I have a copy of Crash Dive that for the longest time I thought was PAL, but when I tried it on my 2600 today it looks like it might be NTSC. The problem I'm having is that my monitor does PAL as well as NTSC so the stable picture doesn't mean anything so I have to go by color. What color is the ocean supposed to be? Is it supposed to be blue or murky green? I've seen both when I looked for pictures on the net. Mine is a nice blue color.
