Ok, here is quick tutorial of playing Back Ups and Imports on your PSONE.
I've also included info on what you need to play PS1 games on your computer.
There are allot of different modchips, and some other equipment for doing this.
Although it just seemed easier to use a PS-X-Change 2
Start the Boot Disc, wait for the message, insert Back Up or Import and press start on the remote.
I have seen this at several sites all ranging between $20 and $30.
Some games will not play since they are Pal instead of NTSC or for a variety of reasons.
Though you could probably play those games on your computer I have found.
Heres what you will need...
1. Get an Emulator, the most current for PS1 games seems to be "ePSXe 1.6.0"
which you can find at http://www.aldostools.com/psxemus.html.
Bookmark this site for later as there are numerous addons at Aldo's site.
Extract the zip file, and make a shortcut for "ePSXeLauncher.exe".
Don't forget to remember the "epsxe160" folders location.
2. You will need PSX Bios "SCPH1001.bin", this may be a little harder to find.
I ran into allot of lost links looking for this, you can most likely find it on a p2p.
Keep in mind to my understanding you must own a Play Station to have this file.
Once you have got the file insert it into the "bios" folder in the "epsxe160" folder.
If it helps, the file I've seen is 512K, the zip is smaller and there may be others.
3. Now you will need the "Plugins", you can get them at
Seems the most current is "gpupete175.zip".
Extract the files and place them into the "plugins" folder in the "epsx160" folder.
4. Now start the shortcut you created for the "ePSXeLauncher.exe" file.
Select the "Config" tab and the "Wizard Guide", this will walk you through the rest.
Keep in mind certain plugins may work better with certain games or other factors.
Right about now you should be saying "playing PS games on a keyboard sucks", I agree.
What you'll need next is a USB to PS Controller adapter.
You can get one at lik-sang and ztnetstore , or at other places for about $15 with shipping.
Although you may find one locally, I found a KiKY at Fry's for $9.99.
There is generally a driver disk to install, though some say they are plug and play with XP.
Install the driver if needed, plug in the remote, then goto the "Wizard Guide" and select the buttons.
Go to the the box of the button you wish to setup and click the same button on the remote.
Now start your shortcut again and...
