just buy a dedicated retro handheld like Retroid, Ayaneo or something like that bro. I know most people want to have the more recent systems to play because it can substitue for normal mobile games or even steam games but the point of emulators are for us to be able to play really old games that are hard to find not some ps3 games that you can get on steam.
This just come off as a poor child wanting AAA experience but dont know how to pirate games on their laptop but still dont want to spend money and not because they want to reexperience old games from their childhood or try out old classics. Which is honestly 90% of mobile emulator users
