I am sure I replied but I don't see any reply so here I go again

First of all I want to say I am sorry I might have came across as rude and agressive. The thing is I am very new to steem and your reputation shows 64 so I assumed many people probably read your post and are going to be scammed. Fake emulators like these are very common in emulator world and if someone once installs it is not really possible to remove the malicious code even after app is uninstalled.
You don't have to go to 4th page of Google to check if it is real. A simple google search like 'working ps2 emulators' or something similar will show you this is fake. Read this for basic evidence.

There is only one 'working' emulator of ps2 on android called Play! which barely boots some games.
Also the things which clearly gives of this is fake is that it says it can run every game and even on iOS and it is made from same people who did pcsx2. You can read on pcsx2 site that no such app exists. There are many other instances which shows this is pure bull but I think this should be enough.
Thank you for your time and I am sorry for my bad english not native speaker.
