This paper provides a technical analysis of , a specific iteration of the Multiple Video System PlayStation Portable (MVSPSP) emulator. Developed during the peak of the homebrew movement for the Sony PlayStation Portable, this software represented a significant achievement in efficient code optimization. It allowed the handheld hardware—limited by a 333 MHz processor and 32MB/64MB of RAM—to faithfully replicate the SNK Neo Geo MVS/AES arcade hardware. This document details the architectural requirements, the significance of version 2.3.5 within the homebrew lineage, and the technical challenges of high-fidelity emulation on constrained embedded systems.
