Import ROMs into Mame

jak75

So basically you get the ROMs first and then try the emulators to find the one that makes them work right?

No, that only applies to ROMs which you buy, for which you don't know the Romset version. For other methods, please read the doc page that was posted a few times already in this topic.

But how can I purchase ROMs with a license? Nothing can be found.

There's a long topic over here with options on where and how to buy games, including arcade games.

I connect via winscp, I see the "Retropie" folder and inside this there is the "Roms" folder inside which there is the "Arcade" folder inside which there is the "Mame2003" folder. Are there other folders inside Mame2003, the game roms, which are .zip files should they be placed inside the "Mame2003" folder?

@jak75 The subdirectories are "meta-data"-folders from the emulators (configs, etc.)!
roms should be placed inside the rom-folder for the system (not in any (precreated) subdirectory therein (and whence using subdirectories - which is possible (and in some cases advisable) you should be aware and knowing of the why & if you are not, then you haven't reached the RTFM and customization point where you may need 'em!), and chds are another topic we may talk about later) the reason why the emulators are opening their own subfolder in those rom directories is (simply phrased) because multiple emulators could utilize/draw from that rom folder and each of them stores their meta-data for a particular rom in the emulator specific sub-folder!

Hi, after uploading the rom zips to the "Roms" folder in Emulation Station, where should you see the games to start them?
Thank you.

You should see them in the system where you copied the ROM. If you copied them in thearcade folder, then they'll show up in the Arcade system, if you copied them in the neogeo fodler, they'll show up in the Neogeo system, etc.
After copying the files, you need to restart EmulationStation (which you can do so from it's menu) to see the new games/ROMs.

@mitu Hi, I see them from the emulation station file manager, but I don't understand how to start them, basically from the file manager I see them as zips, shouldn't the games icon appear on the emulation station, I don't know?

mitu

@jak75 Please provide a picture of the files, as they appear in the file manager. In which folder did you copy the files ?

I copied the zip files to the "Roms" folder not its subfolders.
I don't know how to take a screenshot using Retropie, how do I do it?

Then that's why they don't work, you need to copy then to the corresponding subfolder - if they are arcade ROMs, choose the arcade subfolder, if they are NES ROMs then use the nes subfolder, etc. Each system/console has it's own subfolder where you need to copy the correspomding ROMs. Check out the Docs, where each system is listed along with it's corresponding subfolder and known file extensions.

I don't know how to take a screenshot using Retropie, how do I do it?

A mobile phone or a camera should work.

Hi, here's what I see, the roms have been transferred, they are the zip files at the bottom, but I don't understand how to start the games, thanks.

@jak75
You have to add the roms into corresponding folder. For what system are the roms ?

If they are Mame roms you have to add them into /arcade folder.

I consider it necessary to read the Wiki about arcade emulation:
https://retropie.org.uk/docs/MAME/

Re-read my previous reply - find the right sub-folder for the games and copy the roms in the corresponding sub-folder.

jak75

@abj Hi, thank you for your patience! Inside the "roms" folder there is the "arcade" folder and inside the arcade folder there are the "mame2003" and "advmame" folders, both folders then have other subfolders.
But now I have a doubt whether the roms are for mame2003, how can I check it? Do the roms go inside the "mame2003" folder anyway?

abj

@jak75
Ignore the other folders, just add the roms into /arcade and you are ready.

jak75

@abj Ok it works, a wonderful message appeared in Emulationstation saying "3 Games available" wonderful!
But the games don't load and you are told to look at the logs in the file:
/dev/log/shm/runcommand.log
I can't find this file, what folder should it be in?

abj

@jak75

We need runcommand.log file the location for this file is /dev/log/shm .

Arcade games aren't like consoles games (snea, nes...). You have to much the rom set with emulator you want to use. Please read the docs about arcade games, it will help a lot :https://retropie.org.uk/docs/MAME/

jak75

@abj All the patience in the world! Thank you! I didn't understand correctly, sorry, the problem is that these roms are not suitable for "mame2003"?
The path to the log file, I can't find it, there must be a "dev" folder?

abj

@jak75

For lr-mame2003 you need the MAME 0.78 Rom set version.

This means that you have to search for mame 0.78 roms.

Ok solved! But now I have another problem, the game pad was recognized by emulationstation but when I launch the game it doesn't respond at all, no buttons, and then I can't hear the audio, any advice? Thanks for your patience!

Hi, the games are playing, I tried to look in the audio configuration and the output device seems correct, when the games start this message appears !Press button to configure, errors are logged to /dev/shm/runcommand.log" but I can't find this path, where should it be? I don't see a "dev" folder, can you help me?
