PlayStation TV (PSTV) user's got a new plugin DSMotion (two variants available) which aims to add Motion Control Support for both the DualShock 3 k 4 controllers, which is essential in completing / playing some games as these games were blacklisted from playing the PSTV originally. There are some limitations but a step forward especially for games that require some motion controls as the titles outlined in the release note.

DSMotion
Henkaku plugins which adds motion control support for PlayStation TV with DualShock controllers
There are 2 plugins:
- Kernel plugin dsmotion.skprx: it hooks BlueTooth calls to catch DualShock controller packets and exposes user services to get the intercepted motion data
- User plugin dsmotion.suprx: it calls the kernel plugin services and reinterprets the given data for SceMotion functions return
Installation
In order to activate those plugins featues, you must edit your ux0:tai/config.txt file:
Replace TITLEID00 by a title identifier which needs motion control or by ALL to affect all titles.
Compatibility
- NPXS10007 - Welcome Park - The skate board game is playable.
- PCSF00214 - Tearaway - Introduction which asks to shake the PS Vita can now be passed by shaking the controller.
- PCSF00349 - Flower - The game is playable.
- PCSF00007 - WipEout 2048 - The game can be played with motion commands option.
- PCSA00029 - Uncharted Golden Abyss - River game at chapter 12 and other balance mini-games can be completed.
- PCSB00031 - Virtua Tennis 4 - "Match VR" mode has inverted horizontal controls.
- PCSF00024 - Gravity Rush - "No gravity" mode has inverted horizontal controls.
Limitations
- If a DualShock 3 controller is used, it must not be directly plugged with USB on the PS TV otherwise, signal will be sent through USB instead of BlueTooth (and it won't be catched): use an external charger for the controller.
- It doesn't work well on classic PS Vita with "ds4vita": for an unknown reason, motion control samples seems to be too much spaced over time.
- It hooks documented "SceMotion" user functions instead of undocumented "SceMotionDev" kernel functions: if we could understand those kernel functions, we could have more compatibility with a single kernel plugin (no more need for a user plugin).
- Device orientation quaternion and rotation matrix are not currently accurate: they give unstable result and they don't support full orientation, feel free to give help if you have some maths/IMU skills!
- Some games (specially those with inverted horizontal controls) call functions to activate the PS Vita magnetometer: DualShock controllers don't have this feature.
Credits
- xerpi for his "ds3vita" and "ds4vita" plugins source code which helped me a lot to understand BlueTooth communication!
- TheFlow for his "VitaShell" source code which helped me to understand how to export functions from kernel plugin and call them in user plugin
- YifanLu for Henkaku which makes everything possible (except coffee) on this device!
Update: Version 1.1
Vertical control issue fix
User plugin changes:
- Change cross product way for device quaternion to fix some vertical inversion
- Remove useless hook on "sceMotionGetBasicOrientation": this function always returns (0,1,0) even on PS Vita
Documentation changes:
- Compatibility list updated (special thanks to "stranno" who made a lot of tests!)
- Limitation on signed titles removed: after some tests on original titles, it works fine
- New limitation discovered: apparently, PS Vita can activate a magnometer which is used specially by games with horizontal conrol issues
