So originally when I routed out the NES cartridge, I routed two cartridges.  One was the TMNT game and the other was a Friday the 13th game.  I needed a second in order to route out the centers to some of the letters and save them for later. Its now later and I'm having to insert and adjust the centers to fit...

Some of these pieces were rather small.

At times I felt like I was playing operation.  Cutting out the stickers so they lined up perfectly on these small parts was a nice challenge.
