its physically impossible to make a 1:1 copy of a xbox 360 game for various reasons without a pressing plant.
Ever seen how retail discs are being made? It's all burnt initially by laser. The difference is that this "burner" can write any type of binary code to a disc. ECC corection codes, TOC etc. can be inserted to a disc not by laser firmware itself but by its software in initial image preparation. Laser can do whatever you "tell him straight to do" only if you do it in low-level code.
eg. bad sectors are not something which your drive can't read, but can't interpret logically due to wrong corrections added by a system software- not by the laser. You can't burn bad sectors to a disc because your firmware is unable to do it. furthermore you cant burn whole sector of zeros cause your firmware will always add extra byte of correction to an every single byte.
other words: we need a firmware which is making full rip of disc - not only data but whole data sectors with all its redundancy - bit by bit. All data-readed corrections should be done by software on ripped image- not by a firmware (non scratched retail discs never have any "Parity Outer Failures" which require extra sector read)
And of course a burning software for a (low-level) firmware which is burning all data just without any other "internal" modifications.
It is possible but not easy to do. Ask c4eva how he fooled drive to burn 8.7GB to 8.5 disc. You could force drive to write DL 10GB to a SL 4.7 disc with a success response and guess what...after all your burner would be still working.
Sorry for bad english.
