I am building a new cheap PC to put a new installation of Lakka on. What would be the easiest/quickest way to transfer ROMs between the hard drive on my old laptop version of Lakka to the new PC?
You can try to plug both disks and if you know some shell command to copy it from one disk to the other one.
Otherwise please read this documentation about how to access Lakka filesystem..
Thank you.
or you could try to connect both computers with a crossover ethernet cable and share the folder then copy/paste
What I did was with both on the same network, I would connect to both using two file browser windows on a third computer and transfering from one to the other. Or keep all the roms on a secondary drive and just unplug the drive from one and transfer to the other.
