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: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)?
Ah you are right. Somehow I missed the second download link! Thanks in advance, [[User:CarstenKDoogie|CarstenKDoogie]] 0510:0331, 1 August 2008 3 May 2009 (CESTUTC)
==Example?Cannot compile the template ==
Can someone please write an example of how SDL works I copied the template and all the sdl includes with devkitpro please?Thanks ahead of time!the libs and dependencies into the libogc folder. I tried to compile it using programmers notepad.

-That question was asked on my SDL Tutorial talk page. I also had that error so I reinstalled Devkit with the older SDL version. How do I update Libogc to the SVN version the right way?

LIBS == SDL_Mixer:Mix_PlayMusic playback is very slow = =Hi. I have a strange bug with the SDL_Mixer. When I use the couple of fonction Mix_LoadMUS and Mix_PlayMusic with audio files (Wav or MP3) the SDL lib behaves strangely: All played musics are slowed down and if I whant to get a "good" result I have to increase manualy the pitch of my audio files (+35%)...

== Threads? Gamecube controller support==
This It is a great portnot documented, and I'm sure but from the code it will help porting go a lot smoother for some people.However, there is no threads seems that SDL Wii should support. I did find a way around this also the gamecube controllers which should be mapped to SDL joystick 4-7 (althoughWii controllers are mapped to 0-3), it makes it slower, because no threads) but I would greatly appreciate if someone added thread support to the stick axes and the pad are associated as in the Wii classsic controller and the buttons are with this. It'll make a bunch of ports a lot faster. Thanks --[[User:SquidMan|SquidMan]] 02order:00, 17 December 2008 (UTC)
[[User:Yohanes|Yohanes]] has '''added threads''' and '''USB keyboard''' support to the SDL library while porting [[WiiApple|an apple ][e SDL based emulator]] to the wii.

== sdl-config ==I can not say if the support works since I do not have a gamecube controller to test
It looks like sdl-config needs to be located in bin/ not in lib/. It worked for me after putting it in $DEVKITPPC/bin. The paths in sdl-config seems to be hard-coded "-L/c/dev/apps/devkitPro/libogc/lib/wii" etc - should be dependent on location of libogc and devkitpro.[[User:Oibaf|Oibaf]] 1 Jan 2013 (UTC)
:Right, sdl-config is just a shell script for handling includes, flags, etc more easilynote that you can use the same sdl-config for the PC and Wii with two msys (one for 'PC', one for Devkitpro) and mounting /mingw There were some bugs in each fstab to the path of your libs (- ex :msys PC fstab c:/MinGW /mingwmsys for devkitpro wii : c:/devkitpro/devkitPPC/powerpc-gekko /mingwcode. Not it is fixed.
then only use /mingw into the sdl-config  --[[User:TheDrevOibaf|TheDrevOibaf]] 09:24, 15 April 2009 (UTC) == How to port? ==Hi. How do I port games with this? Would I be able to port e.g. SuperTux?
