Re: [cadcdev-tiki] initial SDL and DC ports pushed to SVN

[Sam S. <sam...@gm...>]

Ok, I had to fight with it a bit to get it to build.  The main issues  
are conflicts between Tiki and KOS, for example dc/matrix.h breaks  
plxcompat.cpp.  On the original tree, I #if'ed the sections of  
plxcompat.cpp that conflict out, and I think that's why the bubbles  
demo didn't show anything (the wrong matrices are being updated).   
This time, I modified kos.h so it doesn't include dc/matrix.h and  
left plxcompat.cpp intact, and the bubbles demo works!  Well, it runs  
pretty poorly, but at least it displays something :)

I also had to pull over thread.cpp from your original tree, since you  
forgot to add those changes to the new tree.

The changes I've made so far are to replace tikimath.h / math.cpp  
with dc/fmath.h, which makes the bubbles demo run much faster (though  
still not as fast as the original parallax version).  I also merged  
in my changes to texture.cpp, and added a glKosFinishList() to  
Frame::transEnable(), which should really go into  
tiki_scene_begin_trans_hook() but it doesn't appear that's being  
called (yet).  I also had to #if out some parts of Frame::begin()  
that use constants that aren't part of KGL.

I'm now at the point where TikiBlap compiles and runs, however I'm  
still hitting a few quirks.  I still can't get textures to display  
with KGLX, all my polygons are just white.  However, if I use KGL  
textures work fine, but my genmenu objects (located at z=0) wont show  
up unless I flip the depth buffer, which causes the stacking order to  
be inconsistent between the two platforms (if I put something at  
z=0.1, is it on top of or below z=0.0?).  I'll try to compare KGL and  
KGLX and see if I can either fix KGLX's textures or KGL's coordinate  
system.  Finally, I'm still getting crashes when loading wav files --  
"snd_mem_free: attempt to free non-existant block at 00000000".  I'll  
try to track that down too.
