I read the artice about booting with the eject button to play DOA4, so I've been doing that. Just recently I went to play DOA4 w/ my friend. When I signed on, it said Player 1 pick a device to save...so I turned off the xbox 360 so it didnt save over my other game. I went to settings and memory and under my profie, DOA4 was STILL there...amazingly . Now whenever I load up DOA4 it says Player 1 pick a device to save. If I hit cancel, it wont save or load. If I pick the hard drive (I havent done this yet) im afraid it will overwrite my old save game that is still on the HDD.
