Trackball - Big Middle and Big Right button illuminations (swapped)

newbie337 — Tue, 22 Sep 2026 16:17:08 +0000

Issue: Pressing Big Middle button lights up the Big Right button (and vice versa).
Trackball device has cool feature that the lights for the big buttons can be: Always on, On when pressed, or Off. This is accomplished on the LCD menu screen: Press small black button, Scroll trackball down to "Button Settings", Press Big Right button (red) and scroll trackball down to -- Lights -- section where Big Middle, Big Right, and Big Left illumination settings can be changed using the Big Right (red) button.
When the "Big Middle" setting is changed to "Always On" or "Press", the Big Right (red) button illuminates. Conversely, when the "Big Right" setting is changed to "Always On" or "Press", the Big Middle (green) button illuminates.

RE: iCode - paddle configuration on Atari 7800 - Fire1 or paddle button - missing in action

I’ve made a bit more progress. On MiSTer, I enabled the input tester and discovered that both ‘Paddle 1 Button’ and ‘Paddle 2 Button’ correspond to the B button. This explains why, when on the Atari 7800 button configuration you set ‘Paddle 2 Button’ as fire button 2, the Paddle 2 Button itself doesn’t actually respond. I used the configuration described in the link in the first post. How can I separate the inputs for the two paddle buttons?

Thanks to everyone, and have a good day.

iCode - paddle configuration on Atari 7800 - Fire1 or paddle button - missing in action

boanergos — Thu, 17 Sep 2026 22:30:27 +0000

I have an iCode Duo Ultimate H1 Universal USB Adapter. As soon as I got it, I followed the setup instructions (though I can’t quite remember whether they were in a video or the documentation) and managed to configure two paddles perfectly on an Atari 7800 for Warlords. At some point, I made some changes – probably the wrong ones – and had to redo the setup.
Here’s the link to the document:
https://www.icode.com/how-to-set-up-4-player-paddles-on-mister-fpga-with-the-icode-duo-ultimate/

I’m about to go through the configuration process again as instructed. Everything’s going well; I skip ‘fire1’ and click on ‘fire2’ as the second button. When I get to ‘Paddle button’, I click the fire button on the first paddle, but it doesn’t respond to commands. I’ve tried switching off, switching back on, saving… you name it. Can anyone explain why the paddle button isn’t being assigned, even though I’ve left it unassigned as per the instructions?

Kind regards.

RE: Power connection on Digital Dual-RAM MiSTer FPGA

Connect the single barrel side of the y adapter to your power adapter. The 2 wired side of the y adapter connect to your Mister (one the middle barrel connection, and the other the USB power port below it)

Power connection on Digital Dual-RAM MiSTer FPGA

I just received the fully built Digital Dual-RAM MiSTer. The power connection on my unit doesn't seem to match the included documentation.

The documentation reads a Y-splitter with two male barrel plugs, one for the DE10-Nano and one for the USB hub. However, the Y-splitter supplied with mine has one male barrel plug and one USB plug.

Also, the ports on my case aren't labeled, and the picture in the documentation appears to show a different case/configuration from the unit I received.

Could you please clarify exactly how the supplied Y-splitter should be connected to this version of the MiSTer? I don't want to risk powering the wrong port.

Thanks!

Ps. There's a USB dongle in one of the 6 USB ports on the side, what's that?
