Question: I have the x86 version burned to a USB. Boots fine, plays games fine. How do I add ROMs to the USB itself?

When selecting the storage option in settings, it giving me a whole bunch of selections..."SYSTEM" (which i believe is my computer), "RECALBOX", "BOOT" and "NO_NAME".

I wanted to try to load it by network, but it does not connect after inputing all the information.

I remember trying the no name one, but it completely detroyed the installation and had to repartition, reformat and reinstall.

Any suggestions? Or is this not possible?
