R36S No PSP Emulator

Hello, I received my R36S today. I was really looking forward to it, but unfortunately I noticed that there is no PSP installed like on other systems and many games are missing on the PSX and N64. Support from Aliexpress is a disaster anyway. Since I'm getting a new SD card and, as described in many videos, I want to install a new Arkos, will this install a PSP emulator? What can I do? Sending it back is pointless. I got it for 20 euros.
