1RPCS3 and iOS
RPCS3 is the PS3 emulator most players already know. Its own project page lists Windows, Linux, macOS and FreeBSD, and iOS is not one of them.
Surume is a separate app built for iPhone and iPad. It plays the PS2, PS3, PS4 and PS Vita games you own, with partial PS1 support.
Note: Surume plays games you own, so bring your own copies.
