Macro Definition Documentation

◆ CGRAM_PALETTE

#define CGRAM_PALETTE ((u8 *)0x2122)

Palette CGRAM Data Write (W) 1st Access: Lower 8 bits (even address) 2nd Access: Upper 7 bits (odd address) (upper 1bit = PPU2 open bus)

Reads and Writes to EVEN and ODD byte-addresses work as follows: Write to EVEN address --> set Cgram_Lsb = Data ;memorize value Write to ODD address --> set WORD[addr-1] = Data*256 + Cgram_Lsb Read from ANY address --> return BYTE[addr]

The address is automatically incremented after every read or write access.

256-Color Palette Entries 15 Not used (should be zero) (read: PPU2 Open Bus) 14-10 Blue 9-5 Green 4-0 Red

Palette Indices 00h Main Backdrop color (used when all BG/OBJ pixels are transparent) 01h-FFh 256-color BG palette (when not using direct-color mode) 01h-7Fh 128-color BG palette (BG2 in Mode 7) 01h-7Fh Eight 16-color BG palettes 01h-1Fh Eight 4-color BG palettes (except BG2-4 in Mode 0) 21h-3Fh Eight 4-color BG palettes (BG2 in Mode 0 only) 41h-5Fh Eight 4-color BG palettes (BG3 in Mode 0 only) 61h-7Fh Eight 4-color BG palettes (BG4 in Mode 0 only) 81h-FFh Eight 16-color OBJ palettes (half of them with color-math disabled) N/A Sub Backdrop color (not in CGRAM, set via COLDATA, Port 2132h)

◆ REG_CGADSUB

#define REG_CGADSUB (*(vuint8 *)0x2131)

Color Math Control Register B (W) 7 Color Math Add/Subtract (0=Add; Main+Sub, 1=Subtract; Main-Sub) 6 Color Math "Div2" Half Result (0=No divide, 1=Divide result by 2) 5 Color Math when Main Screen = Backdrop (0=Off, 1=On) ;\ 4 Color Math when Main Screen = OBJ/Palette4..7 (0=Off, 1=On) ; OFF: Show.

Color Math when Main Screen = OBJ/Palette0..3 (Always=Off) ; Raw Main, 3 Color Math when Main Screen = BG4 (0=Off, 1=On) ; or 2 Color Math when Main Screen = BG3 (0=Off, 1=On) ; ON: Show 1 Color Math when Main Screen = BG2 (0=Off, 1=On) ; Main+/-Sub 0 Color Math when Main Screen = BG1 (0=Off, 1=On) ;/

◆ REG_INIDISP

#define REG_INIDISP (*(vuint8 *)0x2100)

Display Control 1 (W) 7 Forced Blanking (0=Normal, 1=Screen Black) 6-4 Not used 3-0 Master Brightness (0=Screen Black, or N=1..15: Brightness*(N+1)/16)

In Forced Blank, VRAM, OAM and CGRAM can be freely accessed (otherwise it's accessible only during Vblank). Even when in forced blank, the TV Set keeps receiving Vsync/Hsync signals (thus producing a stable black picture). And, the CPU keeps receiving Hblank/Vblank signals (so any enabled video NMIs, IRQs, HDMAs are kept generated).

Forced blank doesn't apply immediately... so one must wait whatever (maybe a scanline) before VRAM can be freely accessed... or is it only vice-versa: disabling forced blank doesn't apply immediately/shows garbage pixels?

◆ REG_M7SEL

#define REG_M7SEL (*(vuint8 *)0x211A)

Rotation/Scaling Mode Settings (W) 7-6 Screen Over (see below) 5-2 Not used 1 Screen V-Flip (0=Normal, 1=Flipped) ; flip 256x256 "screen" 0 Screen H-Flip (0=Normal, 1=Flipped) ;.

Screen Over (when exceeding the 128x128 tile BG Map size): 0=Wrap within 128x128 tile area 1=Wrap within 128x128 tile area (same as 0) 2=Outside 128x128 tile area is Transparent 3=Outside 128x128 tile area is filled by Tile 00h

◆ REG_STAT77

#define REG_STAT77 (*(vuint8 *)0x213E)

PPU1 Status and Version Number (R) 7 OBJ Time overflow (0=Okay, 1=More than 8x34 OBJ pixels per scanline) 6 OBJ Range overflow (0=Okay, 1=More than 32 OBJs per scanline) 5 Master/Slave Mode (PPU1.Pin25) (0=Normal=Master) 4 Not used (PPU1 open bus) (same as last value read from PPU1) 3-0 PPU1 5C77 Version Number (only version 1 exists as far as I know)

The overflow flags are cleared at end of V-Blank, but NOT during forced blank! The overflow flags are set (regardless of OBJ enable/disable in 212Ch), at following times: Bit6 when V=OBJ.YLOC/H=OAM.INDEX*2, bit7 when V=OBJ.YLOC+1/H=0.

◆ REG_VMADDLH

#define REG_VMADDLH (*(vuint16 *)0x2116)

VMADDL - VRAM Address (lower 8bit) (W) VMADDH - VRAM Address (upper 8bit) (W)

VRAM Address for reading/writing. This is a WORD address (2-byte steps), the PPU could theoretically address up to 64K-words (128K-bytes), in practice, only 32K-words (64K-bytes) are installed in SNES consoles (VRAM address bit15 is not connected, so addresses 8000h-FFFFh are mirrors of 0-7FFFh). After reading/writing VRAM Data, the Word-address can be automatically incremented by 1,32,128 (depending on the Increment Mode in Port 2115h) (Note: the Address Translation feature is applied only "temporarily" upon memory accesses, it doesn't affect the value in Port 2116h-17h). Writing to 2116h/2117h does prefetch 16bit data from the new address (for later reading).

◆ REG_VMAIN

#define REG_VMAIN (*(vuint8 *)0x2115)

VRAM Address Increment Mode (W) 7 Increment VRAM Address after accessing High/Low byte (0=Low, 1=High) 6-4 Not used 3-2 Address Translation (0..3 = 0bit/None, 8bit, 9bit, 10bit) 1-0 Address Increment Step (0..3 = Increment Word-Address by 1,32,128,128)

The address translation is intended for bitmap graphics (where one would have filled the BG Map by increasing Tile numbers), technically it does thrice left-rotate the lower 8, 9, or 10 bits of the Word-address: Translation Bitmap Type Port [2116h/17h] VRAM Word-Address 8bit rotate 4-color; 1 word/plane aaaaaaaaYYYxxxxx --> aaaaaaaaxxxxxYYY 9bit rotate 16-color; 2 words/plane aaaaaaaYYYxxxxxP --> aaaaaaaxxxxxPYYY 10bit rotate 256-color; 4 words/plane aaaaaaYYYxxxxxPP --> aaaaaaxxxxxPPYYY

Where "aaaaa" would be the normal address MSBs, "YYY" is the Y-index (within a 8x8 tile), "xxxxx" selects one of the 32 tiles per line, "PP" is the bit-plane index (for BGs with more than one Word per plane). For the intended result (writing rows of 256 pixels) the Translation should be combined with Increment Step=1. For Mode 7 bitmaps one could eventually combine step 32/128 with 8bit/10bit rotate:

8bit-rotate/step32 aaaaaaaaXXXxxYYY --> aaaaaaaaxxYYYXXX 10bit-rotate/step128 aaaaaaXXXxxxxYYY --> aaaaaaxxxxYYYXXX

Though the SNES can't access enough VRAM for fullscreen Mode 7 bitmaps. Step 32 (without translation) is useful for updating BG Map columns (eg. after horizontal scrolling).
