Made a backup using boxplorer, I just selected all the files except the ones that won't copy. I have made it to the ?sewers? with ghost, to the airport with niobe, and completed the "hacking" BS. Eerything has worked fine so far; No locking up, perfect sound, ect. Whatever those files are, they must not be very important.
Just so you know, I'm using Avalaunch 0.45 as my main dash, copied a retail NTSC version of ETM, I used XBOX Xplorer (didn't copy the 40 some odd files, I didn't count so I'm not 100% sure), using latest xecutor bios.
Just the same, It would probably be a good idea for someone to find out excatly what is in those files.
