Mac OS X Snow Leopard PlayStation Emulator, PCSX-Reloaded





Introduction: Mac OS X Snow Leopard PlayStation Emulator, PCSX-Reloaded

Hello there,
A while back I released an instructable on getting PCSX up and running in Snow Leopard, I have since found a more stable/ and quite frankly all round better program, PCSX-Reloaded. In my case, it has been alot more reliable and easier to use with still more features. So here is a tutorial on getting PCSX-Reloaded up and running :)

QUICK NOTE: If you followed my previous instructable about installing PCSX, before you begin this, drag your current PCSX from your applications to the trash and empty.

Step 1: Files

So then, we begin by downloading our necessary files:

That's our necessary files.

Download from this link ( or from the file uploaded with this step.

Download PSX BIOS from this link ( or from the file uploaded with this step.

Step 2: Installation

Now, if you haven't already, go ahead and unzip, inside is the application.

Now drag the 'PCSX' file into your applications folder.

(If you followed my previous instructable go on to the next step here)

Next, if you haven't also already, unzip PSX BIOS and there is a folder with the BIOS you need. Now select all the files inside that folder (Picture 1) And put them inside this folder.
>> YOUR USERNAME (e.g. spikematthewspadley)
>> Library
>> Application Support
>> Pcsx
>> Bios

So your result should be something like Picture 2.

Step 3: Configure

Now, go into your applications folder and open up PCSX!

You'll want to change the settings in your preferences so they look like mine, in picture 2.

I also recommend that from that menu you select "Plugins" and configure your keyboard.

Step 4: Finished!

And you're done, that was easy.
Now you can run BIOS, Play games from CDs and load from ISOs

When I to run ios a window opens saying, "The operation couldn’t be completed. Error Opening GPU Plugin"... What do I do? please help.

A second question I have, is... I have Fpse for Android, I have a few roms on my phone for it, is there a way to have the same roms for my phone on my computer, and also be able to transfer the save file too and from my phone and computer?? That way I can play a game, ex. Silent Hill, while I'm out and then what progress I made while I was out I can then continue on my computer when I get home. Is that possible?? If not it's cool, just curious.

Is there a way to use cheat codes?? Like Gameshark or Gamegenie codes?? I really enjoy these PS1 games, and I have a few ISO Roms to play as well as the disks them-selfs. But, at least for the ISO files, is there a way to use cheat/s codes?? Thank you.

Hey man, I'm running 10.6.8 Mac OS X Snow Leopard, plenty of drive space and memory. I used this program before [the older version], and it worked great. I love being able to play Metal Gear Solid on this thing, however I am unable to beat the part that requires the user to plug the controller from port one to port two lol. Is there any way to do this?
My other question was the last version couldn't play the original Resident Evil, can this version play it? All of my games are original PS1 CD Roms.

Thanks so much man, this is an awesome emulator to play old games without having to re-buy the platform.

This may sound completely stupid, but PCSX isn't opening when I launch it... I've doubled check everything and I have done everything right up until now... help?

can i customize controls in pcsx-reloaded? I can find the preferences.

I'm a noob at this.

I just put this emulator on my brand new MacBook pro. I've used emulators for systems like NES and SNES, but I'm told using a Playstation one is more complex. I found a place to download PS games, but I'm told I need to have iso's to play them on the emulator or something? And they need to be done some special way to make the machine think they're cd's?

I downloaded one PS game. It was a .rar file, which opened into one .cue file and one .bin.ecm file. I don't know what to do with them.
In case you hadn't guessed, I have no idea what I'm doing at this point. Any help is appreciated.


I keep on getting ERROR OPENING GPU PLUGIN :( i wna play monster rancher 2 but i cant!!! pls hep me :(

Having some trouble. Did everything instructed but every time I open up an ISO rom I am prompted that there was an 'Error Opening GPU Plugin'. Can anybody offer some help with this please?

For anybody still having trouble with this step, remember that these files need to go into your Pcsx folder in your USER Library, not HD Library. By default, Lion's User Libraries are hidden. Here are steps how to bypass this:

I tried opening an iso and it says "could not check cd-rom". I know others are having this problem, but no one has yet to post an answer. Could someone help me out with this?? Thanks.

I found out how to play them, got my FF8 going.
1. Just get a program called UnRarX, from (only takes a couple of seconds to download).
2. open it up and select 'browse' button in top right corner, then pick your game or .rar file.
3. Press 'extract' button, also in top right corner.
4. Once it has extracted, run PCSX> choose run iso and pick the game, all should be good. Game file should now look like a zip file rather than a blank piece of paper.

Hope this helps, i just got lucky with finding this i think.

Game won't show up on Desktop...
I have tried every single game I have, and they all won't show up on the desktop. It also gives me the same warning telling me that it cannot run please!

Yeah I used "The Unarchiver" app to basically do the same. I finally have mine working now, and I'm so happy lol. Thanks for the advice anyway, and it'll probably help others that are having the same problem.


had a huge issue with this myself, it's hidden folder on Lion now :( so easy though, hold option and click go, library will be there.

sorry about double post, it wouldn't let me delete the other and I mistyped.


had a huge issue with this myself, it's hidden folder on Lion now :( so easy though, hold command and click go, library will be there.

I also have the same problem as odoylerules2011.
Downloaded the first disc of FF8, it's a .rar file though, but get the same message when i try to load it. Does it need to be converted or something.
