– Benchmarks performed by the project’s CI using a PSP‑Slim (model 2000) with a fresh 6.60 firmware and a fully charged battery. Results represent average FPS over a 2‑minute window after the game reaches the main gameplay loop.

There is a community of developers and enthusiasts who create custom firmware (CFW) for the PSP. Custom firmware can enable additional features not present in the official firmware, such as better performance, new user interfaces, or the ability to run homebrew applications. psxonpsp660.bin github

The file is a PlayStation (PSX) BIOS file originally included in Sony's PSP firmware version 6.60 . Unlike traditional PSX hardware BIOS files (like scph1001.bin ), this version is highly sought after in emulation circles because it is an "omni-BIOS"— region-free and optimized by Sony for better performance and compatibility. – Benchmarks performed by the project’s CI using

– psxonpsp660.bin is a custom‑firmware (CFW) binary for the PlayStation Portable (PSP) that enables the PSX‑on‑PSP home‑brew environment on firmware 6.60. It is maintained in the psxonpsp GitHub repository, is open‑source under the GPL‑2.0 license, and is the most up‑to‑date, community‑tested release for PSP 6.60 devices. The binary works by patching the system’s kernel at boot, loading a small loader that then runs the PSX‑on‑PSP emulator (the psxemu core) and a collection of front‑ends for ISO mounting, cheat handling, and controller mapping.
