Smash Controller scans and disassembly

Post by Skaarg »

I received this back in December, but was quite busy to get pictures/scans done. After posting over on Sonic/SEGA Retro andlabs asked me to post this over here so here I am for the first time.

For those that do not know Whac-a-Critter (or Mallet Legend or Mallet Legend's Whac-a-Critter, whatever you want to call it) is a whack-a-mole type game where you press the d-pad direction of the hole (or none for the center) and a button to use your hammer. Well Realtec themselves and 3rd party accessory Innovation released the same controller (both versions say Realtec on the controller, I have the Innovation box).

These boxes were all in about the same condition. This was the best one I was able to pick from so the scans are about the best quality I can personally get.
Box Scans:
Front - "For use with SEGA Genesis and SEGA Megadrive" so it was obviously meant for multiple regions. SEGA Retro says the game only came out in the US though. Has anyone ever seen a EU or JP (unlikely due to no Japanese directions) release for this game?
Back - "Designed for years of bashing and thrashing" becuase the game is so god awful? "Whac-a-Critter and Video Simon" Well Video Simon to the best of my knowledge never came out.
Inner Flap - This flap is inside the box over the controller. These directions don't get much simpler than that. =P
Top/Bottom - Just says Smash Controller.
Left Side - Back and Inner Flap info in other languages
Right Side - Back and Inner Flap info in other languages

Controller Pictures:
The Controller - Fairly simple design. No pause or start button however. The game just progresses to gameplay by pressing any button. There are no settings or anything.
Controller Bottom - Again it doesn't get much more plain than this. There are 4 screws hidden under the pads. I really don't know why they put the pads over the screws when there are circles on the plastic that show where they are supposed to be...
Controller Board Top - It really doesn't get much simpler than this. The IC chip is just a Motorola SN74LS147N.
Controller Board Bottom -Again there's not really a whole lot to see here. =P

If anyone else wants any other pictures or information feel free to ask.

Edit- fixed copied bbcode...

I planned for years to try to make my own since I knew it wasn't difficult.

Hello to everyone! I'm a newbie here, and English is not my first language. Sorry for my occasional errors in text or in writing... But anyway...

I know that this topic is 13 years old, but this is only one place on the internet where this controller has been disassembled and pictured by the Skaarg.

I have a big question for the author of this post and excellent photos of the guts:

Skaarg, Please, please, please! Gave us a pinout of this controller.

1) To what pin, exactly in the plug, does every wire from the PCB go?

2) How many pins are used in the plug? (Taiwan manufacturers back then populated only the exact number of pins to reduce the costs.)

3) Couple photos of the plug itself may be very useful too. (to see what kind of pins are used) (if it's feasible)

PINOUT PLEASE.

I'll be very appreciative of this. (Like others, who may find these forum messages in the future)

A little story of my struggles:

I recreated this controller, from the ground, with your photos of the PCB, from this forum, a couple months ago. I took buttons from a disassembled vending machine. Knowing that "Everdrive", which I have, can't load "Whac-A-Criter" I ordered a new "old-stock" game cartridge from eBay (it came to me a month ago from France). I have a "self-made" laser CNC-cutter, and designed and cut a case from yellow acrylic (that I found in the trash of a closed Big Mart) for this controller. I ordered ICs from a chinese "express" site. And everything seems ok, until I "crash" into the wall of not knowing the pinout.
