I really enjoy The Flintstones gameplay, but I personally cannot stand the live movie actors stupid faces.
Replacing the translight with the alternate one with the classic cartoon characters is a must IMO.
There is also a playfield decal that does the same thing for the characters in the middle of the playfield.
Improves the look 100%, and is easily reversible.
The ultimate mod, would be the color DMD with the animations all redone with original cartoon clips, and the audio callouts as well. but that's just a dream.
