You will likely need a new cartridge. If you have an older version (Gameboy/ Gameboy Color/ Gameboy Advance) you can try replacing the battery. You will need a special screwdriver to open the cartridge, and good soldering skills to do it, though. Also, make sure the contacts are free from corrosion and dirt. Last I knew there was some really good cleaning stuff at www.stoneagegamer.com DO NOT just blow in it.
If this is a result of the MISSINGNO glitch in Red/Blue don't waste your time, the SRAM (the chip that stores the game save) is likely damaged.
gamestop
on Pokemon silver press the start button and click save if it doesnt work then your internal clock is broken and you need to bring the game to gamestop and they will fix it
yes garatina
You may need to restart your game, or go into the room in the Pokemon center where it makes you save.
no it doesnt corrupt your game but it does freeze it but dont worry about your save :)
Sounds like either your save file or the cartridge itself has become corrupt.
Definitely Thundurus. You can get 2 Master Balls in Black and White. You should save the second one for shinies or event pokemon.
It doesnt
yes they should do and if they don't use the old gold & silver trick and save 3 times
it just stops saving doesnt save and ull be where u left off the last time u saved..............i think.just try not to do it.
Save your game also have a strong water type Pokemon with you and a Pokemon that can make groudon sleep.
Your game is either screwed up or faulty/fake. It should normally save because mine does.
