Paperboy loads extremely slowly

This is reproducible in the original KEGS emulator also. If you load Paperboy, after the title screen appears, the next screen (the newspaper) will come up slowly, line-by-line. The music is also affected and becomes drawn-out beeps.
I did some experimenting, and the game loads with MAME, but the music is totally missing. There are only sound effects.
I can get it past this if I rapidly toggle the speed with the right mouse button, but eventually it will still freeze and start drawing a line at a time again. I have to start toggling it before the game boots.
It seems to me like the sound chip(?) is controlling the speed of the CPU. Every time the main tone of the music changes, another line gets drawn. As long as the tone stays the same, so does the screen.
