DOSBox PSP
DOSBox PSP is a DOSBox port for running MS-DOS software on the PlayStation Portable. The project describes it as DOSBox adapted with PSP patches, and credits crazyc with the original port. It supports CUE/BIN disk images, gamepads, audio CDs and Neo Geo CD; save states are not supported. Configuration is stored in dosbox.conf: some settings can be changed through batch files, while others require editing the file. CPU cycle settings are a key factor in performance and may take trial and error to tune. The dynamic CPU core can improve performance for most games, but may reduce stability. Available memory varies by model: the PSP 1000 is limited to around 12 MB, while PSP 2000, 3000 and Go models can allocate about 42 MB by changing memsize; higher settings may cause instability. The initial pre-release build starts at a command line without a file manager, and the project recommends adding a third-party launcher such as LaunchBox for MS-DOS. The project lists a GPL-2.0 license and requires the PSP toolchain to build.
