Chicken was used in n64 to activate a level where you play as an at-st, and the level is a huge green field with villages on 2 corners, a base (protected by a force field generator), and other small stuff. It's color matches the color in Chandrila. I'd REALLY enjoy playing that level with say...a y-wing or a x-wing.
RADAR-this code made the radar more realistic by making enemies that are higher than you dimmer than the ones below you.
Credits-allowed you to view credits, nothing big.
I believe there's that atst level hidden deep within rogue squadron 3d waiting to be discovered, along with the radar code...
ummm we already have the atst code for the computer and I'm pretty sure the radar equilvilent was released as well.

I haven't heard or read of the radar equivelent. ATST code of course was in their, but i'm sure they wouldn't have taken the precious time to remove the atst minigame!!!
