Yes they all look bootleg to me. If you compare the sticker online you will most like find subtle differences. You can also open the case and look at the board which will tell you for sure if they are real or not.
Also Links Awaking and both Oracle games never released on GBA they are all GB/GBC games.
Links Awaking had two releases. The original Links Awaking is a GB game for the original Gameboy and Links Awaking DX is a game for the GBC with extra features and colour support. Links Awaking DX came in a black cartridge instead of a silver one.
