Hide cd media with GTA3?

i have just backed up GTA3 which is reported to have SD2.51 protection.

i have used a liteon 40x with CCD 4, using SD2.51 (no AWS) profile).

when i try to play the disc using my CD writer i have to select hide cd media.

am i right in thinking that the hide cd media option is required because i am using my cd writer to play the game ( i do not have another drive available).

what is this protection called and is there any other way around it other than “hide media”?

The game checks the CDR’s ATIP.
Here’s a link explaining ATIP:
