where can i download older versions of ppsspp? like 0.9.5 or before that...

If you mean old git builds, they're pretty much gone, unless you want to risk getting builds from shady sites like emucr, or compile them yourself. If you mean old stable releases, you can change the current PPSSPP download link URL to grab old ones:

http://ppsspp.org/files/0_9_6/ppsspp_win.zip <- See the 0_9_6 part? Change it to 0_8_1 for example, and you'll get 0.8.1. Unless they've been removed, we have builds dating all the way back to 0.1, I think. This only works for Windows, though.

For Android, it's the same deal:
http://ppsspp.org/files/0_8_1/ppsspp.apk <- change 0_8_1 to whatever old version you need for Android.

If you need old builds for Linux, Mac or iOS, well, you'll need to compile them yourself.
