Datoso

Datoso is a WIP Python command line tool to download and organize your Dat Roms. As today the tool supports dat-omatic, redump, and translated-english dats. It merges all the dats in a tree folder structure thought to use with Emulators rather than dats. The dat file format must be compatible with ROMVault.

Features

• It can download dats from different sources (dat-omatic, redump, translated-english)
• It can process dats to generate a folder structure compatible with emulators
• It can deduplicate dats
• It can import dats from existing RomVault
• It can mark MIA roms

Installation

Datoso requires python 3.10+.

Use pip (recommended to use a virtual environment):

# Optional (create a virtual environment)
python3 -m venv venv
source venv/bin/activate

# Install datoso base (doesn't do much without plugins)
pip install datoso

# Install datoso with all official plugins
pip install datoso[all]

# Install datoso with only one of the plugins
pip install datoso[fbneo]
pip install datoso[nointro]
pip install datoso[pleasuredome]
pip install datoso[redump]
pip install datoso[translatedenglish]

# Install datoso plugins after installing datoso
pip install datoso_seed_fbneo
pip install datoso_seed_nointro
pip install datoso_seed_pleasuredome
pip install datoso_seed_redump
pip install datoso_seed_translatedenglish

$ datoso --help

usage: datoso [-h] [-v] {config,doctor,dat,seed,import,deduper,all} ...

# Seed commands
$ datoso seed [list,details]

# Seed commands
$ datoso {<seed> | all} {--fetch | --process} [--filter FILTER]
#e.g.
$ datoso redump --fetch                    # Downloads all dats from redump
$ datoso redump --process --filter IBM     # Process all dats downloaded in the step before that has IBM in its name

# Doctor
$ datoso doctor [seed]        # Validates if all requirements for all seeds are OK

# Deduper
$ datoso deduper -input <input_dat> -p <parent_dat> [-o <output_dat>]   # If output dat is not especified, input dat will be overwritten.

optional arguments:
   -h, --help            show the help message and exit, feel free to append to other commands
   -v, --verbose         verbose output
   -q, --quiet           quiet output

Posible Issues

Be careful when updating dats from datomatic, sometimes they put a captcha, and you may be banned if the captcha fails, captcha support is OTW.

TODO (without priority)

• Change logo
• Change pydantic to dataclasses
• Better rules update process
  • Make update rules write to database only when finished
• Tests
• More dat repositories
• Mega.nz download support (https://pypi.org/project/mega.py/)
• Zippyshare download support (https://pypi.org/project/zippyshare-downloader/)
• Zippyshare download support (https://pypi.org/project/pyOneFichierClient/)
• Configurable folder structure (instead of emulator-focused structure use dat-repositories or viceversa)
  • Maybe with a builder, to avoid the need to change the code anytime

USEFUL DEVELOPMENT COMMANDS

# Find folders with more than one dat file:
$ find . -type f -iname '*.dat' -printf '%h\n'|sort|uniq -cd

# Find and delete empty folders:
$ find . -type d -empty -print -delete

# Pylint
$ pylint src --errors-only
$ pylint src --disable=all --enable=missing-function-docstring

# Find duplicate names different case
$ find . | sort -f | uniq -i -d

WISHLIST (without priority)

• Dat structure for ClrMamePro or another dat manager.
• Web interface
• Download from central repositories (an S3 or something like that to prevent overload main sites)
  • Lambda to download dats and upload to S3
  • Downloading from S3
• Auto-Import MIA Lists (for redump)
  • Add [MIA] to dat roms (DONE)
• Remove MIA from dats (probably not needed as it already can mark them)
• .cue Generator
