Install msys.
Follow the guide here to set up your MSYS installation for retroarch compilation:
https://docs.libretro.com/development/retroarch/compilation/windows/
You can probably really skip most of the packages but you need make:
pacman -S make
"Install" the plugin in Retroarch.
Then use the following in msys:
cd libretro
make platform=windows_msvc2019_desktop_x64 -j32 && cp ppsspp_libretro.* /d/retroarch/cores
Note that the latter part copies the DLL/PDB into wherever retroarch reads it from. Might need to adjust the path,
and adjust -j32 depending on your number of logical CPUs - might not need that many threads (or you might need more...).
(plain make without a platform parameter doesn't work - g++ isn't able to build the D3D11 stuff, or at least it fails to link).
To debug from within MSVC, open retroarch.exe (or retroarch_debug.exe) as a Project/Solution, then open a few of the cpp files,
set some breakpoints and just launch using F5.
Useful libretro/vulkan sample code:
