Yeah the PC looks clearer... But... It can just be that it's easier to take a screen shot on a PC then on an N64... Also it would matter what kind of graphic card you have AND if you have an expansion pak on your N64 (which I do).
Good news is that PC games are usually (or relatively quickly become) much cheaper than N64 games! I mean I bought Racer & TPM together (it was a 2 pak) for 25$CAN (which is like maybe 17$US on a day the Canadian dollars isn't too weak, but that's another story all together)... Racer, because I bought the N64 version as well (please, do not ask why) was 40$CAN (you do the math for US currency). So kewl... PC is good!
You can do it your own way
Just as long as it's done just how I say...
