As others have said already, the sound routines of many games usually run in 
the vertical blanking interrupt (VBI), which is 60 Hz on NTSC machines. 
Nothing you can do about it, except rewrite the game code or convert your 
NTSC to be a true PAL machine (both options are very hard). I enjoy my NTSC 
SX machine as it is, and I like to run the intro of Skate or Die on it! The 
music *really* rocks on this machine, very unlike the slower sound on PAL 
machines. EA made a bad job in converting this NTSC game to PAL, they slowed 
down the music!

There can be two problems: 1. the contacts of the AR are dirty. Remove the 
cover, and rub the contacts with a pencil eraser (with the more abrasive 
side) until they are bright and shiny again. This helped a lot for me, before 
this treatment my AR would work fine on any C64/128, but not on an SX! 2. The 
fastloader of the AR is PAL/NTSC specific. If your AR is PAL only, go to and grab an AR or RR ROM that works on NTSC and burn it to EPROM. 
Or buy a Retro Replay ;)
