Have you tried the double swap trick?
I have neo 4 and i can get all the games i have to boot up no problems even some of the EA games that do not direct boot
heres how to double swap
do the swap trick as normal but when you let go of the power reset button and the drive pops out take the regionX cd out and let the drive go back in without putting the copyed game in then when its gone back in wait about 2 secs then press the eject button to eject the drive then insert the copied CD and press eject so the drive closes then press start and it should work
it can take quite a while to get it to work and get the timeing right but after a few times you should beable to do it strieght away
Thanks
Steve
