Good call: the Genesis probably never takes 1.3ish amps like the adapter says (something like that) and you may decide that you won't need to do the backlighting mod to get the minimum playtime you decided on

It's also for power spikes. The PSOne comes with a 2A adaptor, though it only draws 850mA on average. I hooked it up to a nice regulated 3A supply and it was current-limiting - the power draw spiked to over 3A on occasion, especially during startup. So be careful hooking it up to an ammeter - most have 3A fuses.
Like Spongebuell said, amps are drawn, not pushed. Also, batteries have capacities given in Ah, amp-hours. Remember all those times your science teacher harped on you for not keeping your units straight? It's important. One amp-hour = one amp for one hour, or ten amps for six minutes, or ten milliamps for a hundred hours.
Don't use alkalines for these portables. Alkalines have a high internal resistance, and you'll see a significant voltage drop if you draw more than a few tenths of an amp. Lithium is better, and NiMH batteries for RC cars are often certified for 30+ amp continuous draw.
