What psxe is

psxe is a portable Sony PlayStation emulator and emulation library written in C. The project lists CPU, DMA, GPU, SPU, MDEC, GTE, timers, and CDROM among its implemented components. Running the emulator requires a BIOS file, which users configure with the -b or --bios setting; the README says most BIOS versions are confirmed to work. The project is free and open source under the MIT license. GitHub Releases provides automated builds, and the README includes instructions for building from source on Windows, Ubuntu, and macOS if a system is unsupported by an available build. SDL2 is needed for building. Platform-specific setup also applies: Windows standalone use requires the SDL2 DLL beside the executable, Ubuntu instructions call for libsdl2-dev, and macOS setup uses SDL2 and dylibbundler, which the README says can be installed with Homebrew. Memory card support is temporarily disabled. The releases page lists PSXE 0.10.5-alpha as the latest release, with a note that the version number was updated after a long period of inactivity. The GitHub profile identifies the maker, allkern, as Lisandro Alarcón, an Argentine computer science student.
