Nope, I only have:
Sapphire (Currently in the process of beating the Elite Four)
FireRed (Started again because the save data was corrupted or something)
[FAKE] Emerald (Yeah, it's not real, and deletes data when you play a different GBA cartridge so I never play that any more)
Colosseum (Completed - ON A DIFFERENT MEMORY CARD)
XD (Completed that, purified Lugia as well)
PMD Blue (But I gave that to my friend)
If it counts, my cousin also lent me his Ruby so I could train his Pokémon up a bit because he wasn't doing too well.
