Hello guys, apologies for this late post. Here is a pic of the bottom/interior of the FightStick PRO. The stick actually started shipping this morning after this weekend's orders processed.
First off, Mad Catz does not condone you opening up your stick/voiding your warranty unless qualified to do so. If you feel you are qualified, go for it, just know you voided your warranty and we are not obligated to warranty your product.
Alright, on with the show... First off! We wanted to take a more secure approach for the stick. As you know there are no top/hex screws on the FightStick PRO, instead there are TEN (10) screws on the bottom. Two different screw sizes. This may make people whine at the sheer thought of it, but hear me out.
There are smaller screws (same size as the ones on the SE) and then there are the 4 rubber feet held screws (bigger). Obviously the 10 screws total is to keep the bottom panel secured, however, the 4 rubber footheld screws are enough to keep the bottom plate on/secure. So modders will most likely eliminate using the smaller SE style screws and take them out completely. From there, you have 4 larger/standard size screws that are big/won't strip and easy to take off. So with modding in mind/and ease of use. 4 large standard size cross screws and you're in. Here's the pics:
Bottom Panel. You can see most of the screws here (the others are hiding under the bigger ones).
The larger screw.
The smaller (SE Style) screw.
Now you have access to the interior. Swapping sticks & buttons should be a breeze. If you need to gain access to the top panel/artwork area for an art mod, then you'll have to go further and unscrew the easy to find screws (notice the red gunk) around the frame of the FightStick PRO. If you are familiar with the SE FightStick, the artwork is applied in the same manner. You don't have to take the stick apart, but you can if you want.
The bottom white frame was designed in mind with a thin layer of plastic, perfect for mounting 'other' PCB solutions.
The Start & Back/Select buttons are a lot more accessible than the TE FightSticks. As you can see in the picture. Also, the PCB area is underneath where start/select are.
Sorry this is just a short/quick look into the insides. I didn't have much time to pull one apart today. Hope this helps somewhat.
