Total charge of battery:
220mAh from 3V to 2V
220mAh = 0.22Ah
0.22Ah * 3600s/h = 792C

Current drained by Very-Low-Power SRAM chip in standby mode (I've seen those in several NES cartridges, some may only have Low-Power SRAMs, though):
typically between 0.3uA and 0.4uA when continously in standby mode
0.3uA = 0.0003mA = 0.0000003A
0.4uA = 0.0004mA = 0.0000004A

Discharge time (in both cases):
792C / 0.0000003A = 2640000000s
2640000000s / 3600s/h = 730000h
730000h / 24h/d = 31000d
31000d / 365.25d/y = 84y

792C / 0.0000004A = 1980000000s
1980000000s / 3600s/h = 550000h
550000h / 24h/d = 23000d
23000d / 365.25d/y = 63y

Taking signifficant digits into account:
60y min for typical drain, 80y max for typical drain.

...In other words:
70 Years +/- 10


But as somebody mentioned, the battery itself and the diodes blocking off the rest of the power lines has some fractions of uA leakage (internal leakage of battery varies widely from battery to battery, and by temperature), so these calculations may be a little too optimistic. With 1uA of leakage (which is quite a lot for Lithium coin-cell batteries), the estimated lifetime will be less than a third of the calculations.

Please. I may have said Europe, but what I was reffering to was where I live in Europe. It may have been popular on mainland Europe or in the UK, but nobody I know where I live have/had one as of I know. The Amiga 500, on the other hand, seems to have been very common here. It may have been a little before my time anyways, so I'll admit I'm not exactly the right person to judge. I did state in my previous post that the reason I included NES was of personal interest and not due to it being popular or not.

I may have been a little narrow-minded with that last comment, but it was about 2 AM (local time) when I wrote it. I did absolutely not intend to offend anyone with it.

None of those had any signifficant popularity in Europe at all. Here the home-computers ruled the gaming market till well into the 90's. Allthough I do mention the NES and SNES, that's because I have had some interest in those systems at some points in time.

I wouldn't put too much faith in satire either.

All he says is that he has a very closed definition on what next-gen is. Defining such a thing as "next-gen" is a paradox in itself, heck, even the original NES/Famicom hardware spans over two generations - Unchanged.

I'm not really playing anything obscure recently (Just started Ocarina of Time Master Quest - GC version), but not too long ago I did play something quite interesting: Elite on the NES.

This is one of the few NES games (if not the only one) that generates realtime 3D graphics with perspective, allthough the models are not too detailed (as soon as you exceed about 25 simoultaneous lines on the screen, the framerate goes down the toilet). It was only released in Europe, and therefore suffers from the PAL unit's slower CPU speed too, which is a shame since the graphics engine is one of the heaviest of any game to reach the system (it has to do a lot of translation to emulate bitmapping on the tile-based graphics hardware).
