Note from Wololo: This tutorial was initially published by /Talk member sindromedo, as part of our monthly tutorial contest. Sindromedo won the best PS Vita tutorial prize (a $10 PSN Code) for his entry. You can find the original post here.

In this tutorial I teach you how to create your own applications for PS VITA with PlayStation Mobile Studio (PSM Studio).

First, you have to download the PSM Studio from this page: https://psm.playstation.net/static/general/all/en/psm_sdk.html **( you need to register,but don’t worry, you only need a PSN account and an email address)**

After download and install, enter in this page from your PS VITA: https://psm.playstation.net/static/general/all/devassistant.html and download the PSM Dev Assistant for PS VITA.

Well, it’s time to do our first program: The Hello World.
First, open the PSM Studio and go to New–>Solution. After that select C#–>PlayStation Mobile–>PlayStation Mobile Application.

Now in the top bar select Visual Design.

Now we have a new bar in the left side. In this new bar do right click in References and select “Sce.PlayStation.HighLevel.UI” and click OK.

The final step is select with double click “Appmain.cs”…

and delete the code that’s there and copy this new code:

using System;
using System.Collections.Generic;

using Sce.PlayStation.Core;
using Sce.PlayStation.Core.Environment;
using Sce.PlayStation.Core.Graphics;
using Sce.PlayStation.Core.Input;
using Sce.PlayStation.HighLevel.UI; 

namespace UIToolkitApp 
{ 
    public class AppMain 
    { 
        private static GraphicsContext graphics; 


        public static void Main (string<> args) 
        { 
            Initialize (); 


            while (true) { 
                SystemEvents.CheckEvents (); 
                Update (); 
                Render (); 
            } 
        } 
 public static void Initialize () 
        { 
            // Set up the graphics system 
            graphics = new GraphicsContext (); 


            // Initialize UI Toolkit 
            UISystem.Initialize(graphics); 


            // Create scene 
            Scene scene = new Sce.PlayStation.HighLevel.UI.Scene(); 
            Label label = new Label(); 
            label.X = 10.0f; 
            label.Y = 50.0f; 
            label.Text = "Hello World!"; 
            scene.RootWidget.AddChildLast(label); 
            // Set scene 
            UISystem.SetScene(scene, null); 
        } 


        public static void Update () 
        { 
            // Query gamepad for current state 
            var gamePadData = GamePad.GetData (0); 


            // Query touch for current state 
            List touchDataList = Touch.GetData (0); 


            // Update UI Toolkit 
            UISystem.Update(touchDataList); 
        } 


        public static void Render () 
        { 
            // Clear the screen 
            graphics.SetClearColor (0.0f, 0.0f, 0.0f, 0.0f); 
            graphics.Clear (); 


            // Render UI Toolkit 
            UISystem.Render (); 


            // Present the screen 
            graphics.SwapBuffers (); 
        } 
    } 
}

And congratulations, you do your first program for the PS VITA . To test the code just press F5 or connect your PS VITA with CMA and select “PS VITA” in the top bar (you have to open the PSM Dev Assistant in your PS VITA. See how to pack your app below)

You get something like this:

GETTING A PSM LICENSE

If you want publish your app, you need a PSM license. This is the most easy step, but you have to pay for the liscense.
First, after log in in the PSM web, click the button that says “Apply for PSM license”.

Next fill in the required fields and wait for the data to be processed (approximately 4-5 days).
Once you get the confirmation email, go back to the page and look at the same area (marked in red in the photo) and click on “purchase publisher license” to complete the purchase and you’re all finished.

PACK YOUR APPS TO TEST/RELEASE

To test / release your app, you need make a license for your app.
For this, start Publishing Utility and PSM Studio. After, select the XML of the app with right click and select edit with Utility Publisher.

Now connect your PS VITA to your computer.
You will start in the Metadata section. The data can be left unchanged if you want, but is needed data like the icon, the app ID, the rating, etc.
If you finish click on the “Save” button to save your entries to an XML file.

Now, go to Key Management and create a new Key for your app.
The program will ask your PSN account to verify your publisher license

Your PS VITA has a unique ID associated with it that will be used in making the key that is used to sign the code. The device should automatically be recognized (if you have your ps vita connected to your computer) . Click on the button with the key ring icon to add a new application and that’s it !!!
