Easy way of renaming Arcade roms?

MikeLang

I want to be able to edit my arcade roms so they have the correct name.

At the moment I'm editing the emulationstation\gamelists\arcade\gamelist.xml

<game>
<path>./supeni.zip</path>
<name>Super Ninja Man</name>
</game>

But the problem is not all the games are listed unless I run them. Is there a way I can generate a complete list of all the arcade roms without having to run each game?

I want to avoid using any scrapers as disk space is at a premium.

@MikeLang What version of Emulationstation are you using ?

If disk space is limited, how about using scraper without the images? I don't know the right options here, but it should be possible. Alternatively download or convert the images to very low quality and jpeg size. Just a suggestion. You would save a lot of work.

The right options could be -max_height height, -max_width width or -thumb_only.

Otherwise, I would look at a typical entry in gamelist.xml and create per automated script a list of all files and then my own gamelist.xml from it. The correct name associated with its filename is also stored in the MAME emulator itself.

The default one that comes with RetroPie v4.4

Recently tried a scraper and it left me with zero memory left, even after I uninstalled the scraper, 150MB completely vanished.

@MikeLang Did you try my suggestion using sselph scraper with the option -thumb_only, which should not download the normal images and only get the very small and low quality thumbnails. It would require only very few space, compared to the normal operation.

My system literally only has about 200MB left, even that will probably be too much. The renaming method I am currently doing keeps the space used at an absolute minimum.

@MikeLang The simplest way may be to remove the gamelist.xml file that you are editing.

If arcade roms haven't been scraped, then EmulationStation will auto-populate arcade roms with their full names, though , in some cases, this may include extra information. For example, avsp.zip is named Alien vs. Predator (Euro 940520).

For reference, here is a link to the XML file ES uses: https://raw.githubusercontent.com/RetroPie/EmulationStation/master/resources/mamenames.xml

It's the ' (Euro 940520)' bits I am editing out on the gamelist.xml. I just want the games listed with no bits and bobs tucked on the end. Some games have 'set 1' or 'prototype' etc in brackets. I want a nice tidy list like:

Revenge of Mike Myers
Revenge of the Monkey Army
Revenge of the Monkey Army II

@MikeLang Then scraping is the answer.

It is possible to scrape roms on a PC. You can then copy over the gamelist.xml, leaving the images on your PC.

For example, you can download a binary for your PC's OS for Steven Selph's Scraper from https://github.com/sselph/scraper/releases/tag/v1.4.6.

@dudleydes

That looks like exactly the kind of thing I am after but unfortunately it's all a bit too complicated for me to grasp. I downloaded scraper_windows_386, extracted it into a folder where there is an application called scraper but don't know how to proceed.

dudleydes

@MikeLang You need to run the app from the Command Prompt - the Wiki has examples.

The scraper_windows_386.zip is for 32-bit (older) systems. If you have a modern computer, then you will likely need the 64-bit version, scraper_windows_amd64.zip.

You may want to take a look at the Universal XML scraper which uses a GUI instead of the command line. There are videos on YouTube on how to use the scraper.

Here is the thread: https://retropie.org.uk/forum/topic/5291/soft-universal-xml-scraper-v2-easy-scrape-with-high-quality-picture.

@dudleydes

Still not really getting how to do this. This is what I am doing, create folder called 'arcade' on c:

Copy 20 roms into 'arcade' folder. Copy scraper.exe to 'arcade' folder and then run in command prompt.

Get message 'It appears that thegamesdb isn't set up.'

dudleydes

@MikeLang You can try a source other TheGamesDB - Screenscraper.fr is probably considered best. Selph's scraper also needs to be run in MAME mode.

Try the command: scraper -mame -mame_src ss

[EDIT: changed -console-src to -mame-src]

MikeLang

@dudleydes

I typed 'scraper -mame -mame_src ss' in command prompt, just get a lot of text:

'flag provided but not defined: -mame_scr'
'-workers N'
'use N worker threads to process roms. (default 1)'

'flag provided but not defined: -mame_scr'

You said you entered -mame_src, yet the error says that you entered -mame_scr (which would be wrong). Which one is the typo?

MikeLang

@Clyde

Yep, that's what I've done, typed it wrong. It's working now but the gamelist.xml it generates has a synopsis of the game. I only want these bits:

<game>
<path>./Gamename.zip</path>
<name>Game Name</name>
</game>

If that is possible. Really appreciating all the help.

dudleydes

EDIT: Ignore - please see @mitu's suggestion below.

@MikeLang You can use the sed command. This is a Linux command so it will have to be done on your Pi. I recommend that you use SSH so that the command can copied and pasted.

First, use cd to change the directory to the one containing your gamelist.xml file, then run:

sed '/<desc>\|<image>\|<rating>\|<releasedate>\|<developer>\|<publisher>\|<genre>\|<players>/d' gamelist.xml

This command will output to the terminal what the amended version of gamelist.xml will look like.

If you're happy, then you can run the command below to commit the changes. This will overwrite your gamelist.xml file so good idea to keep a copy of the the original.

sed -i '/<desc>\|<image>\|<rating>\|<releasedate>\|<developer>\|<publisher>\|<genre>\|<players>/d' gamelist.xml

The only concern is when the <desc> entry runs for more than one paragraph. The sed will not catch the second and subsequent paragraphs. There's probably a way to include these but I don't know of any.

Extra paragraphs will make the XML file invalid as it will have unmatched tags and ES may not load. The extra paragraphs can be manually deleted in a text editor searching for </desc> string.

mitu

@dudleydes It's easier with xmlstarlet:

xmlstarlet ed -d '//game/desc' gamelist.xml

will delete all desc child nodes of the game node. Repeat for any other tag you'd like removed (favorite/image/video/etc.).

Already stuck, running putty, don't know how to change directory from 'pi@retropie:/ $' to:
