To those who got this file to work, what version of berryboot were you using? I keep getting an a critical error with the kernel and it boots into an emergency kernel. Anyone that could possibly shed some light? I've been trying everything to dual boot PiMAME
Quick followup, I retried the install with NOOBS and followed advice in another thread by installing raspbian and openELEC. The mistake I made the first time was by modifying raspbian to automatically boot into the gui. You have to keep the default which boots into the command line.
