Hardware Supercard CF & 128KB saves

[Lumstar]

Is there a way to make GBA games with 128KB saves save? Strangely... The official patcher supports every type I've ever seen on DS, but only up to 64KB on GBA ones. That's just kooky.

An unrelated oddball is Metroid Fusion. It's files aren't 128KB, but are known to mysteriously not work.

Excuse the bump, please. This is important. If there isn't a solution to it, I'd really appreicate proof of the existance of a flash cart which can do 128KB save files in GBA mode.
