Compatibility and Purpose The core appeal of running PSX software on a PSP lies in portability and nostalgia. A PSP-targeted PSX binary aims to recreate classic PlayStation games on a handheld device designed a generation later. If "psxonpsp660bin" refers to a specific build (for example, a version optimized for 6.60 firmware or a build that targets certain PSP hardware), its perceived superiority depends on how well it addresses compatibility, performance, and usability compared with alternatives.
