@valabrax said in Which files/directories should I restore after doing a fresh image install?:

Looking at the backup methods on https://retropie.org.uk/docs/Updating-RetroPie/ I think the best one for me in this situation is to backup the bios, configs, and roms directories via the samba shares. However, assuming the update works perfectly, which of these directories should I copy back over to preserve my roms, save states/files, and configurations (like controller configs and core-level configs). I'm assuming just the roms and configs directory and that I should not copy bios back over to the new image, but I wanted to check and be sure.

as the docs says, you'll want to backup all 3 https://retropie.org.uk/docs/Updating-RetroPie/#backup-option-2

By installing from source and now doing a new image install, am I nuking my micro-sd card with writes? I have no idea how many writes an install from source does, but it took hours to finish.

it's not ideal but during development i do many days worth of rebuilds and my SD cards tend to last years before crapping out.

For my RPI 4B+, I bought this one - https://www.amazon.ca/gp/product/B07W6T25Y4/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1.

It has an on/off switch - which the Canakit adapter didn't have, it is manufactured by a reliable (name brand) company and has great user reviews.
Since I have used it, I never have the yellow lightening bolt (low voltage warning) show up in Raspberry Pi OS - a problem I was plagued with in my Raspberry Pi 3B+ setup and generic adapter.

@oleguer The CEA video modes you're referring to are set via tvservice, which doesn't work correctly on the Pi4 so those set of video modes are not available. The runcommand launch menu shows the resolutions that your TV reports it supports - that's what is offered for the video mode change.

You can set still a custom resolution via config.txt (see https://www.raspberrypi.org/documentation/configuration/hdmi-config.md) if you wish to use a video mode not reported by your TV.

@buzz Yup, I stand corrected. I think it is the NOOB image that it was installed on by default. or maybe something else I downloaded.

@mitu I didn't, I created the GAMELIST.XML from scratch.

Hi all, sorry for dragging up an old thread. Has anyone got this to work on the latest Retropie image (4.7.1)? I had it installed on an old 4.4 image working absolutely fine, thought I would update to latest image 4.7.1 followed all the same steps (actually copied what was written in the old image that worked) in relation to detecting hdmi. But I can’t get it to work in 4.7.1, it always defaults into hdmi and cannot get itself back into lcd when you don’t have an hdmi cable installed. I often see ‘Unk-Comp-Dev’ in the text when booting rather than ‘[E] No Device Present]. Wondering if the updated Retropie version somehow recognizes the LCD screen differently which is preventing this script from working? It seems to always boot into hdmi like it always thinks something is plugged in when it’s not.

Any help to get it working would be much appreciated!

Thanks!

Ok found a solution in another thread no longer need a script to do what I need just a simple addition to the config.txt file, all sorted! Thanks!

@heaven76 said in Very slow loading times on lr-flycast:

After that i tried using the quirks workaround as suggested by @mitu

What filesystem are you using on your SSD? ext4 or NTFS?
NTFS is no good.

@mitu so i was able to get it working by importing the gpg key.

all is well!!

@sleve_mcdichael xrandr only works when X is running, so the setting won't persist in a pure commandline/framebuffer environment, like retropie on the pi. as soon as you exit the desktop, everything is back to how it was, as far as i'm aware.

you can attempt to run retropie within X, of course, but that's not a supported configuration. however it's probably the path of least resistance for non-standard display setups (rotated, CRT, etc), as xrandr is so powerful...

@mitu when i run emulationstation i get this error ;no available video device' ' error initializing sdl!'

@mitu I'm having this same issue.

I've ran sudo ufw disable to disable my linux firewall.

I'm thinking that the issue is with my OPNSENSE router.

Which ports should I forward to my retropie server?

@mitu Quick update: lr-pcsx-rearmed and lr-parallel-n64 worked.

@theretroprince said in Using Analog Sticks for 8-Bit Stuff?:

@alphabetapie You will not want to enable this for systems where the analog and digital controls are independent. For example, on PSP and N64 the control pad and analog joysticks on the actual systems are not interchangeable. (Analog joystick controls are separate from digital joystick controls and provide different inputs)

Enabling this option for these types of controllers/systems would cause dual input problems.

Good point.

@alphabetapie said in Is There a Favorites Glitch in Kiosk Mode?:

but would love if someone could mention to them that kiosk mode with favorites disable is a great idea and should be reimplemented in the future.

Agree. Perhaps a flag that could be set while in Full mode, which would toggle Favorites functionality in Kiosk? So it could still be available for those who want it, but could be disabled if you want to leave it with the knuckleheads for an afternoon.

I'll be glad to suggest it or put a request in, if you can provide a link to where I can do so.

Also, anyone have any ideas on if the Y button icon in the help menu at the bottom of the screen is editable (and if so, where)?

@jamrom2 said in Why does my 8bitdo and PS3 controllers randomly move?:

so if a ghost input is +.02 volts... and an actual press gives + 1.2 volts... you would set the null to ignore anything under +1.0 volts. Effectively ignoring the ghost input.

It doesn't work like that. There is no method to know how much 'volts' trigger the input, in order to ignore it or not.

Hi guys. I’m new to the forum and stumbled across this post. I know it’s old but I’ve got this exact same problem.

I have the nes30 pro. The lag is unplayable. Sometimes it works fine then sometimes it just does it’s own thing and wanders off. I’m using an 8bitdo Bluetooth dongle since the built in Bluetooth on the pi4 was impossible to get working with this... and also I have a nes30 controller too which was totally impossible to sync up with Bluetooth.

The nes30 controller however works fantastic with the 8bitdo dongle... but the nes30pro just does not work good at all.

Both controllers have had the firmware updated also.

I’m stumped how the nes30 works great yet the nes30pro is really bad. I’ve disabled the onboard Bluetooth on the pi4 in case it was interference of some sort?

Anyone had this problem and got around it? These controllers aren’t cheap either which is more annoying as I’d like I to work.

Thanks.
