PS2SDK: The 2018-02 one. Most of the stuff precompiled in Linux, then copied to Windows. Linux executables does not works out of the box, but you can replace with the GSHI ones.
PS2SDKOLD: The GSHI one

PS2SDKOLDER: A special SDK I can not find anywhere online and luckily (thanks to a miracle) I have it.
