ok, I’ll post a small guide on building cores, so hopefully someone will make a repo of cpi enhanced cores:
always run this first:
export TARGET=~/.config/retroarch/cores/
mkdir -p ~/repositories/cores
picodrive working perfect, full speed on sonic 3
cd ~/repositories/cores
git clone https://github.com/libretro/picodrive.git picodrive
cd picodrive
git fetch origin && git reset --hard origin/master
git submodule update --init
make -f Makefile.libretro -j2 platform="armv neon hardfloat"
cp -v *.so $TARGET
pcsx_rearmed working perfect, full speed on ridge racer type 4
cd ~/repositories/cores
git clone https://github.com/libretro/pcsx_rearmed.git
cd pcsx_rearmed
git fetch origin && git reset --hard origin/master
make -f Makefile.libretro -j2 platform=classic_armv7_a7
cp -v *.so $TARGET
