IO register types
typedef struct POINT16	POINT16
	Regular bg points; range: :0010 - :001F.

typedef struct POINT16	BG_POINT
	Regular bg points; range: :0010 - :001F.

typedef struct AFF_DST_EX	BG_AFFINE
	Affine parameters for backgrounds; range : 0400:0020 - 0400:003F.

typedef struct DMA_REC	DMA_REC
	DMA struct; range: 0400:00B0 - 0400:00DF.

typedef struct TMR_REC	TMR_REC
	Timer struct, range: 0400:0100 - 0400:010F.

PAL types
typedef COLOR	PALBANK[16]
	Palette bank type, for 16-color palette banks.

VRAM array types
These types allow VRAM access as arrays or matrices in their most natural types.
typedef SCR_ENTRY	SCREENLINE[32]

typedef SCR_ENTRY	SCREENMAT[32][32]

typedef SCR_ENTRY	SCREENBLOCK[1024]

typedef COLOR	M3LINE[240]

typedef u8	M4LINE[240]

typedef COLOR	M5LINE[160]

typedef TILE	CHARBLOCK[512]

typedef TILE8	CHARBLOCK8[256]

OAM structs
Note These OBJ_ATTR and OBJ_AFFINE structs are interlaced in OAM. When using affine objs, struct/DMA/mem copies will give bad results.
typedef struct OBJ_ATTR	OBJ_ATTR
	Object attributes.

typedef struct OBJ_AFFINE	OBJ_AFFINE
	Object affine parameters.

Detailed Description

These types are used for memory mapping of VRAM, affine registers and other areas that would benefit from logical memory mapping.

Typedef Documentation

Object affine parameters.

Object attributes.

Note: attribute 3 is padding for the interlace with OBJ_AFFINE. If not using affine objects, it can be used as a free field

typedef struct TMR_REC TMR_REC

Timer struct, range: 0400:0100 - 0400:010F.
