While I believe that the current state of Moonlight for the PS Vita is in more than a stable state, it’s nice to know that developers keep working to make it better and better with each release. I had been wondering the last few days if there was more to update and fix in this amazing application and here is my answer: we have minor fixes to stability and support for L2/R2/L3/R3 Buttons on PSTV along with better support for people who use the newest version of the GeForce Experience application, which was recently updated to milestone 3.0.

What is Vita Moonlight?

Moonlight is an open-source implementation of the nVidia GameStream client that allows you to stream your Steam games (and some non-steam ones) to a mobile device of your choice. It allows for high-quality streaming with minimal to no input lag of your PC games. Originally the GameStream system only allowed to stream to nVidia Shield devices, but Moonlight allowed people to stream to their favorite devices and now we can use it on our Vitas too. You can check is your GPU is supported here.

Instructions for Vita Moonlight Alpha 5

For those that weren’t around here is how to customize Moonlight since the Alpha 4 update.

server.txt and config.txt aren’t needed anymore – everything is done from within the app.

Obviously stream configuration only applied after stream restart, input applied instantly.

If you want to use Vita native resolution (960×544) you need to go to NVIDIA control panel => change resolution and add the resolution manually. (Customize=>Create custom resolution) Also, some games might need additional settings to stream 960×544 (for example, for Portal 2 I had to add -width 960 -height 544 command line options).

Default mapping

• LT/LR/LT/RT – back touchscreen
• Pause stream – front-left corner of front touchscreen
• Special key (XBox key, Guide key) – bottom-left corner of front touchscreen

Remapping

Create folder ux0:data/moonlight/mappings and put mappings/vita.conf there, enable Enable mapping file in the settings.
Example: config file with swapped triggers and bumpers: vita.conf

Special buttons on front touchscreen

Check settings. You can also enter key code manually, check this page to find out the right one. Keep in mind that Alt-Tab or Windows key will not work.

Back touchscreen deadzone

Check settings. For easier configuring menu also visualise touches.

Disabling power save

Enabled by default. Vita will not go to sleep when stream is running.
