Summary 01965: driveyes: [debug] Access Violation
Description I know this is a GAME_NOT_WORKING, but it doesn't crash with a x86 build and right now it should be broken like the other namcos21.c games, but it does crash before that with a NULL pointer access.

Here is the call stack:

Fixed in 0.169, I didn't take the time to check what change actually fixed this.
