Nokia 3310 Simulator -

A Nokia 3310 simulator is a software emulation of the original phone’s hardware and operating system. It runs inside a web browser or as a standalone application, replicating the phone’s 84x48 pixel monochrome LCD screen, the physical button layout, and the proprietary Nokia Series 20 user interface.

: To maintain "3310 accuracy," games often stick to a 15 FPS cap , use only two colors (black/transparent), and avoid sub-pixel movement. nokia 3310 simulator
