Since newer phones have more and more power, why not use that power to emulate old games? Especially classic PlayStation games.
To start, you will need an app called emiPSX, which you can download HERE. The app is free, but you will lack some features of the paid version. Next, you need a ROM of your game you are going to emulate. ROM, or ISO. Best way to do so is to create an ISO from a disc if you have one. Also, a .bin combined with .cue file will also work.
So, the first thing you need to do is get the app. After that, connect your device to your PC. Create a folder on your device, on the internal memory if possible, and copy the game there. Then, open emiPSX. Scroll through and hit internal, or SD Card, depends on where your game is located. Open the folder of your game. You should see the game. To start it, just tap it.
Now… While your Windows Phone device may be powerful, it was never ever meant to run PlayStation games. So, the emulation can be quite slow. But, go into the settings. If you can, play with the settings a little, and that might speed up the emulation. For example, turning off the sound can boost performance.
Some features are only available in the full version, like AutoSave. Also, it’s worth mentioning that the app is not 100% finished, and that you might experience some bugs. Also, with future updates, you might see performance fixes.
