Lakka live mode in USB

Hi All Bro,

I found there have a unknown issue and make me confuse.

I have some experience before create Lakka in PC , orange PC & Raspberry which is success and smooth run.

Then I try use live mode then add roms/cores/bios etc, but I found that all FBA & mame game all not working shown fail to load libertro, I have try make change in cfg file the location of cores but still not working.

After that, I create the usb Lakka by installer but still the same problem as above.

finally, i try get the harddisk from computer which and make it in USB case, but all game run is smooth.

Any idea for this case?? I very confuse and no idea…
