glNormal

* glNormal3d, glNormal3f

{size: 0x3   channel: 0x1   cmd: 0x00000c30}

value are encoded as FP32

* glNormal3i, glNormal3s, glNormal3b

{size: 0x2   channel: 0x1   cmd: 0x00000c40}

values can be encoded as INT2FLOAT in 16 bits mode

glTexCoord

#define NV15_TEX0_COORD_4_FLOAT 0xca0
#define NV15_TEX0_COORD_2_FLOAT 0xc90
#define NV15_TEX1_COORD_4_FLOAT 0xcc8
#define NV15_TEX1_COORD_2_FLOAT 0xcb8

encoded as FP32 2 or 4 arguments

#define NV15_TEX0_COORD_2_SHORT 0xcb0
#define NV15_TEX0_COORD_1_SHORT 0xc98
#define NV15_TEX1_COORD_2_SHORT 0xcd8
#define NV15_TEX1_COORD_1_SHORT 0xcc0

encoded as signed 16BITS INTERGER the lower 16 bits are the first value the higher 16 bits are the first value

For example glTexCoord4s(0,128,-127, 256); will give

2b5   0x00000000   0x00082cb0   {size: 0x2   channel: 0x1   cmd: NV15_TEX_COORD_4_SHORT}
2b6   0x00000000   0x00800000  (16 BITS INTEGER: 128 | 0)  
2b7   0x00000000   0x0100ff81  (16 BITS INTEGER: 256 | 65409)
