I feel like we are trying to solve the wrong problem here.

Indeed so. What makes you think that adding the extension to the list will make the ROM actually work ?. Are you sure that the emulator you're using supports .zip files ? Have you installed the lr-mupen64plus emulator, it's the only one that has .zip file support.

EDIT: the reason the es_systems.cfg file you copied is not writeable is because you have to give the pi user permission to write it. Run

sudo chown pi:pi <path_to_file>

and it should be editable.

Because I copied the ROMs over and the N64 ROMS where the only ones that didn't show. I investigated and someone had the same issue, added the .ZIP file extension to es_systems.cfg and saved and all was good. It is the lr-mupen64plus emulator I am using. I haven't installed anything else. I've literally got my Pi and installed Retropie.

I've just ran that command successfully and I still can't save the file once edited with WINSCP.

Can you run

ls -l /opt/retropie/configs/all/emulationstation/es_systems.cfg

and post the output ? What is the actual file name you've copied and it doesn't show up ?

Dinsdale

-rw-r--r-- 1 pi pi 11296 Oct 21 19:50 /opt/retropie/configs/all/emulationstation/es_systems.cfg

I'm not sure if this is relevant, but I'm not logged in as "pi". I created a user and used this guide: https://raspi.tv/2012/how-to-create-a-new-user-on-raspberry-pi

It's quite relevant, since the RetroPie image you're using is using the pi user to run almost everything related to emulation and the configurations created take this into account.

Dinsdale

Bingo. Just successfully edited this... so, thank you - ok - I'll load a test ROM and see if the edit makes a difference HOWEVER, for security sake, I would like my new user to have the same permissions as Pi. How do I do that? I thought I did with the link I posted above.

mitu

@Dinsdale You don't - if you're not sure what your doing, please stick with the defaults and use the pi user for all intents and purposes. Is there a reason you want a different user ?

Dinsdale

It worked, by the way. The ROMs now show up.

Ok, I will - but in the interest of learning - where have I gone wrong assigning my permissions?

You’re right when you say I’m not sure what I’m doing, but I’m interested to learn.

Well, you actually didn't assign any permissions to your new user, you just set it to be able to run sudo. That blog post pre-dates the release of Raspbian (2013) and although the advice may be sound (i.e. use a non-default username), this approach has little security advantages for the problem it purposely tries to solve. If you want to be more secure, then change the password for the pi user to something non-trivial immediately after you set up your system. And don't expose it directly to the internet.

@mitu That makes sense. I understand. Thanks for your help!
