scrap mame games information and images
Scrap mame games information and images from ‘mame.bigode.net’ or ‘adb.arcadeitalia.net’ and generate a xml for use with EmulationStation.
The purpose of this scraper is to be simple and fast. Currently it supports two sources with drastically different scraping methodologies.
The default source (bigode) is a lot faster because the scraper will download an entire mame database (1.1MB compressed) and scrap all the games information in one go. Besides that, this source uses a CDN and a very fast webserver to serve the images, resulting in faster responses and downloading speed overall.
The adb source is a more traditional approach, for each game found, the scraper will do a http request to get the information needed and then will download the appropriate image.
It is important to note that the images flyers on ‘bigode’ source are smaller in size, because they have a fixed 400 width.
To illustrate the difference in scraping speed, the following shows the time spent scraping an entire mame 037b5 set (2241 roms) on both sources:
Command: mamescraper -w 10 -i title Time spent: 1m 10s
Command: mamescraper -w 10 -i title -s adb Time spent: 8m 29s
Note that mamescraper was run with 10 workers and scraping titles only. If ran in ‘mixed’ image mode (default) the difference is even higher, since images flyers are bigger on adb:
Command: mamescraper -w 10 Time spent: 2m 2s
Command: mamescraper -w 10 -s adb Time spent: 26m 47s
Based on that, the recommended way is to run using the default ‘bigode’ source and if a game is not found, just run the scraper again in ‘append’ mode (to scan only the missing games) using ‘adb’ as source.
A huge thanks for AntoPISA creator of Progetto Snaps for the images and tons of mame resources.
Also, a huge thanks to Motoschifo creator of Arcade Database for the awesome arcade database website.
Install using pip:
pip install mamescraper
Download and set executable permission on the script file:
chmod +x mamescraper.py
Download and run using the python interpreter:
Download the Windows executable file from the releases page.
Usage: mamescraper.py [options] scrap mame games information and images from 'mame.bigode.net' or 'adb.arcadeitalia.net' Options: --version show program's version number and exit -h, --help show this help message and exit -a, --append scrap only missing roms from output file and append it to the file (default: disabled) -d ROMS_DIR directory containing the games (default: current directory) -e IMAGES_DIR_NAME directory name to download the images (default: images) -f FORMAT file format of the games: 'zip' or '7z' (default: zip) -i IMAGES images type: 'mixed', 'title' or 'flyer' - mixed will download a flyer and fallback to title if a flyer is not found (default: mixed) -o OUTPUT_FILE the xml file that will be created (default: gamelist.xml) -s SOURCE information and images source: 'bigode' or 'adb' (default: bigode) -w WORKERS number of workers threads to use (default: 5)
Simplest use case is to run on the mame games directory itself:
$ cd my_games_dir $ mamescraper
Alternatively, you can pass the directory to the scraper:
$ mamescraper -d path_to_games_dir
Scrap only missing games in the existing ‘gamelist.xml’ file:
$ mamescraper -a
It is useful for scrap on both sources if a game is not found. Just run the scraper a second time with append enable and a different source:
$ mamescraper $ mamescraper -a -s adb
If you have games in mixed formats, the following will run the first time scraping games in ‘zip’ format (default) and the second time appending the missing games in ‘7z’ format:
$ mamescraper $ mamescraper -a -f 7z
Run with 10 workers downloading only titles images:
$ mamescraper -i title -w 10
- Works on Python 2
- Tested on Linux and Windows, but should work on all platforms
- Uses only Python standard library for maximum compatibility
