My jtag plays 360 and XBLA games from the hard drive (dvd rom is fooked) but will not play Xbox classic games, just freezes on the white screen with the green X. I'm pretty sure I have all the correct files in the correct places but is there a guide for this somewhere?
I've had nand issues recently but am now flashed with a Freeboot 13146 image, with my correct console serial number and drive brand, but the wrong manufacture date (donor files). Does the nand effect classic Xbox games or should they work as everything else is working.

Any help greatly appreciated.
