>Today, SNES emulation is in a very good place. Barring unusual peripherals that are resistant to emulation (such as a light-sensor based golf club, an exercise bike, or a dial-up modem used to place real-money bets on live horse races in Japan), every officially licensed SNES title is fully playable
I had to look up the 'dial-up modem' reference - apparently it's a Japan-only peripheral called the "Famicom Network System" that did in fact have software available that allowed for bets to be placed on live horse races.
