the shoal cave tides will stay the same tide permanately so you won't be able to get the shell bell other then that, u'll miss out on nothing.

The Berry Glitch wouldn't give the "internal battery is dry" message on startup...

There is an ACTUAL battery in the games?! Can it go dry just in general? How would you replace it?

Yes, there is, and yes, it can go dry; it's what keeps the clock running for time-based events, even when you're not playing the game. Not sure about replacing it.
As P-L said, though, it doesn't affect 99% of the game, though. Just time-related events.

Well, the berry glitch that happened with ruby/sapphire was a result of a counter on the battery, and could just be updated and not reaplced.

Fire Red and Leaf Green both lack internal batteries (their "time" is based on steps, last I checked)

Emerald doesn't have the berry glitch.


For the batteries to run out in such a way that you must replace them would take....years. They've made them a lot better.

But one day it will have to be done? Wow, where could you find batteries for them? Why are there batteries in them anyway? I don't get it.

I'd just like to add a couple of things.

1.There are screwdriver bits that will open those irritating Nintendo screws, search on ebay for 'gamebit screwdriver' or something along those lines.

2. Some GBA games have batteries, but the vast majority use flash memory to save their files. RSE use batteries to keep track of time. I can confirm that this technique will work on GBA games, because my Sonic Advance's battery died and I had to replace it. GBA games use CR1616 batteries, I think. You need a special screwdriver to open a GBA game, though. I think they're called 'triad' screwdrivers.

3. While we're on the subject, any NES or SNES games that have save files have batteries, and some N64 games probably do too. Once again, they can be replaced using this same technique.

4. Make sure that your game WILL NOT SAVE and it's not just a momentary fluke before you do this. If the file is still there and just not loading that time for some stupid reason, the moment you pull the battery all the saved data disappears.

5. If you're having trouble finding a replacement battery, try somewhere that sells watch batteries, because these kinds of batteries are used a lot in watches and stuff. Remember to take the old one with you to make sure you get the right kind.

The battery is like a watch battery - it's used to keep track of time. I think only Nintendo (by sending the cartridge to them) can replace it.

It is used every second for an eternity - it is used to maintain the clock time.

FRLG don't have a battery
DP does have one.

THE SAVES ARE TO FLASH CHIPS NOWADAYS. NOT BATTERIES.

Ah, okay! So Emerald has this chip too? After the battery has failed, it can still be saved right? That's the impression that I get from it... I was wondering, if I were to buy a brand-new Emerald/ruby/sapphire and never play (Just for a collection) the battery would still run out?

Yes, unless they made it so that the clock doesn't start running until you actually start the game. It would take a long time to run out in any case, however.

What I don't get about batteries are why they run out even though you don't use them. It's just weird.
