The lion king dos game running slowwwwlyyy

hi.
About 20 mins ago i downloaded the lion king dos game, only because i remember really liking it a LOOONNNG time ago, but for some reason it runs really slowly. I tried another old favourite (the blues brothers) and that worked fine.

This is the first time ive tried playing dos games on a xp pc, so i havnt got a clue if anything can be done or how to do it.

If you have any ideas please help!

thanks.

btw i downloaded it here (CLICKY)
