{{#seo: |title=Vita Homebrew Apps (Plugins) - GameBrew |title_mode=append |image=dsmotionvita2.png |image_alt=DSMotion }} DSMotion is a HENkaku plugin which adds motion control support for PlayStation TV with DualShock controllers. It can also be used on a real PS Vita with [[Ds3vita|ds3vita]] or [[Ds4vita|ds4vita]] plugins to replace the console internal motion sensors by those from the controller (however, it doesn't work well with ds3vita, see limitations section). 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 features, you must edit your ux0:tai/config.txt (or ur0 if you store the plugin there) *KERNEL ux0:tai/dsmotion.skprx *TITLEID00 ux0:tai/dsmotion.suprx Replace *TITLEID00 by a title identifier which needs motion control or by *ALL to affect all titles. ==User guide== === 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. * PCSB00360 - Rayman Legends - Murfy can now perform actions which requires motion control. * PCSB00031 - Virtua Tennis 4 - "Match VR" mode could feel it has inverted horizontal controls (read limitations). * PCSF00024 - Gravity Rush - "No gravity" mode could feel it inverted horizontal controls (read limitations). === 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 [[Ds3vita|ds3vita]] 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). * Computed orientation is wrong when the controller is turned upside down (it could happen in a game when you try to look too verticaly high). * Currently, gyroscope data is not exploited during orientation compute (due to drift problems I had when I tried), feel free to give help if you have some maths/IMU skills. * Some games could be perceived like they have inverted horizontal controls (specially during FPS and TPS viewpoints) but it is a wrong impression (on a real PS Vita, tilting the device on the left also makes the view goes to the right and vice versa). ==Changelog== '''v1.2''' User plugin changes: *Partially fix device orientation computation: highly improve camera stability and fix some inverted axis issues. Documentation changes: *New limitation discovered: don't turn your controller upside down or the orientation computation will go wrong. *Explanation about some perceived inverted axis issues: please try to test the game behavior on a real PS Vita before reporting issues on this subject. '''v1.1''' 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 control issues. '''v1.0''' * First Release. ==Credits == * xerpi for his [[Ds3vita|ds3vita]] and [[Ds4vita|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 Vita|HENkaku]] which makes everything possible (except coffee) on this device. == External links == * GitHub - https://github.com/OperationNT414C/DSMotion * Wololo - https://wololo.net/talk/viewtopic.php?f=116&t=48407 * VitaDB - https://vitadb.rinnegatamante.it/#/info/298
