the Flash Advance Linker, it can simply be plugged into the Gameboy
Advance and it will act like an original game - there is 100 percent
not any difference!

data. This means once you've opened a lot of levels or you got
some extra points in your game, you won't need to start from the
scratch - it will save the game status just like an original cartridge
with the game. Savegame data can be stored on your local PC Harddrive
too, so you won't loose any data when you are using the flash
card for other games.
