bro for now we don't have an ps 4 android emulator but there is an emulator named shad PS4 but it's only on pc rn and if you want to run and use that emulator on mobile 💀 you need to have some things such as an pc emulator called Horizon emulator and a snapdragon 8 gen 2 or 3 device and an external cooler but stull if you have all of the things you will only able to play low end PS4 games so it's not worth it
