It all depends on your choices you make as a trainer, which will vary from hours to days to weeks. The quickest way to beat the game is, of course, through the use of a cheat device and this will take a mere 5 minutes or so. Aside from that, the only quickest way is to play Yellow through Pokemon Stadium and use the speed 3 mode. This will take you about 45 minutes at the quickest. On a regular gameboy, it takes about 2 hours at the quickest. These last two means you must train only 1 Pokemon and must avoid as many battle as possible.
