Gamma, a free emulator that allows users to play games from the original PlayStation One, has been added to both the Apple App Store, which it can download for use on iPhone and iPad

Gamma is similar to the recently released Delta emulator, especially in terms of its interface With this app, users can customize the controller skin on the screen and support Bluetooth controller and wired keyboard The emulator uses both Google Drive and Dropbox for backing up disk images and saved progress; users can choose their preferred service in both game backup and save stages

The purpose of the emulator is to allow users to write already purchased games from the disc into a software called Rom It allows people to play PS1 games on the go, something Sony has tried in the past with PS Vita But problems can arise with emulators - that is, people can download them and play them without buying games, free

So the emulator itself is not illegal, but it is certain to download and run copyrighted games Some retro games have fallen into the public domain, but in other cases, companies actively protect their old titles Take Nintendo, which is well known for protecting its copyright

For a long time, Apple avoided adding emulators to the store, even if it was an app widely available on Google's Play Store for android users However, Apple changed its store guidelines on May 4, as regulatory pressures are mounting in both antitrust lawsuits in the EU and the US
