Some news :
Before releasing Mod 4, I'll be focused on fixing Rayman DS. The game works, but instead of the "press start" screen, there's a black screen, and when I press Start, the game does strange things, like overwriting data at some memory locations. For the black screen, I noticed that the game sends data to the 3D core and all of these data seem valid, except the vertex coordinates that are always zero (don't know why, it needs more debugging).
Anyway, I've fixed one of the big bugs of Mario Party : the players were "not fully visible", even almost invisible. After doing some logging, I noticed that the game was changing material colors for each vertex. I thought that it wasn't allowed in OpenGL. While searching a way to do this, I found the official description page for glMaterial. I read there that OpenGL allows, just like the DS, to call glMaterial between glBegin and glEnd in order to set a material color per vertex.
The bug was that the 3D core was stopping and resuming vertex list at each glMaterial call. Try drawing some geometry with OpenGL, and calling glEnd and glBegin between each vertex. OpenGL won't draw anything. Here the problem was the same. So I modified the 3D core to don't stop vertex list at each glMaterial call, and then the characters in Mario Party now look correct.
There're still some bugs in this game : some lighting bugs, and the star being badly placed and giant !
Here're two shots of Mario Party, I let you guess which one is the fixed one. :P
