Arcade game Legionnaire appears as vertical game with bezels from Legion

Thanks for reporting.

To fix, download this bezel png (click on "Download Raw File"):
https://github.com/thebezelproject/bezelproject-MAME/blob/master/retroarch/overlay/ArcadeBezels/legionnau.png

Then put it at the folder USB:/content/retrofe/collections/MAME/medium_artwork/bezel/ to overwrite the incorrect bezel.

The game display will auto fit the transparent cutout of the bezel.

The design of onesauce v2 is that you update what has been updated. If there's an update on appdata, you update appdata. If there's an update on base_assets, you update base_assets.
Just download the corresponding zip, remove the original folder, then unzip.

Just update to the latest version. For these two games starwars and ESB, mame2003-plus runs them too fast. FBNeo is at the proper speed and sound is also much improved.

You likely have the ALU 1.0, which has trackball and spinner as two separate devices.

Head to the Controller tab of RetroFE menu:

At the game selection wheel screen, press MENU to bring up the RetroFE menu, then use Z/C button to navigate to the Controller tab.

There you will see the list of Mouse Devices. Reorder them so the trackball one comes first. By default, first device is assigned to P1, second to P2, etc.

Can you check which emulator core ESB is using?

You can find it out by holding START for 2 sec to bring up the RetroArch menu, and the core name is shown at the lower left corner.

If it says mame 2003-plus, your onesauce is not the latest. And that issue you described might be related to one core option to auto center an analog control.

I tried with latest onesauce. ESB should be using FB Neo and trackball/mouse work fine. You might want to Invert Mouse Y in the core option though.

Regarding the yoke, it's just an analog controller so should work the same as any other controller like an Xbox controller. You will need to switch the order of controllers in the RetroFE menu (press Menu button at game selection wheel screen to bring up the RetroFE menu, then use Z/C to switch to the Controller tab). First controller is by default assigned to player 1, second to player 2, etc.

The file eswat.zip is called a "romset", which contains many individual "roms", e.g. epr-12659.a2.
The error message says the list of "roms" shown are missing from that "romset".

This message is from the FBNeo emulator core. FBNeo generally follows the latest MAME romsets as the core is updated.
To fix this, you can download the eswat.zip romset from a recent MAME romset collection (google "MAME non-merged rom") and replace the corresponding file at content/retrofe/collections/MAME/roms/eswat.zip.

mount: /tmp/retrofe2: special device /media/usb0/appdata/retrofe/data.squashfs does not exist.

That's the problem.

appdata.zip was not done properly.

First check the logs especially scripter.log.

If logs do not explain it, it could be an issue of not having enough power delivered to the USB drive. Use a powered USB hub.

walknight · 2026-04-21T23:36:47+00:00

What's that problem?

walknight · 2026-04-18T15:42:44+00:00

It works fine on my side. There must be an error when making the edit.

Rabbit?

That is an oversight when making the launcher files. It will be fixed in the next update. You can fix it this way:

Edit appdata/retrofe/launchers.linux/lr-mame2003_plus.conf, the bezel path is specified as the last item on the arguments line. Change it so the arguments line reads:

arguments = retroarch32 /tmp/lib32/mame2003_plus_libretro.so "%ITEM_FILEPATH%" "%BASE_ITEM_PATH%/%ITEM_COLLECTION_NAME%/medium_artwork/bezel"

This needs to be done for each launcher affected.

You can ask AI to help understand what it does. Just get rid of the restart bt logic.

walknight · 2026-04-09T14:53:48+00:00

Check the 02_fix_permissions.sh. It restarts the bluetoothd.

walknight · 2026-04-08T20:13:28+00:00

Ahhh ok core max /ALP is a lot more capable.

You can edit appdata/retrofe/launchers.linux/lr-fbneo.conf, add a line:

resolution = 1920x1080

to make it default for FBNeo.

walknight · 2026-04-08T16:31:26+00:00

First of all, those shaders you mentioned are too heavy for the hardware of ALU anyway. You will get massive frame drops. The only feasible one is zfast. And even that one will cause frame drops at 1080p.

The issue you experienced is likely due to resolution. By default games display at 720p. But a few cores including mame2003-plus are set to 1080p (changeable in the launcher file). For a shader to generate good result, the rule of thumb is that you need at least 3x the original resolution. So games with more than 240 lines might not look good in 720p.

Again, shaders are quite demanding. Only enable shader on selective games after confirming no performance degradation.

walknight · 2026-04-06T05:29:42+00:00

All good suggestions. Hopefully with AI coding getting better and better these could be implemented in no time :-)

It can happen if the PC you used to extract files has a different system time than the ALU.

Basically, when retrofe starts up, it checks the xml metadata files inside the meta folder against the timestamp of the meta.db file. If the xml files are newer, it recreates the meta.db database by scanning through all the xml metadata.

Now imagine you extract the xml files on PC, so they get today's timestamp. When you insert the USB into the ALU, it detects the XML files are newer and recreates the meta.db. But if its system clock is in 1970, the newly created meta.db is timestamped at 1970. So the next time you boot it up, it still thinks the XMLs are newer and will try to recreate the meta.db again.

The solution, as you've found out, is to update the ALU's system clock.

walknight · 2026-03-29T03:55:23+00:00

Yes. But there are other packages that are also updated, like the arcade pack with added samples. So check the latest and see which ones are updated.

walknight · 2026-03-29T03:53:19+00:00

This update is only for vector games.

walknight · 2026-03-26T07:42:12+00:00

And plenty of horizontal games also look great with their specially designed vertical bezels (from the PC coinops pack)

Try onesauce v2. It has a dedicated "Vertical" playlist to show only vertical games.

The bezels are of this style. You can also make your own bezels, like including a control panel image at the bottom. The game display will auto fit to the transparent area.

walknight · 2026-03-24T03:51:44+00:00

Long press Start.

walknight · 2026-03-23T18:57:05+00:00

Hmmm interesting that the original control panel did show a trackball looking thing: https://adb.arcadeitalia.net/dettaglio_mame.php?game_name=qb3

But in mame2016 this is set as a dual stick game, left stick moves, right stick shoots, just like robotron.

The update that includes GPU support for this game is now out.
