The saved data on a GBA cartridge is maintained by a small battery. If this battery goes flat, the data will be lost. If your GBA cartridge is unable to save, you will need to open the cartridge up and replace the battery.

Saved games on GBC and GBA are maintained by a battery, and this battery will become flat over time. Really the only thing you can do is order a tri-wing screwdriver, carefully open the cartridges and replace that battery.
It probably depends on the game, but most likely you'll need to replace the save battery.

if u have a GBA emulator just open File/ Save game and then chose slot to save...

Your internal battery, which regulates the watch and the save files, has gone dead.Using the instructions http://www.instructables.com/id/How-to-replace-the-battery-in-a-pokemon-goldsilve/ here, you can replace the battery yourself.
You can transfer the .sav file from the "Battery" file in No$GBA to a DS Flash Kart and replace your original .sav file with the .sav file from No$GBA. Make sure to back up your save file on your flash kart first! If you don't want to spend any money, or don't have a DS Flash Kart, you can't transfer them.
No, it should not delete the game file. Save files being lost for no reason is usually something that happens to counterfeit cartridges due to the battery-based memory.
the carterage battery ran out, unscrew hexagonal screw on back and replace the battery.
