Macro Definition Documentation

◆ CHR_BANK

#define CHR_BANK ( n ) ((n) << 5)

◆ CHR_BANK_0

#define CHR_BANK_0 CHR_BANK(0)

◆ CHR_BANK_1

#define CHR_BANK_1 CHR_BANK(1)

◆ CHR_BANK_2

#define CHR_BANK_2 CHR_BANK(2)

◆ CHR_BANK_3

#define CHR_BANK_3 CHR_BANK(3)

◆ CHR_BANK_MASK

#define CHR_BANK_MASK 0x60

◆ CHR_BANK_SHIFT

#define CHR_BANK_SHIFT 5

◆ MAPPER_USE_1_SCREEN

#define MAPPER_USE_1_SCREEN asm(".globl __mirroring\n.globl __four_screen\n__mirroring = 0\n__four_screen = 1\n")

Define this in a .c file to use 1-screen switchable mirroring.

◆ MAPPER_USE_4_SCREEN_NAMETABLE

#define MAPPER_USE_4_SCREEN_NAMETABLE asm(".globl __mirroring\n.globl __four_screen\n__mirroring = 1\n__four_screen = 1\n")

Define this in a .c file to use 4-screen mirroring, with the last 8 KB of CHR-RAM dedicated to storing the four name tables.

In this mode, only banks 0-2 of CHR-RAM are fully safe to use for pattern table data.

◆ MAPPER_USE_SELF_FLASHABLE_BOARD

#define MAPPER_USE_SELF_FLASHABLE_BOARD asm(".globl __battery\n__battery = 1\n")

Define this in a .c file to use the self-flashable board.

This also protects against bus conflicts, removing the bus conflict table from the fixed ROM bank.

◆ MIRROR_SCREEN_1

#define MIRROR_SCREEN_1 0x00

◆ MIRROR_SCREEN_2

#define MIRROR_SCREEN_2 0x80

◆ MIRROR_SCREEN_MASK

#define MIRROR_SCREEN_MASK 0x80

◆ MIRROR_SCREEN_SHIFT

#define MIRROR_SCREEN_SHIFT 7

◆ PRG_BANK_MASK

#define PRG_BANK_MASK 0x1F

◆ PRG_BANK_SHIFT

#define PRG_BANK_SHIFT 0
