One column = 2 tiles

Two pattern attributes are written in VRAM as two consecutives 16-bit words:
|
|
|
|
|
|
|
|
P = priority bit
|
|
|
|
C = color palette (2 bits)
|
|
|
|
V = Vertical Flip bit
|
|
|
|
H = Horizontal Flip bit
|
|
|
|
N = Pattern Number (11 bits)
|
|
|
|
|
|
|
|
(MSB) PCCVHNNN NNNNNNNN (LSB) (MSB) PCCVHNNN NNNNNNNN (LSB)
|
|
|
|
PATTERN1 PATTERN2
|
|
|
|
|
|
|
|
Both pattern attributes are read from VRAM as one 32-bit word:
|
|
|
|
|
|
|
|
LIT_ENDIAN: (MSB) PCCVHNNN NNNNNNNN PCCVHNNN NNNNNNNN (LSB)
|
|
|
|
PATTERN2 PATTERN1

|
|
|
|
PATTERN1 PATTERN2
|
|
|
|
|
|
|
|
|
|
|
|
In line buffers, one pixel = one byte: (msb) 0Pppcccc (lsb)
|
|
|
|
with:
|
|
|
|
P = priority bit (from pattern attribute)
|
|
|
|
p = color palette (from pattern attribute)
|
|
|
|
c = color data (from pattern cache)
|
|
|
|
|
|
|
|
One pattern = 8 pixels = 8 bytes = two 32-bit writes per pattern

* fixed Micro Machines 2 - Turbo Tournament EEPROM size (verified on real cartridge).
* modified SRAM banswitch hardware emulation to be more compatible with some hacks.
[Core/MS]
---------------
* added Cyborg Z to Korean mapper database.
[Core/GG]
---------------
* added 93C46 EEPROM emulation (Majors Pro Baseball, World Series Baseball & World Series Baseball 95).
[Core/General]
---------------
* added support for .mdx ROM format.
* added Game Gear & SG-1000 ROM support.
* added accurate emulation of SG-1000, Master System (I, II) & Game Gear hardware models for 100% compatibility.
* updated to new Genesis Plus license (see http://cgfm2.emuviews.com/)
* removed DOS port
* various code cleanup.
[Gamecube/Wii]
---------------
* IMPORTANT: cheats, screenshots & save files are now stored in console-specific directories (ex: /snaps/md, /cheats/ms, /saves/gg, ...)
* added 8-bit Action Replay & Game Genie codes support (for Master System & Game Gear games).
* improved audio/video synchronization for PAL games in 50Hz TV modes (now use VSYNC like NTSC games in 60hz modes).
* improved gun cursor positioning accuracy.
* improved horizontal scaling & screenshots rendering in H32 mode.
* fixed a bug with ROM file extension handling that would affect cheats, snapshots, sram & savestate files.
* removed ARAM/injected ROM support (unused).
* removed WPAD_ and PAD_ update from VSYNC callback.
* increased GCC inlining limits for some speed improvment.
* compiled with devkitPPC r24 & libogc 1.8.7.
