Where to (legally) acquire content to play on RetroPie

@elco2 well I tried Ghost and Goblins, The data is more obvious, but still unclear how it relates to mame format. Here are the files that came out (with many more 0's on the front but I cut that off:
00.dat 155.95kb
01.mam 118b
02.mam 142b
03.pfb 331b
04.3ds 26b
05.dat 161.11kb
06.3ds 26b
07.scn 665b

You can use mame standalone (latest version) to check which files it uses from a romset.
There are a few Ghost and Goblin versions :
gng (Ghosts'n Goblins (World? set 1)
gnga (Ghosts'n Goblins (World? set 2)
gngbl (Ghosts'n Goblins (bootleg with Cross)
gngblita (Ghosts'n Goblins (Italian bootleg, harder)
gngc (Ghosts'n Goblins (World? set 3)
gngprot (Ghosts'n Goblins (prototype)
gngt (Ghosts'n Goblins (US)

You can check the romsets of each version with this command (if you installed mame from the exp packages) (use gng or something else) :

/opt/retropie/emulators/mame/mame -listroms gng

It will display the filenames,sizes and sha1sums.
So if you have a sha1sum that matches, but your filename is different, then you can just rename your file to that specific name, listed by mame.
When you have gathered all the files then you can repack these files to a working zip.

Your files don't come close to the files in the mame romset.

Sometimes romfiles are joined and then you have to split them.
But seeing your files the sizes are not duplicated of 16k or something like that.

So I think you just have wrong files.

@Folly Thanks for the help. These files came out of re_dlc_stm_1556690.pak , which I think is the correct one for G&G. Perhaps the unpaker is not unpaking correctly anymore?

@elco2

Indeed that could be the problem.
Can't help you with that.

Perhaps someone else knows.

@Crush [ROM extracted from Capcom Belt Action Collection (Steam version).]removed.
The site is in Japanese, extraction is possible.
However, you need to create your own CPS2key.
Some ROMs have problems with CRCs and sound ROMs.

@mochimochi Please don't post links to ROMs, as per the forum rules.

@mitu NoROM site!!! convert script!!

Does global mean only English-speaking countries?
Are you a global administrator who cannot even view Japanese blogs through google translate?
I don't understand why you are deleting this when there is no legal problem and it doesn't conflict with the forum rules.

Successfully extracted games from Intellivision following these instructions:
Intellivision Lives (PS2) / EAN 5060057021798

Also extracted files from ColecoVision Flashback purchased on Steam:

Colecovision Flashback 40 Game Pack ROM Extractor

Only had to rename *.cv to *.col after running that script.

Has anyone tried running the ROMs from the Neogeo Pocket titles available on Steam in an emulator? I tried the Steam versions directly and the input lag was horrible. I'm fairly sure the originals weren't like this, curious if it's just a lousy emulator being used.

Auster

@SeeNoWeevil I didn't test those games yet, but usually, official emulator wrappers are either poorly optimized/configured, or outdated, or both. You'll probably have better results running them from an emulator of your choice. Btw, iirc, all the files you need to emulate them, BIOS included, can be found in the files of this NeoGeo Pocket bundle.

themazingness

@SeeNoWeevil I haven't noticed any input lag using an SN30 Pro or a Dualshock 4. I've played on my Android phone in RetroArch and an Intel based PC in Retroarch and the wrapper by Code Mystics.

I might have experienced it with Fatal Fury. I did find it difficult to pull off S moves, so maybe there? I just assumed it was my lack of skills since the rest worked fine, but I don't have experience on the actual hardware so I'd be ignorant of any discrepancies.

Thanks both. I actually refunded the games on Steam due to the lag. I may give them another try. Perhaps I'm just not used to a 30fps fighting game.

Does anyone know why Raiden Fighters 1 is the only one that doesn't seem to work in the Raiden Legacy Collection? All the other ROMs work, I've tried every core pretty much.

Capcom Beat 'Em Up Bundle

Thanks. :) Worked for me on Linux.

Installed the game via Steam (Wine) and moved game_xx.arc (xx= 00,01, 10, 11, 20,21,30,31,40,41,50,51,60 or 61) to a seperate folder (working directory).
Installed Universal Extractor 2 via PlayOnLinux
Extracted all files (game_xx.arc) via Universal Extractor 2 in my seperate folder.
Unzipped CBEUB_extract.zip and put all extracted files from the folders found under game_xx/bin.
Ran the batch files via wineconsole gamexx_filename.bat from the terminal.
A new temporary folder tmp appears and the files will be stored here.

These files have to be zipped and named manually because the script isn't for Linux. Move the .zip-file to another folder, delete all files in tmp and run the next .bat-file.

Edit: Extraction worked but some files seem to be missing. I'll check it...

I found a new script in Python created by shawngmc

Capcom Beat 'Em Up Bundle,Capcom Arcade Stadium 1 - Game ID 1515950 - Old version and Capcom Fighting Collection can also be extracted.
There was also a summary of the working status of the extracted ROMs.

It worked fine on Windows 10, but could not be installed on Ubuntu on WSL because it requires python-magic-bin.

On windows
Use pipx\venvs\game-extraction-toolbox\script\gextoolbox.exe.

The format is
gextoolbox.exe postprocess steam extract --srcdir (Steam game install or downloaded Depot folder) --destdir (destination folder) --task (supported game name)

--task should be the name of the corresponding cas1_old,cbeub,cfc,sf30ac

Dear global administrators, no illegal links:)

@mochimochi Hey, thanks for the shout out!

I'm Shawn, the developer of that tool., which has two main goals:

I want to make some quick command line tools to help rapidly prototype extraction methods from these various collections
I've been poring through disparate scripts trying to find one-off scripts that can be incorporated.

I'm always on the lookout for more games to add - in an upcoming release (likely 0.0.21), I'm adding:

Blizzard Arcade Collection
Bubsy Two-Fur
Collection of SaGa/Final Fantasy Legend
Mega Man Legacy Collection 1
Mega Man X Legacy Collection 1

Most of this batch is low hanging fruit (rename files, extract contiguous chunks of large files, etc.), but I'm hoping to add some more soon.

I'm also trying to keep this 'as legal as possible'. By that, I mean no redistribution of any copyrighted material or encryption keys that would trigger a DMCA request.

This thread has been a huge help to my legal ROM collection, so hopefully I can help give back a bit. I'm also open to game/collection suggestions or generic tooling to help investigate these games.

One more thing:
In that upcoming version, I've also simplified the command structure a bit as this tool has taken shape. The equivalent of the command @mochimochi had is now:

gextoolbox.exe tasks extract --task <TASKNAME> --srcdir <PATH/TO/SRC> --destdir <PATH/TO/DEST>

It now also has 'sane defaults' on Windows (if your Steam library is in the default location, you can fully omit the --srcdir flag).

To get a list of the tasks, you'll use:
gextoolbox.exe tasks list

And to get more details on a task, you'll use:
gextoolbox.exe tasks details --task <TASKNAME>

mochimochi

@itomeshi Hi,I'm glad you made a good extraction tool!

It would be very useful if we could convert multiple titles with one tool.
I know it's hard to keep up with the development, Good luck!

@itomeshi
Hi, tried this for Capcom stadium 1. Only had 1 DLC, but it sorted out that I only had 1943 and gng. It looked like it worked... however when I went to the destdir (that it had made) it was empty :/
