Hacking Migrating Pokemons from GBA to Platinum with oficial game card

[BigBolt]

I have a original Pokemon Platinum game card in slot 1 and a EZ Flahs 3 in 1 in slot 2 running a GBA rom (Pokemon Fire Red).
I´ve got all requirements to unlock Pal Park in Pokemon Platinum so I could migrate pokemons from GBA to DS.

But nothing is available for that. (The option "Migrate from" in the start menu screen isnt showed).
So I guess the game card wont recognize this rom (i´ve tried even with others gba roms, but no success).

My question is:
Is there any way to patch this rom for slot 2 ?

http://gbatemp.net/index.php?download=1984 You need to patch your Pokemon ROMs for them to be able to see the 3in1 as an original GBA Pokemon game. Note that the patched ROM will not be able to trade with original GBA Pokemon games anymore. The Dual Slot feature however, will work with both 3in1 and originals.

I don't think this could work because he said he has an Original Pokemon Platinum Game

He doesn't have any slot-1 flashcart at all? What did he write FireRed onto the 3in1 with then?!
