Gecko OS 1.92 and memory card size

[GolfDude]

I use gecko OS so i can use codes (texture and music hacks) for smash brothers.. when i  use my 2 gb card the codes work fine, but when i use my 8 gb card, it says  i have too many codes and it wont apply the codes even though it  the same file as the one on the 2 gb.. any ideas why  it wont let me use the 8 gb card  for codes?

i know smash bros can only read up to 2 gb cards, but why would it be an issue for gecko?
