Pease help me!...........

[Excalibur007]

So far, I'm having problems with every game I've tried.
I tried "Extreme Sports" and it will start the game intro, but when it goes to the loading screen before the main menu, it resets and reboots. MSR does the same thing. It will show the intro video, then reboot.
I tried binhacking the 2_dp.bin and 1st_read.bin, and changing the maigo.bin and sgdpldr.bin where is says 6EB0 0000 to the correct LBA. I don't know what I'm doing wrong.
Can someone please help?

Thank you very much,
