'Development builds directly from Git'

[TheDax]

They're exactly what they sound like: bleeding-edge development builds that have new features and (possibly, but not usually) new instabilities/crashing issues.

To use them, just install it like any other PPSSPP you use(on Windows, just extract the zip and overwrite your PPSSPP folder with it if you have one already). On Android, you might have to uninstall the Google Play version first before installing over it with the APK file you downloaded.

For example, here's what you're missing out on by staying on 0.9.1 official (see What's New in 0.9.5): https://github.com/hrydgard/ppsspp/blob/.../README.md
