PSP is not yet supported. Some of y'all may have seen that I pushed a "beta" ppsspp core, but this core is not ready for daily use. It still crashes randomly and any games that use 3d (so like, all of them) will just have a white screen (and might just crash). Do not open issues related to the "psp" core.
