If you are willing to create a branch of Abbaye which calls SDL_SetWindowDisplayMode to set the video mode, then it will be easier for me to add the missing support.

Apologies dude, I didn't notice you requested this until now. I made a branch here: https://github.com/JeffRuLz/abbayedesmorts-3ds/tree/wii

First of all, I made it so it sets the display mode to 320x240 if it detects a file called 240p.txt (here). I'm not really sure if I did that correctly.
Also, setting SDL_WII_JOYSTICK_SIDEWAYS doesn't seem to change anything. The d-pad is still oriented like the remote is upright. It's set before SDL_Init so I'm not sure what I'm doing wrong there.

And lastly, since this game runs at 256x192 I wanted to display it in the center of the screen with a border filling the remaining space. When the window size doesn't match the logical size then the game is displayed in the top left corner. I believe the standard SDL behavior is to center the screen to the window, but I may be remembering wrong.

Well, any SDL2 samples should work. As for games, I personally ported these two:

- https://github.com/mardy/VVVVVV/
- https://github.com/mardy/oceanpop/tree/wii-port

Thansk!
After a bit of looking, I tried porting Sonic Robo Blast 2 to the Wii since it uses SDL and has a Software Renderer, but it's refusing to boot, seems to be failing at SYS_Init, do you have any idea what could be happenning?
My current work is at the Github Repo Fancy2209/SRB2

Also, I (succesfully this time) ported Sonic Robo Blast 2.1.25 to the Wii, but the Joystick api reports there are 0 Joysticks avaliable, this prevents me from using any kind of controller, Wii Remote, Classic Controller or GameCube Controller.
Any ideas? It's not that great to need to plug a keyboard in.

The problem is that joysticks take some time to appear. You can either change to the polling API, or add this at the beginning of the game (after SDL_init()):


    while (SDL_NumJoysticks() == 0) {
        SDL_PumpEvents();
    }

Hello !
I'm a french computer science teacher triing to make my pupils code some retro games on the wii. Since this year I was using GRRLIB for graphics and asndlib for the sound. Found that sound library was not so good (only 1 sound at a time) and was seeking for other solutions. Then I saw that SDL2 was available in pacman for the wii and wanted to give it a try.

So i tried to compile an exemple (SudokuL) but I went into the "undefined reference to `SDL_main'" error.

steps :
Installing SDL2, SDL2_mixer, SDL2_ttf ... from pacman
downloading SudokuL sources and unzipping
renaming makefile_wii to Makefile
launching make then

/opt/devkitpro/devkitPPC/bin/../lib/gcc/powerpc-eabi/13.2.0/../../../../powerpc-eabi/bin/ld: /opt/devkitpro/portlibs/wii/lib/libSDL2main.a(SDL_wii_main.o): in function `main':
/home/davem/projects/devkitpro/pacman-packages/wii/SDL2/src/SDL2-2.28.5/_build/../src/main/wii/SDL_wii_main.c:86:(.text.startup.main+0xcc): undefined reference to `SDL_main'
collect2: error: ld returned 1 exit status

What am I doing Wrong ?

Thanks in advance :-)

You have to also move the makefile up a directory into SuDokuLVS2019. I put the makefiles in their own subdirectory a while back and forgot to update the readme accordingly; sorry about that!

The game doesn't seem to call SDL_Init() in the way you expec as this is not working, and I don't want to rewrite SRB2's Gamepad Handling for the Polling API
