apparently there's a variable resistor you can turn to adjust the contrast of you GBA (it's hidden in the back), was wondering if anybody tried it.

My feelings about the screen sucking must be on target. Man, I need to go check one out.

The screens fine as long as you have decent light. You don't have to have flourescent light, or even sunlight. Sitting a couple feet from a plain old lamp works just fine. Especially for bright, colorful games like Mario and Rayman.

I don't reccomend trying this as it probably won't do enough good to justify the risk and the voiding of your warranty. Anyway here's a picture I found at pocket.ign.com

Call me crazy but if they wanted a contrast control on the GBA don't you think they would have made it easy to get to.

I found mine and poked that hole. It makes the GBA kinda 'wavy' and 'washed out'. I only have Mario, so theres no real point of adjusting the contrast.

Here is what that control does straight from Nintendo:

A positive and negative voltage controls Liquid Crystal Displays (LCDs). The "contrast control" that you are referring to is actually a flicker control. The adjustment is used to synchronize the positive and negative voltages. If these voltages are out of adjustment then the LCD will no longer respond correctly. The result will be an excess charge built up in the liquid crystal and permanently damage the LCD. The excessive charge gives the appearance of a brighter screen because the liquid crystal is not reacting properly to the voltages applied. When the adjustment of the voltages is correct the changing polarities will not allow a charge to build up, which prolongs the LCD life.

This adjustment is set by the manufacturer or must be performed by a qualified Nintendo Technician using proper equipment (Proper lighting, special tools, test equipment and software). Adjusting the flicker without the proper tools and lighting will put the voltages out of sync and may cause damage to the unit.
