ilidrissiamine has released several new items of interest == How to wii developersport? ==Hi. How do I port games with this? Would I be able to port e.g. SuperTux? What is need and what is to do?Ehhhm, I just read I should use my good old friend google to find out.--[[User:Woku|Woku]] 13:07, 12 January 2009 (UTC)
This project will introduce many ports To port a game, you must first have its source code. Then change the events that use the keyboard or the mouse and replace them with wiimote controls from wiiuse. --[[User:Salehhamadeh|Sal3000]] 11:20, 24 April 2009 (UTC): Someone should write a more thorough tutorial! There's still lots of SDL stuff people could port. --[[User:Tantric|Tantric]] 15:34, 24 April 2009 (UTC):: As someone who just finished re-writing a great portion of SDL games -Wii I think you're a great candidate! ;) Seriously though I would love to see a good tutorial or even just an API reference written. I am madly reading the main SDL tutorial in the hope of figuring out if I can attempt to port the Intellivision emulator jzInTV to the Nintendo Wii and will provide various libraries for , a programme that thankfully already uses SDL. My biggest problem, aside from never using SDL developers that extend before, is emulation of the 12+ button keypad. Anyway bring on a good tutorial / reference it would certainly help me in my quest - if I ever really start it. [[User:Ensign R|Ensign R]] 02:07, 1 May 2009 (UTC)
* SDL_gfx- SDL_gfx port to the Nintendo Wii * SDL_ttf- SDL_ttf port to the Nintendo Wii with its Freetype port * SDL_image.7z Slightly modified SDL_image port to accept various types (libjpeg required) * libjpeg.7z libjpeg port to the Nintendo Wii == __static_initialization_and_destruction_0 error ==
When my program is about to begin linking it gets this error:
File:main.o: In function `__static_initialization_and_destruction_0':
j:/D0g_Engine/source/main.cpp:11: undefined reference to `Timer::Timer()'

j:/D0g_Engine/source/main.cpp:22: undefined reference to `cObjectController::cObjectController()'
j:/D0g_Engine/source/main.cpp:25: undefined reference to `initInput()'
And so on...
Those are So in short, basically every function/class I've defined doesn't appear to exist to the ones are already on linker, this code compiles fine for Windows so is there a setting in the page. makefile or something else I think that the only reason wraggster made that post was because he saw missed to avoid this wiki page. --[[User:Vader347|vader347]] 00:19, 1 August 2008 (CEST)?

== Bad libs order ? Gamecube controller support==
I got It is not documented, but from the following error code it seems that SDL Wii should support also the gamecube controllers which should be mapped to SDL joystick 4-7 (Wii controllers are mapped to 0-3), the stick axes and the pad are associated as in the Wii classsic controller and the buttons are with this order:

== Where's a list of libSDL.a bugs? ==The new warning box at the top of the Wiki page makes it clear that there are There were some serious bugs in the SDL portcode. The Wiki page only lists one bug, and that's in an add-on library. I did a search of the forums, and didn't see anything as serious as a crashNot it is fixed.
Can the author of the new warning or the dev experiencing the crash please provide more details so we can address the issue? I'll take a look if there's something to look at. If there are no crashing bugs, is there another list of functional bugs someplace else I can look at?--[[User:MichaelOibaf|MichaelOibaf]] 16:01, 26 March 2009 28 Oct 2013 (UTC)
