DigitaOS

DigitaOS is a operating system for digital cameras made by Flashpoint Technology. The first device to use it is the Kodak DC220, released on . It was known for being able to run third party software, which was not common until ones running Android came out in the early 2010s.
Programs can be written in a scripting language named Digita Script, which is JIT compiled, or compiled, written in C using an official SDK. Abstraction is used so programs can run on most cameras, despite any camera model differences. DigitaOS runs the GUI and basic camera functionality.
Doom and MAME are the best known ports.
