Release id #9472 : Cop Killer

In VICE, the game (Wanderer´s part 2) crashes once it starts - anyone gets it to work?

It seems to work on CCS64 and a real C64, so there must be a fault somewhere in Vice :)

works here in vice 2.3 but it's true that sometimes crashes after shooting a target.

OK, thanks for trying out! For me it crashes (in X64sc) as soon as the first targets appear.

I bet it's a bug/wrong assumption in the code. It checks fror $d41b for random numbers, while music is playing... wrong move I'd say. Patch music with vice mon like this
> 1033 60
to stop the music and you'll see that it never "crashes" or better goes into this loop
.C:4031   AD 1B D4   LDA $D41B
.C:4034   29 C0      AND #$C0
.C:4036   CD D4 3D   CMP $3DD4
.C:4039   F0 F6      BEQ $4031
