Questions about GPi

soldomino

Hey guys, I just got a GPi case and a RasPi Zero and I’m new to this RetroPie stuff. I just had a couple questions that hopefully you can help me with.

How can I edit game metadata? The scraper couldn’t pick up a few games and it doesn’t have a keyboard to a manual edit. Is there a workaround?
Are the roms saved to the SD card or the RasPi computer? I can see all the roms when I connect to the Pi but when I plug the SD card in, I don’t see any of the roms.
Has anyone else had problem with lagging? I was trying out some SNES games and they all ran so slow. Any fixes for this?

Thanks for any help you can provide.

How can I edit game metadata? The scraper couldn’t pick up a few games and it doesn’t have a keyboard to a manual edit. Is there a workaround?

If you have the wireless enabled Pi0 model, then you can edit the gamelist directly over the network - it's an XML file in \\retropie\configs\all\emulationstation\gamelists\<system_folder>. Make sure you do your edits while EmulationStation is stopped, otherwise they might get overwritten when EmulationStation shuts down.

Are the roms saved to the SD card or the RasPi computer? I can see all the roms when I connect to the Pi but when I plug the SD card in, I don’t see any of the roms.

Windows doesn't see the Linux partition on the card where the OS and all data is stored. You see only the boot partition, a smaller portion of the card that's formatted with a Windows compatible file system.

Has anyone else had problem with lagging? I was trying out some SNES games and they all ran so slow. Any fixes for this?

SNES is approaching the upper limits of the Pi 0 for emulation, but you can choose one of the older (and less accurate) emulators available - see the SNES page on what emulators are available.

@mitu Ok, cool. Thanks for the advice! Knowing that will help me whittle down what games I should put on there (SNES Doom, Star Fox, and really any Mode 7 stuff was lagging pretty bad). Now, I'm probably just dumb, but how do you access that folder? I was digging through the files and couldn't find that directory path. I'm viewing the Pi using WinSCP, if that matters.

If you're using SSH to access your Pi, then you can look at/opt/retropie/configs/all/emulationstation/gamelists, it's basically the same folder.

I think that even with older/less accurate emulation, you won't be able to emulate SuperFX games full speed on a Pi 0.
