Jap House of the dead won't run with Utopia boot disk?????
 

I have managed to make a Utopia boot disk that seems to work OK. I bought a Jap copy of House of The Dead 2 (cos it was a lot cheaper than the UK version!) after being told that the game will run using the boot disk.
I run the Utopia disk, replace it with the game when told, I see an image of the game disk spinning on the screen then everything goes black??? No sounds, no GD access, nothing?
What's gone wrong?
