I downloaded and extracted the files and got .ccd/.img/.sub. none of these do anything! pcsx doesn't even seem to acknowledge that I'm attempting to run them. if anyone knows how to get the files to run I'd greatly appreciate the info

Hi. PCSX doesnt say its mac compatible so you may come across some problems.
those are the correct file formats and they work on PC.

if its not working i suggest you try our recomended emulator ePSXe as it may very well work on MAC better then PCSX.

http://www.epsxe.com/files/epsxe170.zip

you also need video plugins, i recomend petes plugins.
this is the zip you need: http://www.pbernert.com/gpupete177.zip
extract that to the plugins folder in your epsxe folder

i have uploaded the bios for here: http://www.filefactory.com/file/a2c6aec/n/PSX_BIOS_SCPH1001_zip
extract that to the bios folder in your epsxe folder

you may also need this dll to get epsxe working properly, i did: http://www.filefactory.com/file/affgb2f/n/zlib1_zip
extract it to your epsxe folder

run epsxe, if you havnt done it run the setup wizard, it will either start when you start the program or you can find it under config, wizard guide.
the bios file should be on the list as scph1001 so selct that. select petes dx6 d3d driver, then just click next till your done. (change the controller settings if you want)

remember that alot of emulator coders code for PC so dont expect any to work 100% on MAC unless they state otherwise.

try that and if not get back to us and i'll see if one of the MAC users can help.
