Release id #45809 : Bomberman C64

hello all,
I noticed that Bomberman C64 sometimes crashes on certain C64c, apparently at random (there's no specific point of the game where it crashes). In particular I have 2 C64c with latest board revision (no color RAM chip) where it crashes. At first I though it was just because these C64s were faulty, but I can run any other sw without problems (I ran several demos and games).

Furthemore, I have just noticed that Catollica (Catollica) crashes also at random on one of these c64c. Have not tried on the other one yet.

This makes me think the Skull (coder of both Bomberman and Catollica) used an unstable opcode.

Anybody noticed this?

bomberman c64 uses vsp to scroll screen so its possible that your c64 doesnt like it.

see here: VSP/DMA delay compatibility

mmh, I though about it, but:

- I experienced this problem on newr C64s and the mentioned thread talks about old C64

- I could run a lot of demos with no problem (even using VSP, I am succesfully running VSP&IK+)
