RetroArch serves as a frontend for libretro cores, enabling cross-platform emulation of dozens of legacy gaming systems. On the PS Vita’s ARM Cortex-A9 architecture (with 512MB of RAM), efficiency is paramount. Unlike x86-based PCs, the Vita cannot rely on brute-force computation; it requires optimized, lean emulation.
