Nulldc 1.0.6 music a little choppy and off and on freezes. How do I fix this problem?

I have nulldc 1.0.6 with sonic adventure and the game works pretty good but it freezes off and on. It The music and sound also gets choppy too. Other than that the games run at a good speed despite the freezes that happen off and on. How can I fix this problem?

My computer specs are

Dell Optiplex gx 520
P4 1Gb ram
80 Gig hard drive
Intel 82945G Express chipset family

I tried chankast and nulldc 1.0.4 but the portion of the game is blocked out with a black screen. I can only see half of the screen when I load the game so I left those emulators alone

Buy a Dreamcast

Dreamcast emulation is not perfect and your system is under par for Dreamcast emulation to start with.

The upside is most Dreamcast hardware can play CD-R burned games with no tricks or chips
