freezes. At one point, after a long while, it resumes execution of the emulated game as usual.
While the whole thing is happening, Status Monitor Overlay shows the core 2 being used at 100%, core 0 and 1 at 0% usage, while the core 3 reserved for the system does its own thing, nothing ever crashing.
The emu's menu, screen swapping, that stuff seems to work though quite unstably and slowly sometimes. It's all very strange.
Has it happened to anyone else?
