Reddit reviews Arcade1Up 12 in 1 Interface Board

Yeah they are going to be a constant item being sold, they just keep selling out really fast. They've been selling them on Amazon in batches of 500 and they're selling out in an hour or two so just keep checking.

Interface Board for 12-in-1

https://www.amazon.com/dp/B07NKJ3SKH/?coliid=I2COG8BI2O4M9I

Remember with the 12 in 1 he will also need the interface board (which adds another $12 to the cost) if he only plans to replace the spinner. I bought the 12 in 1 mostly for Tempest as well and the Thunderstick was well worth the money spent. I've replaced the buttons, trackball, and spinner and the spinner is easily my favorite addition.

I purchased a converter board from Amazon. You can hook up to 3 spinners/trackballs to this board.

Thanks for the link! It isn't showing up here but I grabbed it from your comment history. Thank you!

THe 12 in 1 addon board for the GRS spinner would work - You plug in the trackball/spinner and it converts it to be used as a USB device for PC/RPI ( https://www.amazon.com/Arcade1Up-12-1-Interface-Board/dp/B07NKJ3SKH/ref=pd_rhf_se_p_img_2?_encoding=UTF8&psc=1&refRID=GQ3C5NHMD4359VXSC8JN)

Forgive me for repeating anything you may already know.

For the buttons and joystick, you need a USB encoder. This or similar:

https://www.amazon.com/EG-STARTS-Encoder-Controller-Joystick/dp/B01L8K21CK/ref=sr_1_5?keywords=arcade+usb+encoder&qid=1574973074&sr=8-5

Connect the buttons and joystick to the encoder, connect the encoder to the pi through USB. When you set up retropie, you will be prompted to assign each button for the pi interface.

For the GRS spinner and trackball, you will also need the GRS "12-in1 board".

https://www.amazon.com/Arcade1Up-12-1-Interface-Board/dp/B07NKJ3SKH/ref=sr_1_2?keywords=grs+12-in-1&qid=1574973218&sr=8-2

The GRS spinner and trackball are both designed to plug directly into the stock Arcade1Up hardware. There is no USB connection on those devices. The 12-in-1 board gives you that USB connection. Plug the Spinner into the "P1" port on the 12-in-1 board. Plug the Trackball into the "P2 port". Use the micro USB port on the board to connect to a USB port on the pi.

The pi will recognize the spinner and trackball as a mouse - both devices will be interpreted as the same mouse input. But, that should already be set up to control left/right/up/down movements in any emulator. (Left/right only for the spinner, of course). So, you can jump right into centipede, or tempest or whatever you're using them for.

You may need to adjust the sensitivity of the trackball and/or spinner in each game individually until you get the right performance. There are threads about that on this sub. Here's one:

https://www.reddit.com/r/Arcade1Up/comments/cj1m4b/share_your_trackball_speed_settings_in_retropie/

In that thread, you can ignore where it says to change the speed. As is clarified later in the thread, the speed settings don't matter - only sensitivity.

I'd love to have a spinner too, but regrettably, the only way to go about this is to roll your own with real arcade parts, or a reasonable facsimile.

That costs over sixty dollars, plus a wooden container and whatever buttons you'll need to complete the build. It's annoying, but the MacGyver'ed solutions I've attempted have been unsatisfactory at best.

It's probably going to be the same deal with a twin stick, but that may not cost as much. I imagine two arcade sticks, a few buttons, and an encoder (along with another box) would do the trick. Maybe disassemble an old arcade stick from Hori or MadCatz, take out most of the buttons and replace them with a second stick, and wire up the action buttons (triangle, cross, square, blue diamond, purple horseshoe, et al) to the second stick for best results.

You can use Glen's 2-in-1 Interface board if it's the same connector as the V1.

The stock "V2" A1U spinner isn't compatible with the interface board (won't output via it's usb port) according to the interface board amazon page:
