@barbudreadmon You're right. I have found that it was saving the NVRAM file by default. And I found it in the folder for Mame 2010. I have also confirmed that if I back that up and put it into that folder at first boot, it does restore the game back to the settings I preconfigured. This is what I needed thanks!

Searching the internet I found that these errors are quite common and harmless. Since its giving me 0 issues ill just ignore it for now.

@EctoOne said in [Solved] Map SPACE to be useable in dialog menus?:

@sleve_mcdichael I don't know what happened, but now they do work as intended.

(...)

Wel, guess that's solved.

Hey, it happens to the best of us.

@Threat_Craft-0 generally they are stored in the rom folder next to the game, as a .srm file.

@sleve_mcdichael...oh wow! I was a little perplexed after reading your suggestion, but ultimately found the solution! I went into Retroarch and changed the port 1 binds to Xbox One Controller and even changed the video aspect to 19:12...and proceeded to save as a core override. Now when I start the N64 games, my Xbox Controller is the primary controller, and my joysticks are NOT! SWEET!! Thank you!

If you are sure the PSU can deliver 5.1V constantly or more (but not higher than 5.5V) under load then most likely the USB cable may be another source for the undervoltage. Search for "micro usb 24awg 2c". The AWG24 wire gauge allows up to two ampere. (cf. here). And pick the shortest you can get. It may fix the issue.

However, from theory this may still not enough for an RPI3 (rated 2.5A).
You may try this, but do it on your own risk: Power the Rpi3 via GPIO headers. This bypasses the voltage regulator of the microusb port, so only use a PSU which has a stabilized output. Caution: Any mistake in wiring will fry your Rpi.

Get or make two DuPont wires with female endings, either AWG24 or AWG22 Cut them apart, thus you have two for 5V and two for GND at the GPIO header Properly attach the DuPont wires to the PSU, note the polarity Attach the female endings to the respective GPIO headers (use 2x 5V and 2x Ground) (https://pinout.xyz/#), again note the polarity Make sure the wires do not losen during gameplay

I have update a system from RetroPie 4.7.1 to 4.8 without issue. Better configure the system after the update to 4.8.

Use the screen configuration utility and make the 2nd HDMI port the primary screen.
Note that RetroPie is not supported on a desktop environment or on TwisterOS.

@EctoOne Yeah, I've seen that thread too. It's saying that the dock is using a unique way of wiring up the HDMI port, and that other docks besides the one it came with don't seem to work because they don't support the oddball standard RetroFlag chose. The port does work as a regular USB-C port though.

@MSP430 so far none of the systems you mentioned go over the resolution of your display. The PlayStation has a few games that go over, like tekken 3, or silent hill in the menus, but I’m sure it’ll look fine on a lower resolution display, if not a tad fuzzy and text might be harder to read in the higher resolutions.
Just know that PlayStation and especially n64 will be iffy on a pi zero. Not sure about a zero 2 for PlayStation, but n64 on a pi4 has many performance issues which is much more powerful than any zero.

Seems similar to https://retropie.org.uk/forum/topic/32891/ and (the recent) https://retropie.org.uk/forum/topic/32997/. Try modifying the .cfg file for your controller as explained in the 1st topic and start a game again.

@TKoller said in .data folders:

can anyone explain what these folders are and why they are only on my friends pi?

Maybe you can ask your friend, since they're the one that set it up. RetroPie doesn't provide any ROMs, so they must have been added after the installation.
If I had to guess, they've used the .data folders to hide certain files from being displayed in the gamelist - a common method when you have a multi-disk game and you want to show just a single entry for the game (i.e. create a .m3u file pointing to the individual disc files placed in the .data folder).

@Darksavior said in Edit core keymap to only affect NeoGeo games?:

@WeirdH Not sure if it's the answer you want, but I put my neogeo games in the neogeo folder so I can set up my buttons specifically for it.

That would be the correct answer or at the very least the only method i know to remap several games having the same layout at once.

Please add some more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Post your /boot/config.txt and /boot/cmdline.txt.

When you post an image, if it's wider than 1520px, the forum automatically generates a preview image for the post that's smaller, providing a link to the original image.

What I think happened is a bug (?) in the forum job that looks for 'orphaned' uploads (uploaded files from removed or cancelled posts) and deletes them.The job erroneously removed the preview images and thus the missing image in the posts (clicking on the link would still show you the original image).

@BuZz restored the preview images, for now I've disabled the 'cleanup' job until the issue is solved.
