PCSX v1.6 no longer has a specific recommended bios number, so it'd be wise to use a more modern bios, read on.

Run the emulator without one at first, to receive instructions where to place the bios file (v1.5 recommends model 1000 and its file to be installed in ~/Library/Application Support/Pcsx/bios/ ). The third download has several versions of the PS1 bios, which the emulator requires one. Spyro does not freeze when played via Mooby mode. Game 'Spyro The Dragon' experiences lockups using CD-ROM Device mode, like simply by pressing the Select button repeatedly (mapped to the key by default). 'Mooby mode' may possess greater emulation compatibility. 'Mooby mode' works cleaner and can be added to the 2005 app by copying in the 2006 app's Contents/PlugIns/cdrmooby.psxplugin file. But 2006 tries to autoeject when quitting and messes up by ejecting the desktop icon without ejecting the actual image that Toast mounted (use diskutil to complete eject). toast image files of PS1 gamediscs mounted using Toast and then play them. To do this, go to Preferences > Plugins and choose the 'Mooby cd disk image driver' and never alter prefs with a game running, close any running game first. 2006 can play iso/toast image FILES without having to mount them first. Higher v1.6 is more accurate emulating than v1.5 for example the game Kingsley's Adventure had tons of bad graphics but not in v1.6. There are two versions, first dL is more recent v1.6.0 (aka 2006) and the second dL is a beta version ('1.5.0 test 3' aka 2005). (For Intel Macs, see PCSXR.) Our Macintosh apps were ported from PC hence the name this was given 'pCsx'. OS X for PowerPC has this PlayStation 1 emulator that is free and open source.
