Hacking RetroArch on PS Vita: How to create a database and sort all roms by system?

[Bravestarr]

I have a problem with RetroArch 1.7.7 and 1.7.3 on my PS VITA 3.60 on enso. I put all roms in UX0:data/rom/gba, UX0:data/rom/snes and so on. Then I try to scan the folder (see screenshot) but nothing happened. I tried to scan each subfolder (snes, gba) on its own. I know that once I had a version of retroarch on my vita that could after scanning list each system with the name of the rom. Now I have to select each rom by "load content" and select the file. What am I doing wrong or what do I miss?

There is no "database" I can download or create. How can I get the lists with thumbnails in RetroArch on PS VIta? Or is this feature gone for good?

What helped me: Just use the version from the vita homebrew installer and everything worked as intended.

you can also get the latest version from https://buildbot.libretro.com/nightly/playstation/vita/

make sure to also download the *_data.7z - this contains the rdb databases for all supported systems (needed to scan rom dirs)
