I have tried several different versions and hard drive installed of Zany Golf, but it always freezes/crashed after level 3. I used to play the whole game before, without any issues with previous versions of MAME some years ago. I don't know with which version this game broke.

Play Zany Golf on Apple IIGS with any ROM. Result is the same after completing level 3. This is playing the hard drive installed version from WhatistheIIGS site. Same result is with the floppy drive version.
