You might ask: with the Steam Deck, Anbernic devices, and even phones running Neo·Geo games via MAME4droid, why chase an old PSP emulator from 2010?
Three reasons:
Homebrew communities like Reddit’s r/PSP and GBAtemp continue to share updated ROM packs and cache sets specifically for MVSPSP 2.3.5. In many ways, this emulator defines the “gold standard” for single-purpose retro handheld emulation. mvspsp 2.3.5
This paper provides a technical analysis of MVSPSP version 2.3.5, 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.
While MVSPSP 2.3.5 was a marvel of optimization, it had specific constraints: You might ask: with the Steam Deck, Anbernic
These sibling emulators (same developer) handle Capcom arcade games. 2.3.5 can run some CPS games, but the dedicated emulators are better for Street Fighter and Final Fight.
Let’s break down what makes this specific version so beloved. This paper provides a technical analysis of MVSPSP
Unlike PPSSPP’s universal settings, MVSPSP 2.3.5 includes hardcoded toggles for specific titles:
