@natemac make sure emulation station is closed before you make edits.

@AlexMurphy that 2nd link is exactly what I was looking for. The first dosent exist for me for some reason. Thanks!!!

@herb_fargus theres worse things going on in the world opposed to copyright infringement lets be honest here :)

Thank you for the help my friend. I did it. All works fine now.

@markyh444 I did your instructions and deleted the downloaded images and xml games list file on samba shares because I was tired of looking at the scrapes art on emulation station.

Only problem is that I rebooted emulation station and there is no recreated xml file, I checked on samba shares too. Not sure why there’s no new xml...

Concerning number of ROMS:
my list includes 4714, so if ClrMamePro states 4720 it should be easy to find the 6 missing ones by comparing. Or maybe I just missed some of the BIOS files to be removed (actual game roms should be 4705 according to @markwkidd ).

I'm back again trying to scrape MAME. Using the options available in the latest version of USX I'm still getting a simple gamelist without all the extra bits. Has the database been updated any with the information on clones/etc yet? I know you said this was in the works before, but this thread is 8 months old and I thought maybe SOME progress has been made...

@tonberryhunter Yes you can edit game info and add cover art. You do have to wait for edits to be approved though

i saw someone copy a .cue file and change the name. I have not be able to do the same and been having the same issue with my psx. I need to find a .cue file first to give it a shot.

@screech

Hi, cery strange issue..
I can't scrape anymore samsho4.
Every time i try to scrape it the program crash.
I scraped with mame, neo geo, but always the same result.
I'm on newer version of uxs..
This appen with only this rom, for now..

@Pyjamarama
Sadly the scraper currently does not support Amiga:

An auto-scraper for EmulationStation written in Go using hashes. This currently works with NES, SNES, N64, GB, GBC, GBA, MD, SMS, 32X, GG, PCE, A2600, LNX, MAME/FBA(see below), Dreamcast(bin/gdi), PSX(bin/cue), ScummVM, SegaCD ROMs.

I would love to use it for Amiga games also :(

@vbs I'd recommend you to take a look here:
https://forum.recalbox.com/topic/4690/soft-universal-xml-scraper-v2

Can you post commands used to mount external USB HDD. I'm running roms off usb and made folder structure on USB. /home/pi/RetroPie/roms/atari2600/images but retropie doesn't use them. So I assume it must be that I didn't mount it.

thanks guys. the sd card isnt full as it says there's like 29 gig free on it. ive tried the inbuilt scraper and the sselph one and still get errors. i thought the images wrre stored in the roms folder now in a folder called images so therefore stored on my nas? I could be wrong though.

@3lric Awesome, thank you for the help. I will go through this and report back.

Thank you for writing back @meleu I think my "method" is somewhere inbetween. The fact is my non-merged full 0.37b5 romset (2241 roms) matches perfectly the 0.37b5 snaps (2241 snaps, a lot of work saved!) so what I do basically is:
1.- add
screenshot_directory = "/home/pi/RetroPie/roms/mame-mame4all/images/"
to
/opt/retropie/configs/mame-mame4all/retroarch.cfg
2.- move roms to Retropie/roms/mame-mame4all
2.- move snaps to Retropie/roms/mame-mame4all/images
3.- run
/opt/retropie/supplementary/scraper/scraper -add_not_found=true -append=true -download_images=false -image_dir="images" -image_path="images" -image_suffix="" -img_format="png" -img_workers=0 -no_thumb=true -thumb_only=false -thumb_suffix="" -use_ss=true -use_gdb=true -use_ovgdb=true -workers=4

Then gameslist.xml is created. I think those steps might be useful to users who already have a preference for snapshot packages.

However, I wonder what would be the best approach in the following scenario where there it no a rom <--> snap match:

1.- add
screenshot_directory = "/home/pi/RetroPie/roms/snes/images/"
to
/opt/retropie/configs/snes/retroarch.cfg
Move all 3438 No Intro SNES roms (Nintendo - Super Nintendo Entertainment System (20161130-222348_CM).dat) to
Retropie/roms/snes
Move all 3352 .png snapshots (No-Intro 20061119 Super Nintendo Entertainment System Screenshots.7z) to
Retropie/roms/snes/images

One more problem, snapshots name do not match rom names but it is relatively easy to sort it out.
Eg. Actraiser (U).png versus ActRaiser (USA).zip
So I have run a number or find and replace to swap U for USA, J for Japan and so on. Once .png files match their counterparts in the roms folder, the same scraper command is run to generate gamelist.xml
In any case, it is clear that there are less snapshots than rom files so there will be roms without snap. Any ideas on how to find out (list) what are those roms?

PS. I am going to have a good look at that link. Thank you for it.
