86Box vs PPSSPP

86Box is a free emulator for x86-based IBM PC systems and compatibles, covering machines from 1981 through PCI-bus systems. It emulates processors from the 8086 through the Pentium with an emphasis on accuracy and supports configurable machines such as the IBM PC 5150 and IBM PS/2 line. Users can select video adapters, sound cards, network adapters, hard-disk controllers, and SCSI adapters. Supported guest systems include MS-DOS, older Windows releases, OS/2, many Linux distributions, BeOS, and NEXTSTEP. MIDI output can use Windows MIDI support, FluidSynth, or emulated Roland synthesizers. 86Box runs on Windows, Linux, and macOS and is released under the GNU General Public License version 2 or later. The project offers stable and experimental builds; experimental versions may be less stable or slower. Most emulation logic runs in one thread, so results depend on host and guest configuration. A BIOS is required. The project recommends manager applications for multiple virtual machines, while its built-in manager is still a preview.

PPSSPP is a PSP emulator for running games and other software made for the Sony PlayStation Portable. It is available on Android, iOS, Linux, macOS and Windows, with a free plan at free. Games can run at full HD resolution or higher, with texture upscaling and post-processing shaders. Players can use save states and a turbo button, customize touch controls, or connect a controller or keyboard. Save data transferred from a real PSP can continue a game. PPSSPP supports PSP ad hoc and infrastructure multiplayer, including ad hoc play through relay servers, and supports RetroAchievements after account sign-in. It runs PSP software only, not PS1 games or UMD Video discs; users must supply their own PSP game files. Compatibility reports are collected anonymously only when manually enabled. The open-source project is licensed under GPL 2.0 or later. Its official site provides documentation, FAQs, troubleshooting guides and community forums. PPSSPP Gold is available for Android, Windows, macOS and iOS, but not currently for Linux or Steam Deck.
