I've been thinking about this for a couple days and have came up with an idea that I think is pretty cool. The rules are simple, you collect items and defeat dungeons to earn points, powering up your hero will help you score higher points.
The original Legend of Zelda for NES is one of my favorite games and fits nicely onto the Bally Mystic game. Zelda has 9 dungeons and each dungeon has a special item that you collect in it. You upgrade your sword and shield twice each and finally there's a bunch of power ups that you collect throughout the world.
Mystic has 9 drop targets, each one represents one spot on the tic tac toe board in he center of the playfield. The drop targets are either pyramids or eyes on the grid and you change them by hitting the pop bumpers. There are 4 star lanes and a captive ball that gives a multiplier.
The 9 dungeon maps of Zelda all fit together into a tight box. That will be used in place of the tic tac toe board in the center of the playfield.
Each drop target will represent one dungeon and/or it's associated item. The dungeons drop target will be as close as possible to each dungeons location in the map on the center of the playfield. The inserts will have a 8bit picture of each item and/or dungeon number instead of the pyramid and eye. To switch the drop target between dungeon and item you will hit the tri force pop bumpers.
The spinners in Mystic score 10 pts and after you get the ball in the saucer at the top of the playfield they score 1000pts. I thought the two spinners inserts could get graphics for the compass and map; two of the most common things you acquire in each dungeon.
The 4 star lanes ( 2 at the top beside the saucer and 2 in the inlanes by the flippers. ) will be used for weapon upgrades. The top two for the white sword and master sword. The bottom two lanes for the wooden shield and large shield.
Finally the captive ball would be used to collect the final items from around the world. Each inline insert would be an item. First a bomb, then the blue ring (x2), power bracelet (x3), red ring (x4), health potion (special), and the magic key to complete the row.

Lvl 7- Red Candle
Lvl 8- Magic Book
Lvl 9- Silver Arrow
The backglass could be simply the Start screen from the game. The cabinet graphics could be something simple like the NES games box art.
I'm fairly new to the pinball hobby but I feel the this project is almost within my skill set. I will need to learn about creating the graphics for the playfield although having everything available from the video game and having it in 8bit should make it easier. I will need help with creating the playfield plastics. Although I did consider making them out of perler beads to have them look 8bit-ish. Finally the sounds. I think I can figure out how to setup and install an mp3 trigger system, but assistance would be awesome.
I don't know how quickly I will get to this protect, but it would be a fun one.
