One example would be /opt/retropie/configs/atari800/atari800.cfg All non-libretro cores also tend to have these. opt/retropie/configs//.cfg Some cores have their own config files for settings not covered by Retroarch. If you ever need to reset this file to defaults, there is a /opt/retropie/configs/all/-distfile that contains the defaults that you can copy and rename. Unless you have “Save on exit” enabled (which isn’t recommended), it will only save when you manually hit Save Configuration (which is different from Save Core Override). This covers the options for everything in the RGUI except the Options screen. opt/retropie/configs/all/retroarch.cfg This is the base retroarch.cfg-compatible file.

In fact, I don’t even recall where exactly my setup may deviate from the default. So this is a general guide, not something that will be 100% accurate for your specific setup. Some of the various scripts and packages to set up config files may choose different structures for them too. Some of these files point at others of these files, so it’s possible to end up with a different folder structure for where things live! Overlays, for example, can be done in several ways. If you intend to dive in, it’s worth reading. There is a skeleton version of this file located at /opt/retropie/emulators/retroarch/retroarch.cfg which has comments explaining the options. All “retroarch.cfg compatible” accept the exact same keys, and are all in keyname = 'value' format, e.g. Most of the below are what I would call “retroarch.cfg compatible.” Often this means they are literally in a file called “retroarch.cfg”, just in different folders. You may also want to look at the Libretro docs which have additional detail. There’s also documentation on the Wiki but I don’t think it covers everything. Here’s a list of all the ones I know of that affect this sort of option (there are plenty more that affect other sorts of options, such as emulators.cfg which controls what emulators try to boot a given rom). Oh… there are so many other places they are stored.

I started it as a reply to that thread, but it got so big that it quickly seemed to merit its own post so that others could see it too.Īre game specific configs stored somewhere other than the ROM folder? Over in the thread “Configuration changes not saving on x86 Retropie” asked “Are game specific configs stored somewhere other than the ROM folder?” And my answer got out of hand.
