wtf is pokketstation?

pokketstation is an open source recreation of the Sony PocketStation, a small handheld accessory from the late 1990s that plugged into the original PlayStation's memory card slot and could run its own tiny games and act as a memory card at the same time. This project is not a game itself, it is an emulator core, meaning it is the piece of software that faithfully mimics the PocketStation's internal hardware so that real, original PocketStation software can run inside a modern computer or device as if it were running on the genuine hardware. The core is written in plain, portable C, and it is deliberately kept separate from any particular user interface. This lets the same core power three different ways of using it: a standalone desktop application for Windows, Linux, or macOS, a plugin core for the popular RetroArch emulator front end, and a homebrew port for the PS Vita handheld. According to the project, the emulator has been tested extensively with a real PocketStation game and a real original BIOS dump, running for hundreds of millions of simulated instructions without hitting anything it could not properly emulate, and its author keeps detailed public notes describing exactly which hardware behaviors have been checked against the real device and which remaining edge cases are still simplified. To actually use it, a person must supply their own copy of the original PocketStation firmware, called a BIOS dump, since the copyrighted firmware cannot legally be included with the project itself. From there, the desktop version or RetroArch core can load either a full memory card image or a single saved game file, and the emulator can be controlled with a keyboard or a standard game controller depending on which version is used. Building the project from source requires standard C and C++ development tools such as CMake, and on Windows specifically it requires Visual Studio's build tools and a package manager called vcpkg for the desktop application's graphical interface. This project is best suited for retro gaming enthusiasts, emulator developers, and people preserving old hardware and software, and it assumes some comfort with command line tools, since actually running it depends on legally obtaining your own copy of the original device's firmware.
