Share your collections

[strangeruk]

I thought I would share with you all a bunch of collections I have made. I am not protesting that these are definitive, but they are certainly a good starting point! I hope that someone may find them useful:

• Batman Custom Collection
• Disney Custom Collection
• Donkey Kong Custom Collection
• Looney Tunes Custom Collection
• Mario Custom Collection
• Marvel Custom Collection
• Mortal Kombat Custom Collection
• Nes Classic Custom Collection
• Simpsons Custom Collection
• SNES Classic Custom Collection
• Sonic Custom Collection
• Street Fighter Custom Collection
• Zelda Custom Collection

I made a new Collection "gungames" for Remote Guns.
I used "Emulation Station for Windows"

Gun Games Custom Collection

I Handpicked the Best Gun Games of All Time. (without PS3 or XBox)

[thelostsoul]

I have a lot of collections. Can't post them now, as I am not at home. Every collection can have up to 13 games at max and are something to represent for what they are. Most of them are genres like racing or rpgs. I also have some of my favorite hidden gems or mods.
And there are those collections added through theme, which appear on main site between the consoles. These can have any number of games and currently I have Arcade, which contains games from Mame, FBA and Neo Geo. And the NES mini and Snes Mini collections and Shmup only too.

Not sure how posting these lists will help, as you may not have the same roms as I do. I have a mix of European, US and Japanese games for many consoles.

@thelostsoul Well... It's rather how far the game names hit the ROM Images. The description is something a bit weird.

What works 100% are CPS, MAME and NEOGEO games.
Other systems are try and error. The best way in sharing collections would be a script that automatically looks for rom names that looks very equal like

/home/pi/RetroPie/roms/gb/Tetris (JUE).gb
/home/pi/RetroPie/roms/gb/Tetris.zip
/home/pi/RetroPie/roms/gb/Tetris (Europa).gb
/home/pi/RetroPie/roms/gb/Tetris (Japan).gb

So you have 4 entries and that will give a regular hits for a rom collection. In the best way... Just 1

The rest of the collections entries are ignored... so we can easily share all collections ;)

[thelostsoul]

@cyperghost There are ton of pissibilities how files are named. Some have exclamation marks for good dumps, some US or EU or for German versions and even more. Also different type of collection sets do naming conventions differently. All these have to be multiplied with .zip and all supported filetypes for alle emulators a system is using. Translations, Homebrew and Mods of games, other manually added games are another thing with custom names. CD games also have often different filenames and aren't much standardized.

Which brings me to a point where a script for collection creation comes to my mind. I have no time for it now, but maybe I will create one.

[cyperghost]

@thelostsoul I made several attempts with bash. To strip braces I used this one
${name%% (*}
To get extension you can use this
${name##*.}

Usually the ROM is named like this shema

PATH TO ROM FILE/That is the ROM NAME (Region) [Dump state] !%$.EXTENSION
           |               |                                        |
  We strip this to/    Extract to (                        Save extension
   to get system

Then use find /path to your files for system/ROMNAME without(*.extensionfunction and then we are happy about.
If nothing found then find again but now without extension ;) We have to ignore *.srm and *.state* files for that case :(

@thelostsoul

Here is a bare script! It's bare because it will only operate if there is exactly one match. I don't strip path to roms, so there is no chance to find roms that are located in arcade folder can also be found in mame or fba folders.... So this is a very primitive workaround. Moreover, if you make several runs your gamelist will grow and grow and grow because I don't make crosschecks if file entries that can be modified are already in the lists....

But the idea is clear. Every user can make a run on his game collection and the collection file will increase and increase. With much luck we have a fileset that says. This collection has 21 games in but there are all in all 155 file entries. But this is because someone used zip files, other one got a bad dump.... And if all is good the user got exactly 21 entries in his collection on ES ;)

My first test with the BATMAN Collection ended in 9 "new" added entries ;)

/home/pi/RetroPie/roms/snes/Batman Forever (E) [!].smc
/home/pi/RetroPie/roms/snes/Batman Returns (U) [!].smc

Script ouput was:

File 1 found: batman.zip
File 2 found: Batman - Return of the Joker (U) [!].gb
File 2 found: Batman - The Animated Series (U).gb
File 2 found: Batman Forever (U) [!].gb
File 1 found: Batman Beyond - Return of the Joker (USA).zip
File 1 found: New Batman Adventures, The - Chaos in Gotham (USA).zip
File 3 found: Batman - Revenge of the Joker (U) [!].bin
File 3 found: Batman Forever (F) [!].bin
File 3 found: Batman Returns (U) [!].bin
File 3 found: Justice League Task Force (F) [!].bin
File 3 found: Batman Forever (E) [!].smc
File 3 found: Batman Returns (U) [!].smc

Means:
File 1 - 3 ROMs from collection were also located in my ROM folders --> 0 added
File 2 - stripped away all brackets and used same extension - 3 were added to collection
File 3 - stripped away brackets and extension - 6 were added to collection

@cloudlink
Thanks for this huge collection ;)
That's amazing!

Just for an example your Warner Bros Collection was translated by my script to this. So even you naming convention isn't "correct" I was able to get half of your settings on first run. I think that's okay....

But we have to dig deeper into somehow... Maybe checksums ;) But now we could merge your collection and mine in one file ;) The script needs a bit improvment.

It need a first loop with a check if files can in the whole collection are available and put it in an array with array+=("$romfile" "$available") so if file is available the $available will be setted to 1, else to 0 ;)

@cyperghost This is great!
I didn't test it out yet, but now we are talking. :D First, I want thank you for doing/starting this. I was thinking about this "problem" a while back and didn't know how to do it properly. I was more thinking of a Python script, but Bash is fine too. ;-) Currently I am doing other stuff. I'll test this later and will have a look into the script. From a different script I have, I use this to strip down the clutter from filename:

sed -i s/"(.*$"//g "$file"

which deletes everything after (including) the first brace. I use this to get a clean name of the filename for a quick list. But thats not gonna help for your script, as you use those different parts. What do you think about doing it like this: Strip down on both sides (custom collection and files) everything after brace and compare. Found identical entry, use original filename from drive and add to new collection. So, you don't deal with the clutter. Not sure about this approach, if it would work better. It just sounds more simple. What do you think about it?

Custom Collections with max. of 13 elements per collection:
The entries are like showcases for a specific genre or what they are for. I try to get different type of games for different systems. The systems in use are following: atari2600, mame2003, fba, neogeo, gamegear, gb, gba, gbc, megadrive, sega32x, mastersystem, nes, snes, pcengine, psx, n64. The SNES have two extensions, sfc and smc. PC Engine have two extensions, pce and cue.

Genre:

• Action
• Action Adventure
• Action Platformer
• Fighting
• Jump and Run
• Match Blocks
• Pinball and Paddle
• Puzzle Logic
• Racing
• RPG
• Scrolling Brawl
• SHMUPS
• Sport
• Strategy

Other:

• Movie and Comic
• Mods and Homebrew
• Multiplayer
• Highscores (Games I played on MAME ROW)

Insider Tips:

• Arcade Insider Tips
• Mega Drive Insider Tips
• SNES Insider Tips

Custom Collections From Theme, for main front page without a limit in elements per collection:

• Arcade
• shmups
• NES Classic
• SNES Classic

Just a note here. I did a pre selection of games. That means, I often have only one or two best versions of games, with some exception. In example:

• I have Earthworm Jim for SNES, because I grew up with it. Found out, the Mega Drive/Genesis version is better, but excluded it for not having duplicates, even if there are differences. Finally added the Mega CD/Sega CD version of the game, as definitive version.
• I have Street Fighter 2 versions (Super, Turbo) for SNES and Arcade. Because I play Console versions with gamepad and Arcade versions with arcade stick. And there are duplicates for some personal reason.
• I often have only one version of a game, in example the Arcade versions. In example of Bubble Bobble, later I added the NES version to be able to build the correct NES Mini collection.

It just sounds more simple. What do you think about it?

The collection needs to fit exactly with file pathes. So the way how to strip down bash internal, sed, python isn't important. Important is, how the files can be retrieved. The bash script here works in 3 levels:

1. Just compare file name, is 1 is returned everything is fine if 0 (=no file found) then go to level 2
2. Compare filename with stripped brackets and original file extension. If one file os found (returns 1) then add the file to collection. If no file is found(0 returned) go to level 3
3. Compare filename with stripped bracktes and ignore file extension. If one file is found then add to collection, if 0 is returned then make nothing else.

You see fail by design. If 2 entries are found then the script also fails ;) As I said: I can live with that becasue I have no savegames or SRM-states in my ROM folder.

Annother (maybe better) approach would be following.

We use a tool like md5tree and all roms will be scanned for md5 checksum. So we have filename and it's checksum stored in one huge file. We call it md5_romcollection.dat

But this won't save us if someone uses zipped files. But let us be independent of file pathes. I must think about it a bit. I can work with the script I coded ... it covers 75% of my usecase but it's not coded in a good manner and uses unnecessary uses cases and selections.

I would be glad if someone else would step in...

[thelostsoul]

@cyperghost My idea was using wildcards to get full filename. So strip the clutter path and find file with wildcard. In example "find Bik*" gives me "Biker Mice From Mars (U) [!].smc". Ok, the save files have to be filtered out. Maybe this can be used? This could be used as fallback, if exact filename of different variations aren't found. The md5checksum approach would be good too, but custom collections don't have a md5checksum. And what do you think about stripping down the "-" between Batman and its subtitle and all spaces, plus making everything lower case while comparing?

[cyperghost]

@thelostsoul That's exactly how it's working
Look: match=$(find "${line%% (*}"*) cuts all charcters till the braket appears and set a wildcard * - that's the searchstring for level 3. So it fits exact your example.

In level 2: match=$(find "${line%% (*}"*."${line##*.}")this cuts all charcater till the braket and set a wildcard * but with extension retrieved from the custom collection.

Your example would be proccesed in my script like following
level 1 - find Biker Mice From Mars (U) [!].smc
level 2 - find Biker Mice From Mars*.smc
level 3 - find Biker Mice From Mars*

I think to filter out all possibles filenames will be a good choice. And the more people share the collections the more the chance to get a full working collection. But as I said I'm satisfied how the script is working. But there is space for lot's of improvements.

See... level 3 is very critical

Because it will also find
Biker Mice From Mars II (U) [!].smc or Biker Mice From Mars (U) [!].smr or Biker Mice From Mars (U) [b].smc or Biker Mice From Mars (J) [!].smc or even worse Biker Mice From Mars (U) [!].autostate

But now I've an idea...... ;)
Why not ask the user for right choice?
So if more then one entry appears open a dialog and ask the user for input.

Annother thing that has to be solved is.... if we process the custom collection.
Should we just add the new found entry? Or should we overwrite the existing one? Because if we just add a new entry we have to check the whole custom collection before we write anything because we will append data on every run. So the overwriting should be more solid! And that's a real easy sed command ;)

[thelostsoul]

@cyperghost OH man, sorry I was just blind. I only did a brief look into the script. And I forgot about all the other files, so a pure find Bik* would be really a bit greedy. I think asking the user wouldn't be good, its the job of the script to do this. After while with different collections, it could get annoying or the user chose wrong decision, say a noob did it.

Snes roms have mostly 2 different types, .sfc and .smc. Also .zip files are supported too. Maybe we could do it with ls and grep. I did this with a script of mine and it worked.

output="$(ls "$1" | grep -E ".$2")"

Variable $1 is the base directory where all files are. The final output of the command is saved in variable $output. I used this in another script as a function. Sorry for the German comments, it never was intended to release. But now, it helps explaining how I used it.

#!/bin/bash
# Important, this script was intended to be used under Linux / Ubuntu. Not on Raspberry Pi!
base="smb://retropie/roms/"
temp="./games.txt"

cd $base
rm "$temp" 2> /dev/null

# Listet und filtert Verzeichnisse nach Dateityp.
# Argumente: 
#   1 = Verzeichnis
#   2 = Dateityp
function lsfiles ()
{    
    # Führt ls Kommando aus und filtert jede Zeile durch grep.
    # "$()" Konstrukt ermöglicht es als Kommando auszuführen.
    # -E ist nötig, um mehrere Dateitypen zu ermöglichen.
    output="$(ls "$1" | grep -E ".$2")"
    # Speichert die Ausgabe der Variablen in der Datei.
    echo -e "$1\n$output\n" >> "$temp"
}

lsfiles "atari2600" "bin"
lsfiles "mame-libretro" "zip"
lsfiles "fba" "zip"
lsfiles "neogeo" "zip"
lsfiles "gamegear" "gg"
lsfiles "gb" "gb"
lsfiles "gba" "gba"
lsfiles "gbc" "gbc"
lsfiles "megadrive" "md"
lsfiles "sega32x" "32x"
lsfiles "mastersystem" "sms"
lsfiles "nes" "nes"
lsfiles "snes" "sfc|smc"
lsfiles "pcengine" "pce|cue"
lsfiles "psx" "cue"
lsfiles "n64" "z64"

# Pro Zeile, alles nach erstem Klammer löschen.
# -i ist nötig, damit es in der Datei gespeichert wird.
sed -i s/"(.*$"//g "$temp"

Try it manually with:

ls "./" | grep -E ".sfc|smc"

And then we have the filtered list.

[cyperghost]

@thelostsoul I understand the comments ;) And this will create a list of ROMs without brackets and extension.

But I would stick to find this supports RegEx so wie can include/exclude filetypes ;) and more...

1. I would also use the level model
2. I would use sed to directly modify custom collection file rather to add a new entry
3. Then there are special folder like neogeo/cps/fab/aracade/mame ;) These should be investigated step by step ;)

[thelostsoul]

Ok, back to plan A. :D

[cyperghost]

@thelostsoul Definitly use find it outmatches ls easily. I think I can provide a working script for all usecases. But thank you for posting your script. It gives me inspiration.

[cyperghost]

@thelostsoul I trying to write a script ...
Followup is here Pathfinder for custom collections

[cyperghost]

Updated main topic ... We can now use filefinder script to use collections from other users with the personal rom-set
Thanks to @thelostsoul for testing and @pjft for developing the custom collections feature for ES ;)
