Link Goes Invisible in LA DX on GBA SP?! Please help!

Hey guys, this is my first post on Zelda universe... and I'm glad to be a part of this great bunch.

anyhow, I've had this reoccurring problem with LA DX... Every time I try to play the game, link will go invisible after a short while!! all you see is his shadow and sword swing!

This unfortunately makes the game completely unplayable! Now, I thought it might have been the game itself... but I tried 3 different DX game cartridges on different GBA SP's and still had the same problem! I even tried it on the Gameboy Player for Gamecube and still he turns invisible! I really don't want to have to play it on a GBC system.. theres no light!

so now, I bought the plain old LA original...not a bad game by any means, but If I can play this great game in color, why should i waist my time with an inferior version? (some will argue)

anyway, I've seen other people post this problem few and far between, but no one ever has a clear cut answer for them... can someone please clarify what is going on here.. and what can i do to resolve the problem.

I appreciate your time

I have never had this situation before... now do you think the problem is the game or the system?

If it's the game, I will gladly purchase it from you...

if you could see his shadow couldnt you work with that? or is it like he isnt even there?
