PlayStation Relocatable Executable (PRX) is a variant of the Executable and Linkable Format (ELF) developed by Sony Interactive Entertainment for its gaming consoles. This format primarily serves as a dynamic link library or system module for the PlayStation Portable and PlayStation 3 platforms, supporting system-level drivers and custom plugins. Although largely considered a legacy format today, these files are generally safe to store but require specific hardware or emulated environments to execute their intended functions properly.
