Tested (all buttons, switches, and sound), plays fine, and in good cosmetic condition including a squeaky-clean battery compartment.  It does have some yellowing around certain section of the case, and there is chipped piece just above the main decal on the right which we've shown in the photos.   Also, the plastic cover for the screen does have some waviness, but this does not impair game play.  Please see photos for more details.  Operates on (4) 'AA' batteries which are not included.

Perhaps a good option as a placeholder in a growing or functional collection.  

Thanks for looking, Happy Gaming, and GOD Bless!!!
