no$psx vs WiiSX

no$psx is freeware for Windows that emulates and debugs PlayStation 1 and PSone software. It is intended to run without special video drivers, plug-ins, virtual CD-ROM drives, a system BIOS, or per-game configuration. Supported disc images include CCD+IMG, CDI, CUE+BIN, MDS+MDF, CHD, NRG, and ISO, alongside raw EXE files and ECM/CDZ decompression. Real CD-ROM drives require wnaspi32.dll, with the maker noting problems on Windows NT/2000 and later. Development tools include a disassembler, debugger, profiler, code and memory breakpoints, assembler, I/O map viewer, VRAM viewer, polygon viewer, TTY console, and PSX hardware specifications. The free BIOS clone may have compatibility issues; an original PSX-BIOS.ROM can be placed in the program folder. The maker says many games have not been tested and compatibility problems may occur. The listed v2.3 Windows 32-bit release adds pixel-accurate GPU rendering, texture/CLUT cache emulation, and timing reproduction. The plan price is free.
