-- I have done this with many emu's and apps already and had no issues . I have done daedalus , quake 2 , xsnes , xmameb5 using Nero 5.5.9.0 - DAO - close disc onto TDK cd-rw @ 4x write and they all work fine [ Quake 2 takes a little bit to load ] . I did Xmame @ 10x write the first time and it would not run 100% . Be sure you are using media that work in your Xbox and be sure that you are burning them slow enough [ keep trying down to 1x write if it needs it ] . I used Xiso to compile the iso image , I know this is not supposed to be needed as you can just drag & drop but it works just fine for me .
