From what I can tell, IR is not yet available to Homebrew development. However, it would be nice to make that a reality! Nope, never mind. Basic functions (an soon more complicated functions) are now available! Here are some resources I have found regarding the IR port for the o3DS: IR_Services - The 3Dbrew list of Infra Red related services (includes irrst, or the service relating to the c stick of the n3DS). smea's ir.c and its header - C tools used to interface with IR. Don't seem to currently work. IR:rst - Tools used to interface with the C stick (currently works, I assume, but I have an o3ds...). A test I made from a fork of CTurt's 3DS Controller in attempt to init and use the IR port. (Gives error d8e06406 on initialization). Another test specifically to cover inputs for the 3ds. TRY THIS ONE AND REPORT YOUR FINDINGS. Has compiled binaries and an icon. (I will add any other resources found by others to here) From what I have searched, it appears that IR and the CPP don't have a place to call home, so here it is! If there is any information you have on IR, please post it here (I would really like to see peoples CPP work with homebrew!). (Hopefully this is more constructive than that eShop sales editor thread... but if I broke a rule please tell me, as this is my first post here.) BIG IMPORTANT EDIT: Users are currently checking IR availability using this program. Check the quoted post for details. Updates on model/version/*hax will be posted below. Tested: @RedHat o3DSXL,, 10.1.0-27U using Tubehax+ Browserhax --WORKS WITH OoT! @RedHat 2DS, 9.6.0-24U using Tubehax + Browserhax @Pandaxclone2 o3DS XL, 9.5.0-22E using Themehax + Browserhax --WORKS WITH OoT! @VegaRoXas 2DS, 7.1 using Ninjahax on Sysnand --WORKS WITH OoT! @Megalegacy98 2DS, 10.1 using Ironhax/Tubehax/Themehax (I assume others have had OoT work as well) SUPER ULTRA BIG EDIT!: In order to use IR, the homebrew that uses IR MUST be launched with the following apps: Cubic Ninja (US and EUR) Ocarina of Time 3D Toki no Ocarina 3D (OoT 3D) Dead or Alive Dimensions. If "select an app" does not appear when starting a homebrew that uses IR, please check to make sure your .xml file is configured correctly. It should be called (name of homebrew).xml and have this inside: Code: <targets selectable="true"> </targets> Thanks to: @VegaRoXas @SomeGamer @Pandaxclone2 @daxtsu @Megalegacy98 @the assaf AND ANY OTHERS FOR ONGOING DEVELOPMENT!
