Hacking Hexflow not finding PSP and PSX games

[Olat]

Hi guys!

I am experiencing an issue with Hexflow for the PS Vita and I was hoping someone might have a solution.
Namely - the launcher does not find any PSP or PSX covers.
A similar topic has been opened here, but I fail to understand the solution offered: https://gbatemp.net/threads/hexflow-launcher-not-finding-psp-ps1-games.589488/

Any help would be much appreciated.
