NBA 2K Not playing properly in DC Emulator

Hi, everyone new to the forums..

I have a problem whenever I load and attempt to play NBA 2K... the game will play however there is static like sound and also the play by play announcer will say one word and then the game will repeat that word for the duration of the game.

(E.g. He shoots, shoots... it keeps repeating all game)

And the sound is very static like, the game is a CDI file and it is self-booting.

Is there any fix for this or any settings that I can adjust to make the game play and sound properly?

Sorry, no can do with an answer concerning PIRACY (site rules)...

...Please feel free to purchase a Dreamcast console alongside the original game, since they are cheap enough to purchase.
