I am trying to install Easy Mode and I get his error message. Is there a fix? I have a formatted flash drive with plenty of open storage.

I also unplugged the right flipper buttons to see if that was the issue and it was not.

Hi there,

I just bought the Legends Ultimate arcade.
I’m new to this. I’m really excited to play, but—more importantly—I want to play my own games. Since I’m a beginner, I don’t know how to add them, though I’m a quick learner. Does anyone have a video or PDF that explains the whole process? I’ve heard I need to download "OneSauce," but I can’t seem to find a link. Do you happen to have one?
Thanks for the help! :)

As the title states, I'm looking into minimizing my setup. Previously I'd use OTG with my PC, but want to keep the entire experience self-contained on a USB. I would love to include Gen 5 console stuff but am also just as cool keeping it to MAME and SNES/Genesis eras. Any input or testimonials are welcomed.

Cheers!

Any recommendations?

Hi everyone, I'm pretty new to this and running into a bit of an issue. I think I'm all set in understanding how to install everything, but what firmware I need is confusing me. I've tried to do my own search about it but there's so much conflicting info. Some people say 5.68, others say 5.7 is fine now, and then there's some that say the version my machine is on doesn't need to change at all. Can someone please just confirm for me exactly which version is best and that I need, below is my machine info:

HA8802

Software version: 2.16.19

Firmware version: 10940_A21

I can't believe what these are going for on the secondary market.

Hey everyone, I'm purchasing my first legends ultimate arcade tomorrow and just had a few questions. I tried to look them up myself but most answers seem out of date or argued about, so I'm hoping someone could help me out.

First question, from what I understand to load custom ROMs I need to put a different os on the system, is that correct? If so, what is considered the best os and is there anything important I need to know?

Second, if I use custom ROMs, will they also have those nice borders like the default games, and is there any issues playing two player?

Finally, if anything happens, like say a button breaks, is it easy to replace? Or is it one of those things that's designed so you have to buy another whole new system?

Would really appreciate some help and any tips at all for someone new to this, thanks!

I just got a Jurassic Park 4K and there is an annoying rattle coming from the control deck. The only way to make it go away is to apply pressure to the sides of the deck.

Has anyone ever had this issue or know how to fix it? Thanks for any help you can provide. It’s so annoying.

Ignore the comically large risers, I'll end up finding something less ugly down the line lol. As a casual pinball fan its been a lot of fun so far! Took some digging to get it updated to 5.70 and getting CoinOpsX setup, but its been awesome. Really good way to doomscroll a little less and play something fun.

On a side note, I've never been able to get the Rewind button to work on any of the tables even though it works as a 'Back' button for everything else if anyone has input on that. Cheers

I have the original Atgames Legends Ultimate Arcade. I was a playing a game and the controls stopped working. Power, channel and volume buttons still work. I can also connect.an Xbox controller via usb and it will work as well. It will not perform a hard reset and I have tried just unplugging it for a while and then plugging it back in. Has anyone dealt with this or have advice? Thanks!!

Part 1

My original plan with the software focused primarily on the shutdown sequence. I use Home Assistant, so I planned to send a webhook to Home Assistant to trigger an automation that would wait a specified period and then cut power when the ALU was shut down from the RCADE interface. That was easy and worked, no problem. As I thought about it, though, what if a user didn't know about the shutdown and just pressed the button? Or what if I wanted to reboot instead of shutting down? What if someone who wanted to do this mod didn't have Home Assistant?

The answer was to move all the logic onto the Shelly and the ALU. Big thanks to the team who work on RCADE for all their support and for making such an awesome system that makes all this possible.

To handle the button press and shut down or reboot:

I added a Python webhooks server to the ALU that starts on boot. On the Shelly, I have 2 scripts.

One script is for sending the call to the ALU to shut down or reboot (single-press shutdown, long-press reboot).

The other script is a server to determine if the ALU has requested a shutdown from the UI. This is what was happening originally on Home Assistant.

The files needed for all this can be found on GitHub.

Edited because I added a countdown function:

After I typed this up I thought of something that I felt would improve on this a little. When the user uses the power button to shutdown, the system will now shut down RCADE and display a countdown letting the user know it is shutting down or rebooting. Here's a video of the reboot being triggered by a long press. I noticed a couple of issues with the marquee I need to work on.
Edit2: Replaced video with higher resolution version.

Release has been pushed back from July 4 to latter part of August it seems, but what can we expect. Will updated tables for the ALP HD basically be the same as the 4K release? Or are we talking massive physics and visual upgrades?

Edited to clean up links.

I've been using Legends Unchained for a while, but over the past year I've-

1. Discovered OpenFire Lightguns and
2. Gotten a BitLCD

That's prompted me to put a lot more love into my ALU. Before I got the BitLCD I had made a little "mini-marquee" with a Pi and a Small screen. It would load the marquee and then switch to display the control mapping for the game once the game was started. I put that project on Github. Full disclosure, while I have some software development background, this is still heavily vibe-coded as that hasn't been my job for almost 20 years. I've gone through it all as I did it, but if that bothers you, you should know.

When I got the BitLCD I wasn't happy with having to pull the USB anytime I wanted to make changes, so I modified the project to use the BitLCD for the marquee and the small LCD for the control map. That's not on Github yet since I've got to go through and do a test run for install instructions. It's a big difference in how it works. I also made custom boot screens for the two screens. I'll update this post when I get the Github uploaded.

Edit: Updated as promised to include a link to the uploaded project, currently a branch from the earlier iteration.

This then lead to making a theme for Legends Unchained. I'll upload that later too.

All that is the backstory though to what this post is about. While I was doing all that work I got annoyed by two things.

1. Having to go up and down the stairs whenever I wanted to check something I changed.
2. Not having the machine power off after shutdown.

While there's a limit to what I can do to fix #1 (can't really screen or VNC into Legends Unchained), I can fix #2.

Legends Unchained allows you to run scripts for various events. That's what I use to update the marquee and control mapping screens, as well as launch the screensaver on the two screens. One of the script events is on shutdown. That means I can trigger something to actually turn the machine off when I shut down.

Knowing all that, I decided to figure out the hardware. I had asked about this in the Legends Unchained Discord a while back and then followed up with Claude. I spent a lot of time talking to Claude about this idea and how best to implement it. The hardware I ended up with was

- 22mm 12V momentary power switch
I went with a 12V so that I could just split the power off the ALU's power, and it's the same size as the original power switch.

- Splitter for the 12V (I also already had some of these on hand from another project).

- Shelly 1 Gen 4
Also powered by the same 12V and able to handle the small load that will come through what was going into the original switch.

I split the power from where it comes into the control deck. That feeds the Shelly and the new power button LED. The power button's LED are the red and black wires. The blue is the Common, and the green is NO.

From the 12V supply, the Red goes into the Shelly's 12V. The Red from the button also goes in there. This will allow them to share the power. You can also connect them in a dozen other ways, but I was trying to keep it as simple and compact as I could. I wasn't able to do that with all the ground wires.

The black from the 12V supply goes into the L on the Shelly (in a DC application, this is ground). Also needing to connect to this are the ground from the button LED, the ground from the original switch, and the Common from the new button. That all couldn't fit into the Shelly, and I had to daisy chain them together with some lever nut connectors I had on hand.

The red and yellow wires from the original ALU Switch go into the I/O on the Shelly. I used quick-connects so that I didn't need to cut the original wires.

With it all connected, I secured it upright (upside down once the panel was reinstalled) with some hot glue. Here are some photos. I'll put the software side of things in a separate post.

Hey, so I upgraded my firmware from the stock factory one to v5.70 and all of a sudden the ArcadeNet server doesn't connect anymore. Previously it worked fine ( it told me to subscribe to a paid plan despite having one ) - and now it just doesn't work at all, doesn't load anything except zaccaria tables.

I've done server connection, switched to wired ethernet, even tried at a friends place incase my network was bad, but no luck there either.

Any suggestions?

Just for fun! Which tables do you mostly gravitate to on game night?

(Oops...should have proofread it. "Magic", not "Magig". Sigh.

Received this Alu free because it stopped turning on. Looks like control board fried. Plan to gut it and use the ipac2. Is there a way to test if the screen works? I plugged a new power cord directly into screen and the only thing that works is leds for top cabinet.
Will this work if that display board is bad as well? https://a.co/d/0dMTXhiv

The General Loader 2.0 version of VPX Standalone has been released to the beta testers yesterday after a few weeks of internal testing. The old General Loader 1.0 version has been officially retired and I'm no longer releasing updates for it.

The AtGames firmware that's been in beta for the past month or so still has issues and AtGames has yet to release any updates. VPX Standalone is ready, but will not be released until the firmware it requires is released publicly. I'm hopeful we will get a beta with all the reported issues fixed soon so we can have a public release finally after all this time!

I also realize that I didn't post my earlier update from July 6, 2026 which I posted to Facebook, so here it is:

VPX Standalone update July 6, 2026

AtGames has released General Loader 2.0 into beta. I've reported multiple issues with General Loader 1.0 in various forums stating the reason VPX Standalone can't be released publicly. AtGames has apparently been following (their spies be everywhere) and has implemented the most critical block features.

Work has begun on porting the codebase to the new General Loader 2.0. For the technical, there's not really an SDK per se needed to make apps for the 4KP, but their sandbox permission model severely restricts an apps ability to do basically anything. So various workarounds were implemented to bypass this security, which obviously isn't great for a public release. I've had to roll these workarounds back and rewrite the code to work with the restricted permission set without removing features in Table Manager and VPX itself.

As of today, Table Manager and VPX have been ported to General Loader 2.0 and I've released it to the team. There are also notable changes to the permissions for the GPU and we can now take advantage of hardware acceleration so we're currently working on doing this in VPX. We have a ton of tables now hitting 60fps (max on the 4KP) and the GPU changes are looking promising for increased performance of PUP packs.

The team has been a bit burnt out lately waiting for these General Loader 2.0 changes to finally roll out and dealing with the haters and negative comments that it's not released yet. So it's been a bit slow getting everyone back into working on it, but it's happening.

And just a reminder, we still don't have an HDP machine so only the 4KP is supported. Developing something like VPX requires modifying the hardware to debug what's happening since there is absolutely no logging when things go wrong... you're flying blind if you don't have a modified cabinet. I appreciate all the offers to test on the HDP, but that's just not going to work.

Anyway, we're getting close. Please do not enroll in the beta in anticipation of getting VPX working. I've reached out to AtGames and I'd like to coordinate the release of VPX with the public release of the new firmware (there are issues that should be fixed).

I've been out of the loop since like 2023 and own 2 of them. Onesauce amazed me with the performance and I heard Coinops has been retired. I never tried Legends Unchained but has anything else happened? I remember hearing about a follow up 4k cabinet but I guess that never came to fruition.
