compiling direct x version

[LunaMoo]

This is probably a problem of this ANGLE build, and will not be fixed since it's not maintained or even supported by anyone.

If you cannot upgrade your hardware, you can only wait for proper DX9 support(there's no ETA, basically nobody knows when it'll happen, but alot of the job seems to be already done) or try updating your graphics drivers. I guess in few cases even if you couldn't find a good driver for windows, looking at this list of intel graphics some of those awfully unsupported(by intel itself:]) integrated graphics could easily handle PPSSPP on Linux while failing on Windows, it's especially visible in third gen.
