My recalbox do not include psp ps1 emulators.

My hardware is rock64 1g ram,with beta v2 installed. I can't find psp ps1 parts.
And another question. How can i read the roms in external usb devices?

By the way, I've tried lakka before, but lakka can not support my xbox one controllers. Instead, recalbox is perfect supporting controllers.

@joyburrito please, refer to the pine64 forum for any question regarding the rock64 at this moment, as it is still an unofficial port.

For your second question, take a look at the wiki:
