New Version Won't Play Games I've Played on Old

[LunaMoo]

Redistributables are irrelevant, PPSSPP has libraries statically linked(aka they're part of the executable and system ones aren't used).
Also we don't use VS 2013 for a very long time, only VS2015 and VS2017 are currently supported, well there's I believe also mingw, but it's just bad and official builds will not be based on it. Either way downloading and installing "Visual C++ Redistributable Packages for Visual Studio 2013" would have no effect on PPSSPP.


Depending on hardware, problems would most likely be caused by bad Vulkan or OGL driver support. So yeah changing the backend is the thing that will most likely help.
Generally all backends currently are pretty good, but also will suffer from different issues, some of which will be hardware/driver dependant, some others not. Most of the code is shared between different backends, so differences outside of driver/stability issues are pretty minor mostly related to depth and lighting.

Also another thing I thought of before posting, when updating very old ppsspp to new one, make sure to update all it's folders, not just exe since some things moved around(ie missing fonts would crash some games;p) and some others were added, we also now have some compatibility hacks and features activated through external asset file which should be updated as well.
