Zoo Keeper Isn't Playing With HyperSpin

[hyperfight]

When I run Zoo Keeper outside of HyperSpin with groovymame .178 it plays just fine. When running it through HyperSpin it appears ok at first, but after the nag screen the image folds in half and then plays in the background behind HyperSpin and I can hear slowed down/distorted audio playing from the game. Is there a setting that I might be able to adjust to get this to play correctly? All other games in my setup are playing correctly. Zoo Keeper uses a 256px resolution, so maybe that has something to do with it.

I have tried other versions of GroovyMAME with HyperSpin with a similar result. This is running on a Windows7 64 system.  

I am using Hyperspin 1.4 I believe.

Thanks for your thoughts.
