I'm playing through Link's Awakening myself, but I am playing the DX version on my GBC. Still need to be under lots of light to play though.
I can help you with that:
A few years back, Nintendo put out this amazing little machine called the Game Boy Advance SP.

It can play GBC carts, and-- best of all--
it has back lighting.Get yourself one of those, and you'll be good to go.
Preferably one of the pearl blue or pink ones, which feature two levels of back lighting brightness.
No need to thank me, by the way-- I'm more than happy to help a guy out.
