I think I have an old exov mod in my system. Can the software or Bios be upgraded, and if so will this make a magor difference to the performance? I have been having problems getting my back up games to run ( ie: reconize burtnt dvds/xbox games )
Yes it can be updated and yes it can make a difference. Just like with any program, updates produce fixes for problems that may have existed in the previous version. First, try deleting the CACHE files from your xbox and see if it fixes your problem. E:/CACHE/"delete the files here"
