Where are the old ppsspp dev builds

[LunaMoo]

You can always build it yourself using this detailed guide for windows or brief build instructions for other os's. There are also few older builds like 0.9.5/6 on the download page.

The reason why there's no more older builds is very simple, Orphis probably deleted them, he provides buildbot free of charge for many different emulators and from time to time has to delete older builds of very active projects to keep it going.

BTW if you're the same mckimiaklopa that spams github about "MT issue" for satan's sake or whatever god you belive in, this is not a bug so if this is what you need to test older builds for, then forget it. Your device is bottlenecked by weak gpu, same would happen when you would try to run heavy pc game like BF4 on typical office pc aka decent cpu + integrated gpu.
