I have not had a chance to examine other versions, so I don't know about them, but here's the deal with GTA 3 "U.S. Version" ...

1. The 2 CD Disc RETAIL version has SD2 (v2.51.021).
2. It has NO serial number, much less imbedded.
3. It will 1:1 fine with normal SD2 settings using CloneCD and the usual array of suspect burners.
4. UnSafeShit 2.51 will NOT crack it, it will exit with an error.

BONUS:

For those that want/need it, here's a list of cheats and what they actually do:

Type in the following codes while playing for the desired effect:
