What's the problem? Describe what went wrong.
When Dolphin is given a path to search for playable games in the "Game Folders" option, it lists all found games in the main window. However, in version 5.0-7106, games will not show up in the list unless the file extension is all lowercase. For example, if your files end in ".GCM" rather than ".gcm" or ".WAD" rather than ".wad", they will not show up in the game list.

What steps will reproduce the problem?

Rename any game ROM files to have a capitalized file extension, close Dolphin (if it is running) and open Dolphin again. You won't find the game in the list anymore.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

This issue is present in Dolphin 5.0-7106.

Is the issue present in the latest stable version?

This issue is not present in Dolphin Stable 5.0.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

I'm not sure, I first noticed this issue in 5.0-7106.

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

Nothing else should be important here.

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
