It might be NES

Often referred to by its short name imbNES, It Might Be NES is an emulator for the Nintendo Entertainment System. It has been designed for PlayStation 1 and 2 consoles. It can perfectly replicate the NES hardware in very small details, meaning users can play some old fashioned NES games on their PS1 and PS2 devices. The last version has been released in 2015, meaning the emulator has probably been abandoned and no further versions will come out.

Its features are quite diversified. It brings in analog stick support and full customization for the controllers. It supports two players at once and allows PAL or NTSC selections. You have SRAM capabilities (save support), as well as an authentic sound and turbo controllers. Users will love the possibility of custom save icons, while the mappers will not disappoint – 0, 1, 2, 3, 4, 7, 9, 11, 34, 66 or 71.
