DOSBox PSP vs MS-DOS Player

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.

MS-DOS Player is a free command-line emulator for running 16-bit DOS-compatible commands in a Win32-x64 environment. It is aimed at text-mode utilities such as file converters, compilers, assemblers, debuggers and text editors. DOS programs inherit Windows environment variables and can access host file paths directly. The Windows archive provides binaries for emulating 8086, 80286, 80386, 80486, Pentium 4, NEC V30 and IA32 processors. Documented hardware includes up to 32 MB of RAM, LIM EMS, serial and parallel I/O, keyboard and mouse input, timers and text display. Virtual COM1–COM4 can connect to host COM ports, with a maximum baud rate of 9600 bps; parallel output is written to a timestamped .PRN file in TEMP. A 16-bit command file can also be embedded in a 32-bit or 64-bit executable that runs without msdos.exe. The project is a fork tuned for the ReC98 build process, and its source is available under GNU General Public License version 2.
