Shining Force II Easter Egg - Sonic Map

At one point in the game, you can find a GOLEM who is missing an arm. The map the GOLEM is found on is shaped like Sonic the Hedgehog. You may not be able to see it until the battle there.
To access the battle:
After you beat the game, "The End" will appear with the image of two crystals (Good/Evil -- blue and red). If you wait for approx. 5 minutes, a yes/no box appears with "Continue?". Selecting YES will take you to a "Final Battle" which has most (or all) of the bosses you've encountered during the game. You can see the Sonic the Hedgehog map there.
