Looking for old blueMSX_libretro.so core

Does anyone keep old cores? I’m trying to find a blueMSX_libretro.so that works with my Raspberry Pi 3 Lakka, problem is, my Lakka is old and Im not ready to upgrade yet.

The Lakka file I installed is named: Lakka-RPi2.arm-devel-20161221184608-r21729-g274b40f.img

Thanks
