Qanba Obsidian & Perl customization notes

In this issue, I would like to explain some points to note about customization of Qanba Obsidian & Perl.
Qanba Obsidian & Perl

No.1, Threaded buttons are difficult to install.

The home-use FightStick has a screw-on button that is more difficult to install than a screw-on button.
Screw type buttons are recommended for home FightStick.
For Qanba Obsidian & Perl, we do not recommend screw-on buttons.

Here is why we recommend the screw type.

  • Easy to use without worrying about claw breakage when replacing.
  • Suitable for home use where replacement is not frequent because it can be firmly fixed.
  • Buttons do not pop out even under heavy operation as long as they are firmly fastened with screws.

Here are the advantages of the framing type.

  • Installation is easy because all you have to do is push it in.
  • Easy to remove by pushing the claw when replacing.
  • Suitable for amusement facilities where frequent maintenance is required for the above reasons.

Please see Obsidian photo for button position.

The circuit board is faintly visible from the △, R1, and L2 buttons, just by peeking at it from above.


Due to the position of the backside and the board, if you attach screw-type buttons to the △, R1, and L2 buttons, they will hit the board and capacitors.
The current version has been modified to be silent and the interference is a little better, but we still do not recommend it.

Please see the following photos of Perl.

The board can be seen from the △ button just by peeking at it from the top.

On the back side, due to the position of the board, the R1 and L2 buttons have more space than the Obsidian, but the △ button has even less room, and it looks as if it might rub against even the built-in type.

There are positions where it is physically difficult to install the buttons, so when replacing buttons on Qanba Obsidian & Perl, choose buttons that are retractable.

2、Structure of audio connector that is prone to disconnection

The audio connector is wired from the main board on the top board to the audio connector on the bottom board, so there is a risk of disconnection if the bottom board is removed too vigorously.
After removing the bottom board screws, be sure to check the audio connectors.

Obsidian is shown above.

Perl is the same.

Don't forget to unplug the 5-pin wiring before customizing, as it is easy to leak when reassembling!

As a side note, if you use the earphone jack with the LEDs lit, the current will be abnormal.
Please do not use the earphone jack while the LED is lit, as it may cause an abnormal current flow and damage the earphone jack.
It may be better to treat the earphone jack as if it were not there in the first place.

No.3, The plastic bottom plate material tends to warp easily.

This is especially likely to happen with Perl.

This is normal Obsidian, which has almost no warping.

A warped Perl bottom plate, you can see that it is slightly convex.
If you try to install this, it will be difficult to frame it, and it will look like the picture below.

It is floating because of the warp. In this case, let's fix it and screw it in place so as not to damage it.
It is better not to disassemble more than necessary.

These are the notes on Qanba Obsidian & Perl customization.
Thank you for reading!
Have a good acct life!
