@The16BitGuy Please post the full error message and the step in the installation where you get it. What version of Ubuntu are you using ?

@ivooc
Yeah I meant threaded video. I've had the same RetroPie build from version 4.4, its hard to remember all the changes and configurations I've made. I'll try to share once I think of them.
Do you have a fan installed? The temp_soft_limit is 60 by default and will throttle the cpu to 1.2ghz
I increased the soft_limit to 70 and it barely reaches 63 during emulation.

Have you updated retroarch, raspbian, and your cores, since you installed the image?
the firmware, I should search to find out for sure, I think it is updated when you go to retropie config >> configure >> raspbian >> update raspbian(next to install pixel desktop)
It could be a psx_bios, some have higher compatibility, I have quite a few in my folder actually, but I think scph_101 is the highest compatibility and it will be chosen over the others, not to be confused with scph_1001.

As I say that Gran Turismo refuses to work.
I don't know why, but I did update the core since I last played it.

Please can you have the crc32 for level2.rom of the trs-80?
In the doc file the link for download is old. Error 404.
If can give me all crc32 for all bios?
Thank you very much.
Sorry for my bad english.

@mitu alright, you can delete this thread, I'm not really sure how. Appreciate the responses

@Efriim It is possible if you feed it some outlandish timings. I am not saying the ones you have posted will do that, they may well work OK, but not knowing the source and what they were intended for it's hard to say. I'm talking about the hdmi_timings ones, these can be dangerous. The config.txt is good, but I would skip the ones from your post starting with hdmi_cvt.

I'm bit busy now but will post my confirmed-working settings (for a CRT TV though) later. In any case OP should try the arcade forge image first, even if just to copy the configs from it to the official Retropie.

EDIT: my old config.tx. You can also try the "AF" and "mohl" settings (just make sure to remove #AF for example)

gpu_mem_256=128 gpu_mem_512=256 gpu_mem_1024=256 disable_overscan=1 disable_audio_dither=1 dtparam=audio=on dtoverlay=vga666 enable_dpi_lcd=1 display_default_lcd=1 dpi_group=2 dpi_mode=87 hdmi_timings=320 1 15 20 49 240 1 6 8 10 0 0 0 60 0 6400000 1 #c64hdmi_timings=336 1 10 18 46 288 1 5 6 6 0 0 0 50 0 6400000 1 #AF hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1 #mohl hdmi_timings=320 1 10 20 54 240 1 6 8 10 0 0 0 60 0 6400000 1

This should give you a stable picture, I have used these settings on many CRT TV sets, they should work on a monitor too I think (or at least won't damage it).
problem is, this will only work for few emus in 1:1 scale, since they often used different resolutions. To handle this you need to use the high-res trick (read the thread I linked to)

For that you need to change the runcommand and then also adjust the settings in retroarch.cfg (custome aspect ratio and resolutions, or use integer ON/Off option). Unfortunately I'm not near my SCART TV sets and can't remember all these settings exactly so can't help you here. You either use the Arcade Forge image, figure it out from the resources here or post on reddit in /r crtgaming sub.

My runcommand-onstart

fbset -depth 8 && fbset -depth 16 -xres 1920 -yres 240

My runcommand-onend

fbset -depth 8 && fbset -depth 16 -xres 320 -yres 240

You don't seem to run RetroPie, so why post here in the forums ? You can find the list of resolutions you can add in config.txt here.

@fomt No, keep the other steps, just don't run the passwd -d <yourusername> step.

@Littlezero .srm and .state files are not ROMs, as you have discovered.

@marcoabm there is a way to do this so that someone has to press the back button (usually coded as B) to get out of the favorites list. I BELIEVE though I am not in front of my pi right now that if while in emulation station you hit the start key to get to the emulation station menu you have to change two options (btw I have this set up on my bartop this way for the reason you mention). First there is an option for start on system or something similar and you can choose “favorites”. This way when the pi boot it will go right to
Favorites. Then there is another option. It might be called quick system select or quick carousel or something. You can disable that and now someone can not switch systems by moving left and right they have to press the button to physically back out of the favorites menu and back to the top menu. I will try to find the exact name of the option later if you can’t find it.

EDIT: Ah! I found it online. It is in the emulation station menu as UI options, then “quick system select” you want to disable that. Also, if you want to go super extreme and don’t want to leave it as just difficult to go to the other systems but rather make it absolutely impossible to do that; you do the foregoing two steps and then also edit the configuration file that is related to the actual control buttons for emulation station and remove the back button. I am not a big fan of that personally because I still like to be able to back out sometimes but if you really want to do that I have done something similar (switched the button used for menu and back in emulation station) so could walk you through it.

@mitu Very true! Perhaps he's missed his nap and has gotten a little fussy.

@mitu
Dont Know :O)
Havent try it yet. But i Thought to install Atari ST, was maybe the same way to install Amiga.

@RetroJoe This is not a ROM sharing site, the rules are there so people understand that. You seem to have not read them - https://retropie.org.uk/forum/topic/2/forum-rules.

Freeware and demo image

That doesn't give re-distribution rights automatically. There's a topic dedicated to how to legally obtain games/ROMs, you may post there - respecting the forum rules - links to games you think are freeware/demo:

https://retropie.org.uk/forum/topic/10918/

Well, starting off the ps3driver is pretty good and if you want the default Hotkey(PS_BTN)+Start then this won't be a problem;

However if you want to assign custom hotkeys to retroarch, if you do this with the controller plugged in, it will assign the button number manually and these will differ than if you connect wirelessly with the ps3 controller. You can always press start on a retroarch option to reset it to its default(auto) value, where it will find the start and hotkey buttons automatically and not reference an arbitrary button number from its disconnected duality.

There is a solution to this without transcribing the root configurations to bend the systemdaemons to your will.

In the RetroPie management package drivers there is an alternative, the sixaxis helper driver. Installing this will uninstall the ps3controller driver and replace it. The arbitrated button numbers for wireless and connected will be as one and you can configure input mappings peacefully.

try turning either auido sync or hard gpu sync on in the retroarch settings

I m sorry to say ,but you need to go through a fresh install of retropie. this happened with me and i tried all different kind of ways but at the end i had to take the trouble.
All the best.

Sorted, finally found this thread which shows the exact way to wire them.

@George-Spiggott said in Script to Mirror SD Card to USB Stick?:

Currently RetroPie automatically copies files (roms and configs) from a USB stick to the Pi. Is it possible to disable this process so that it happens on command rather than automatically?

Yes, disable the usbmount service and the synchronization will not happen automatically.

Also is it possible to reverse the process so that the USB stick can be used to mirror the contents of the Pi, or at least select folders from it, either automatically or ideally on command?

Yes, it's possible, but there's no provision in the RetroPie scripts for this kind of scenario.

When you want to keep your ROMs on an external drive, you create a retropie-mount folder on it and RetroPie would sync the ROMs from the SDCard to the disc, then it will mount the disc so you can use it.

If dont' want to use the external disc for the ROMs, but just synch to it, then you'll have to create a script to do it. Both synchronization methods (USB to card and vice-versa) use the rsync command, you can easily create 2 scripts to do this synchronization and add them under the retropiemenu system so you can call them directly from Emulationstation.

@sohailoo Thanks for the info.

For metadata, you will need to install Selph's scraper from the setup script. Once done, then exit ES and run the following command from the terminal or a SSH session:

cd RetroPie/roms/psx /opt/retropie/supplementary/scraper/scraper -img_format=png -image_dir="./boxart" -image_path="./boxart" -download_images=false -image_suffix="" -marquee_dir="./wheel" -marquee_path="./wheel" -download_marquees=false -marquee_suffix="" -video_dir="./snap" -video_path="./snap" -download_videos=false -video_suffix=""

The above is an example for creating a gamelist XML for Playstation (PSX). For the other systems, the working directory needs to be changed with a command such as cd ../snes/ before running the scraper.

For arcade roms, remember to include the -mame parameter in the scraper command.

Glad that you got it fixed, but please, in the future:

Add all of the information that is requested in the link @mitu gave you. It helps potential helpers to help you. You only added part of it in your first post. edit: It's better to post a new post to add the information, so that anyone following this thread will be noticed automatically. New posts trigger forum notifications, editing posts does not. (I only noticed the added information after I wrote the first version of my reply.) If you got it fixed by yourself, it would be nice to tell us how exactly you fixed it, so that others with the same problem can find a possible solution here. Edit your first post and add [Solved] before the title, so that it's clear that this thread is solved.

Thanks, have fun with Retropie.
