I play ff8 playstation version on pc, with ePSXe emulator. How can I use..

I don't think playstation games can be played on a pc. You have to get the pc version of 8 which you need to try ebay.

>I don't think playstation games can be played on a pc.
Ps games can be played on pc, just need an emulator, and it works fine..

You cannot use playstation gameshark devices on pc. You would need to get the pc game and use a pc gameshark device. Besides, all emulators that I know of are usually illegal so I do not think that it would be a good idea to play playstation games on pc.

Dude those 'boosters' to play counterfeited games(playstation 2) or altering formats(ps1) are illegal so I don't recommend getting one and chances are you will get caught.

I'm not sure myself, I'm also looking up how to figure this out. Btw emulators aren't illegal, the copyrighted BIOS software of the emulated device usually is. Which is why nobody offers emulators with the BIOS in them. Only pirates do. If you however own a ps1-2-etc. Uploading the BIOS from that isnt too hard and is perfectly legal. I should know, I still own my original playstation and all my games on disc, but prefer to use my comp ter to play. Its better faster and has graphic enhancement plugins. And playing is as easy as popping the disc in my computer and viola. Going back on topic, I believe it has to do with the cheats folder and a text document put in a specific format with the identifier for the game your going to use it on In the title and the cheats listed properly within. I'm still trying to figure it out.

If you are using this (ePSXe emulator),I recommend the following application.
(PEC) Play station Emulator Cheat. Download from the web and install, follow the instruction, not forget to put on the folder (PLUGIN). Once you finish you will see an icon on the desktop. Click on them and you will see a list of game, depends on the region you can chose (USA , CANADA, JAPAN) versions, you can check some videos on how to install and using.
