what protection system is it???

[BOT]

Assuming you have the NTSC version SLUS-01087
this game has protection that detects a modchip and refuses to go further.
The original would have done this as well as the copy.
You will need to get the patch and copy the cd using CDRWin, applying the patch to the .bin file before burning.
