The record

Product: no$psx is a PlayStation 1/PSone emulator and debugger.
Intended use: The program is intended to work out of the box without special video drivers, plug-ins, virtual CD-ROM drives, a system BIOS, or per-game configurations.
Emulation: The maker says the emulation is intended to implement all hardware features, but notes it has not been tested with many games and may have compatibility problems.
BIOS: The emulator uses a free, faster BIOS clone that may have compatibility issues; the maker suggests placing an original BIOS copy named PSX-BIOS.ROM in the no$psx folder if needed.
Disc and executable formats: It supports CD-ROM images in CCD+IMG, CDI, CUE+BIN, MDS+MDF, CHD, NRG, and ISO formats, plus raw EXE files and ECM/CDZ decompression.
Real CD drives: Reading from real CD-ROM drives is supported and requires wnaspi32.dll; the maker notes this appears problematic on Windows NT/2000 and later.
Development tools: Debugging and development functions include a disassembler, debugger, profiler, code and memory breakpoints, assembler, I/O map viewer, VRAM viewer, polygon viewer, TTY debug console, and PSX hardware specifications.
Performance requirement: The stated minimum requirement is around a 1–2 GHz Pentium 3.
Latest listed release: The download page lists no$psx v2.3, a Windows 32-bit version dated 05 Jun 2026, and a cut-down gaming version.
Graphics update: The v2.3 release notes list pixel-accurate GPU rendering, texture/CLUT cache emulation, and reproduction of average pixel and polygon rendering timings.
Integrations: The v2.3 release notes say i-mode HTTP messages can be redirected to the real internet.
Support: The maker invites bug reports and lists email and no$psx forums as contact options.
Audience: The maker says homebrew programmers have found the debugging functions useful.
Maker: The product page attributes no$psx to Martin Korth; the maker’s donation page identifies Hamburg, Germany in its banking information.
