Small soldering projects like this you need a 15-35watt (max) soldering iron, 60/40 rosin core solder, some flux or soldering paste (big difference maker in soldering but DO NOT INHALE that crap).  

For desoldering: some desoldering wick (or braid) or you can use a desoldering iron with pump (should usually be sold at 35w range in radio-shack).

And most important of all keep the iron clean. I love to use on of these tip cleaners, (http://www.ebay.com/itm/271183421738?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649).

These are thing I use for my projects. Battery replacement (minus iron heat up time) just under 5 min ;D.

You don't need all of that for just doing batteries. Flux you can definitely do without as long as you're using lead/tin rosin core solder. If you're using lead-free, well stop using it because it sucks beyond belief and you'll need to heat that crap to like a thousand degrees before it starts to flow. No need for wick or desoldering iron in this instance. Put the tip to one of the battery leads, then just pull it out when the solder has melted.  Repeat for the other leg.

Obliviously you don't need all that for a battery as I highlighted my point in red just to clarify. Just illustrating a "tool kit".

Just replaced the battery in another game, a personal favorite: Lufia II

Got it done in about 15 minutes, most time taken is bending the holder's pins into the right spot.

It's not hard people :D

If there's a demand for a video, let me know, I could make a small video and point out what to do :)

That would be awesome. I have several games that won't save anymore, including Earthbound (though I would be kinda nervous changing out the battery on that game), Illusion of Gaia, Tecmo Secret of the Stars, and Super Mario RPG
BadChad:
Chances are you may lose your saves when you remove the battery, but that's not always the case. Not exactly sure what it depends on (maybe depending how much juice is still left in the battery your replacing and how quickly you can get it done) but I have swapped out the batteries on a few games, and couple of times to my surprise, the saves were still intact. Could have something to do with the energy from the battery not completely de-charging from the board before the new battery in fixed in?

Either way, I wouldn't count on it, but its possible. With that being said, swapping out a dead battery in an NES/SNES cart with a clip was the first time I ever used a soldering iron. And after a simple youtube tutorial and gathering the few things I needed, I was good to go. It's pretty damn basic and not much is needed. And from there I've gone on to do more cmplicated things like installing region switches in my genesis, mod chips in my Saturn, audio mods for my NES and various Neo Geo MVS repairs with very little worry and issues.

It's a good starting point to get anyone familiar with the basics on soldering. And if your worried about damaging the game (which isn't exactly as fragile as some might think) you can always try a shitty sports game as suggested. All in all, a very simple project to do. But I guess this kinda stuff might not be for everyone...

I might give it a try on some crappier titles. Im just not use to soldering but I can see if its something I can get into
