#### PSP
* Build pspsdk(GCC 9.3) from https://github.com/pspdev

@@ -90,3 +94,20 @@ If compiling 32-bit on amd64, you may need to supply `export PKG_CONFIG_PATH=/us
(You need to pass `-8` to compile 64-bit engine on 64-bit x86 processor)
2) Compile: `./waf build`
3) Install(optional): `./waf install --destdir=/path/to/any/output/directory`
#### PSP
0) Navigate to `xash3d-fwgs` directory.
1) Examine which build options are available: `./waf --help`
2) Configure build:
Normal: `./waf configure -T fast --psp=prx,660,HW --prefix=/path/to/any/output/directory`
Profiling: `./waf configure -T debug --psp=elf,660,HW --enable-profiling --prefix=/path/to/any/output/directory`
3) Compile: `./waf build`
4) Install(optional): `./waf install`
## Running
0) Copy libraries and main executable somewhere, if you're skipped installation stage.
1) Copy game files to same directory
2) Run `xash3d.exe`/`xash3d.sh`/`xash3d` depending on which platform you're using.
For additional info, run Xash3D with `-help` command line key.
