Frequently Asked Questions


My controller didn't include an Allen key nor screwdriver. What should I do?
The controller uses a 2.5mm Hex Allen key to unscrew the knobs and case. If you have a v1 Yuancon, you'd need a size #2 screwdriver to open the case.
I ordered a Sound Voltex Controller, and it's stuck on "payment received." How long will it take to be shipped?
It takes one week to build the controller and 5 to 7 days to be delivered, depending on the country.
Is there a way to replace the paper inside the buttons?
Yes, you can either print or cut the paper in the following dimensions:
  • BT: 4.6x4.6cm
  • FX: 3.7x1.9cm
  • START: 2.1x2.1cm

After you've printed or cut the paper, you'll have to disassemble the controller now.

What should I do if my knobs feel too loose/tight?

If your knobs are feeling too loose or tight then check the video below.


My buttons gets stuck. Is there a way to fix that?

You can sand the edges of the button to help out. You can also check the video below on how to clean your buttons.

I received new buttons/springs and not sure how to replace my current buttons/springs.

It's relatively easy to install new buttons or springs. Check the first video for v1 and the second video for v2. If you're switching from stock to Sanwa, check the third video.



How do I reassemble/disassemble my Yuancon?

Check the video below to see how it's done. It can take a bit of time for the first time.

My controller arrived damaged, is there anything I can do?
If you've received any damaged parts, add and message yuan0312 on discord. You can also join the discord server at: https://discord.gg/4ncuRrq
Will customs charge me import tax?
This varies from country to country, so you'll have to look up the import taxes for your country. Some customers received their controller without having to pay taxes.
What's the difference between CMOD, XMOD, and MMOD?
CMOD: Constant Hi-Speed with no changes. (cheater mod)
XMOD: Multiply by BPM. (default sdvx hispeed behavior)
MMOD: Finely tuned speed that can be locked in to persist between songs. (sdvx floating hispeed behavior with double tap start/red number when locked in)
Is there a guide on a DIY SDVX Controller?
Yes, there's multiple guides on how to build your own SDVX Controller. There's an SDVX Controller & Pocket SDVX guide.
My Controller has no input. What should I do?
Try using a USB 2.0/3.0 port and make sure if you're using a USB HUB that it has enough power to run the controller. If that doesn't solve the issue, open the case and check if there's anything unplugged.
Is there a way to make the Yuancon buttons brighter? It's dim for me.
To make the button lights brighter, you can do so by disconnecting the RGB lights. Another way to do so is to short all the resistors marked "RL," but that may void your warranty.(Works on older cons that had leds with resistors. DO NOT ATTEMPT ON NEWER CONS). You can also buy a Roxy.
Does Yuancon support Linux?

Yuancon doesn't support Linux officially, but it can work on Linux with a few steps. There's three methods currently available.

Method 1:
Requirements:
  • Xorg display server
  • The controller must be in Mode 1

  1. Install evdev
  2. Create a file named 10-yuancon.conf in /etc/X11/xorg.conf.d/ containing these lines: 
    
Section "InputClass"
    Identifier "Yuancon"
    MatchProduct "YuanCon YuanCon Mouse"
    MatchDevicePath "/dev/input/event*"
    Driver "evdev"
EndSection
  3. Restart the X server or your PC

      ENV{ID_VENDOR_ID}=="51bf", ENV{ID_MODEL_ID}=="2101", \

You can use Silicone or Lithium based lubricant. DO NOT USE VASELINE OR WD-40.

How can I get a custom acrylic panel for my Yuancon, and how much does it cost?

If you'd like a custom acrylic panel, you must first design it and then send it to yuan0312 on discord. The cost of the custom acrylic panel is $35 at the time of writing. If you would like the SVG file for YuanCon, click here. If you would like the PSD file for YuanCon, click here.

I get an error on USC stating, "Could not open selected gamepad."
Try to unplug any gamepad device you might've and see if it works. If not, then head to the USC directory and open Main.cfg, then look for Controller_DeviceID and set it to 0, and that should fix it.
