Homebrew Question Using Expansion Pak in Retroarch

[Starkgod]

is there a guide anywhere to get this working? In Google, there is some stuff about enabling certain things in the cfg file. But I can see those settings in the native core menu, and they seem to be configured correctly.

Specifically, I am attempting to use this function on a gotta catch em all game that has an option to import data via the expansion pak. It never seems to work.

Any ideas? Is there a particular place I'd have to put the pak (sav) data?

Edit for clarity: I'm specifically referring to mupen46plus. The n64 emu. And the transfer/expansion pak. No idea why I didn't mention this.

Update: I found some plugins that seem to be meant for the pc version of mupen64. Im assuming they wouldn't work with retroarch switch? Does no one know how to get transfer pak working?

Ive researched a ton and have found no solutions. Only things relating to other ports of mupen, but not exactly the switch version. I guess this is impossible at the moment.

I found this but it's pretty convuluded: https://www.reddit.com/r/RetroArch/comments/m3xjuc/mupen64plusnext_transfer_pak/ I'm sorry nobody replied, people tend to be pretty useless on this forum in general.
