Don't worry. It takes each day in the game and you can choose to save it. (You have to play with your cat for until you have to go to bed in the game.) I just figured it out myself!
yes
They save on the game cartridge/ Game itself. Not the system.
no
No, the DS cannot play Gameboy games.
You aren't able to save game files to a action replay, gameshark,etc.
All Gameboy Games can save if the battery is working. If the game stops saving, you may need to change the battery.
Once you deleted your game save, it cannot be recovered.
Are you sure they are authentic, and not bootlegged, fake cartridges? Authentic cartridges store save data on their internal flash memory - while they do have batteries, this is to regulate the in-game clock, which the console itself does not do. Bootlegged cartridges almost always use a (cheap) battery-based memory system too. While it can save and load properly initially, they battery soon runs out, and the cartridge is unable to retain save game data.
what you have to do is save before you battle a legendary and if you kill it turn off your DS or Game Boy Advancedand restart from the last save point.I remember using this method when it first came out on Game Boy Advanced SP ahh the old life
No because of 2 reasons 1 because once you migrate-that's how you get Pokemon from gba to ds YOU HAVE TO SAVE FOR THE PROCESS TO WORK 2 beacuase you have to save after words HOPE I HELPED
The battery thAT COUNTS IN THE GAME RUNS OUT SO THERES NO TIMER anymore and you cant save anymore.
No, no you can't. When Balloon Boy launches into the sky, there is nothing else you can do but go on with the game.
