open8 is a PICO-8 emulator written in C99 and currently under active development. Built with portability as a primary goal, it is designed to run on a wide variety of platforms, including devices such as the Nokia N-Gage. In principle, any system supported by SDL3 (Simple DirectMedia Layer 3) should be able to run open8.
There are already several excellent PICO-8 emulators available, including fake-08, pemsa and retro8. Each of these projects serves its own purpose and has contributed significantly to the community.
However, most existing emulators are written in modern C++, which can present challenges when targeting older hardware and operating systems. These platforms often have limited compiler support and may struggle with newer language features.
open8 takes a different approach by using C99, prioritizing portability and compatibility across a broad range of systems. This focus makes it particularly well-suited for the retro homebrew community, where support for legacy hardware is often a key requirement. By keeping the codebase in C, open8 aims to remain accessible, lightweight, and easy to port to unconventional or resource-constrained platforms.
