compiling direct x version

[Raimoo]

You need to patch and compile the source code of both ANGLE and PPSSPP. Like I said, the only issue is that the original poster didn't specify which version he patched against, so you're going to have to guess.

if you talking about which PPSSPP version used for the new patch, its the latest official build which is v0.9.6. (I've read through the forums in Nvidia forum)

Note that there are some issue with z-buffer with the new patch and they are currently try to fixed it.
