2 Bg's and 2 Color Palletes

Well, I rant into a funny problem. No matter what turns i give into the matter, I can't seem to set 2 palletes in 2 layers. Actually, I can't define a color offset at all!

For example...

Code: 
  
slPageNbg1((void *)NBG1_TILE_N1 ,0x00, PNB_1WORD|CN_12BIT);

and i have these define's

#define NBG1_CRAM ( VDP2_COLRAM + 0x00000 )

#define NBG2_CRAM ( VDP2_COLRAM + 0x00200 )

The second value of slPage is supposed to set the pallete location. Strangely, i tried various values (0x01, NBG1_CRAM, 0xFF, 0x200) and nothing really seems to work. It gives allways the same pattete, the one that starts at VDP2_COLRAM. 

I could use direct VDP2 registry access, but as this is for the tutorials, so it would be nice to use SGL calls only.

*Edit, stupid error*

I wish I knew more about SGL ... the only questions I can think of after skimming the SGL docs are: what color RAM mode are you in, and what kind of calls are you making to the slCharNBG functions? Those seem like they're relevant anyway .

Well, here's the whole init code :



slInitSystem(TV_320x224, NULL, 1);

slColRAMMode(CRM16_1024);

slCharNbg1(COL_TYPE_256 , CHAR_SIZE_1x1);

slCharNbg2(COL_TYPE_256 , CHAR_SIZE_1x1);

slPageNbg1((void *)NBG1_TILE_N1 ,0x00, PNB_1WORD|CN_12BIT);

slPageNbg2((void *)NBG2_TILE_N2 ,0x00, PNB_1WORD|CN_12BIT);

slScrTransparent(NBG2ON);

slPlaneNbg1(PL_SIZE_1x1);

slPlaneNbg2(PL_SIZE_1x1);

slMapNbg1((void *)NBG1_MAP_N1 , (void *)NBG1_MAP_N1 , (void *)NBG1_MAP_N1 , (void *)NBG1_MAP_N1);

slMapNbg2((void *)NBG2_MAP_N2 , (void *)NBG2_MAP_N2 , (void *)NBG2_MAP_N2 , (void *)NBG2_MAP_N2);

LoadFile("PIC2.BIN",(void*) LO_WRAM, 512);

ReadScr((void*) LO_WRAM,(void*) NBG1_TILE_N1,(void*) NBG1_MAP_N1,(void*) NBG1_CRAM_N1);

slPrint("File1 Loadeds", slLocate(5,1));

LoadFile("PIC2.BIN",(void*) LO_WRAM, 512);

ReadScr((void*) LO_WRAM,(void*) NBG2_TILE_N2,(void*) NBG2_MAP_N2,(void*) NBG1_CRAM_N1);

slPrint("File1 Loaded", slLocate(5,2));

slTVOn();
