Softmodded my xbox, about half the games I try don't boot.

I softmodded my xbox using xboxhdm and Shademand's ready made softmod. So far I've tried playing Halo 2, Ninja Gaiden Black, Riddick, and Prince of Persia Warrior Within. All these games backed up ok onto my hard drive using dvd2xbox, but when I try to play Prince of Persia and Riddick, I just get a black screen which stays. I've tried loading these games from the disc by booting the xbox with them in the try, and the xbox also just stays at a black screen. Does anyone know what might be wrong? Thanks in advance for your help.

 

uhh do you have a disc in the tray maybe take it out if there is one

 

Nope, there's no disc in the tray when I try booting them from the hard drive.

 

oh well i dont know then ....sorry

 

maybe you went over the amount of memory for the e drive with those games

 

i guess it could be possible but how thogh cause wouldnt it not let you copy the game then or maybe it took parts of some games....
what size HDD and what games do you have
