You want really play via emulation?  A solution could be to not use emulators, i think you can find very good port of this game in Native PC code for DOS.  
I remember i had a very good pacman which worked perfectly on my old PC XT 8088 4,77MHz!  and it becomed unplayed when i used the turbo switch of my PC to speed up to 8 Mhz!
