The Emulation should be complete with all hardware features fully implemented and working, though as by now it's tested with only a dozen of games, so there may be still some problems with other games (bug reports are welcome).
The BIOS is emulated via a BIOS-clone, which is free and faster than the original PSX-BIOS. There may be still some compatibilty issues (especially as most PSX games are applying patches the to original BIOS; the BIOS clone is reproducing known patches, but may fail on unknown ones). In case of problems, it may be recommended to use a copy of the original BIOS (with filename PSX-BIOS.ROM in no$psx folder).
CDROMs are supported via complete disk images (in .NRG or .CUE+BIN format), via single-track images (.ISO files), or as raw executables (.EXE files). Reading from real CDROM drives is also supported, but does require wnaspi32.dll (which appears to be a problem on WinNT and higher).
Requirements are 1-2GHz, which is maybe not so fast (other PSX emulators are said to be working at 200MHz). CPU emulation is currently done on the fly (I might get that faster by using pre-compiled code in future versions). Rendering is done by software (I could maybe improve speed by adding dual core processor support) (another way would be using hardware acceleration, but my experiences are that this stuff isn't too pixel accurate, if it's working at all).
Debugging/Development functions include disassembler, debugger, breakpoints, assembler, I/O map viewer, VRAM viewer, polygon viewer, TTY console window, and complete PSX hardware specs.
