Steam Deck EasyRPG Core

I’m currently trying to figure out how I’m meant to get the EasyRPG Player core in Retroarch to recognize the RTP files on the Steam Deck. Every tutorial I’m finding says to put it in a folder path like “data/rtp/2003”, but what/where is data supposed to be? Has anyone else gotten EasyRPG working on the steam deck without any errors?

the RTP must be placed in the RetroArch asset directory where also the content downloader puts the stuff.

This is finally documented since a few weeks here: RPG Maker 2000/2003 (EasyRPG) - Libretro Docs
