Belmont /* Sega Saturn VDP2 */ /* the dirty marking stuff and tile decoding will probably be removed in the end anyway as we'll need custom rendering code since mame's drawgfx / tilesytem don't offer everything st-v needs this system seems far too complex to use Mame's tilemap system 4 'scroll' planes (scroll screens) the scroll planes have slightly different capabilities NBG0 NBG1 NBG2 NBG3 2 'rotate' planes RBG0 RBG1 -- other crap EXBG (external) ----------------------------------------------------------------------------------------------------------- Video emulation TODO: -all games: \-priorities (check myfairld,thunt) \-complete windows effects \-mosaic effect \-ODD bit/H/V Counter not yet emulated properly \-Reduction enable bits \-Check if there are any remaining video registers that are yet to be macroized & added to the rumble. -batmanfr: \-If you reset the game after the character selection screen,when you get again to it there's garbage floating behind Batman. -elandore: \-(BTANB) priorities at the VS. screen apparently is wrong,but it's like this on the Saturn version too. -hanagumi: \-ending screens have corrupt graphics. (*untested*) -kiwames: \-incorrect color emulation for the alpha blended flames on the title screen,it's caused by a schizoid linescroll emulation quirk. \-the VDP1 sprites refresh is too slow,causing the "Draw by request" mode to flicker.Moved back to default ATM. -pblbeach: \-Sprites are offset, because it doesn't clear vdp1 local coordinates set by bios, I guess that they are cleared when some vdp1 register is written (kludged for now) -prikura: \-Attract mode presentation has corrupted graphics in various places,probably caused by incomplete framebuffer data delete. -seabass: \-Player sprite is corrupt/missing during movements,caused by incomplete framebuffer switching. Notes of Interest & Unclear features: -the test mode / bios is drawn with layer NBG3; -hanagumi puts a 'RED' dragon logo in tileram (base 0x64000, 4bpp, 8x8 tiles) but its not displayed because its priority value is 0.Left-over? -scrolling is screen display wise,meaning that a scrolling value is masked with the screen resolution size values; -H-Blank bit is INDIPENDENT of the V-Blank bit...trying to fix enable/disable it during V-Blank period causes wrong gameplay speed in Golden Axe:The Duel. -Bitmaps uses transparency pens,examples are: \-elandore's energy bars; \-mausuke's foreground(the one used on the playfield) \-shanhigw's tile-based sprites; The transparency pen table is like this: |------------------|---------------------| | Character count | Transparency code | |------------------|---------------------| | 16 colors |=0x0 (4 bits) | | 256 colors |=0x00 (8 bits) | | 2048 colors |=0x000 (11 bits) | | 32,768 colors |MSB=0 (bit 15) | | 16,770,000 colors|MSB=0 (bit 31) | |------------------|---------------------| In other words,the first three types uses the offset and not the color allocated. -double density interlace setting (LSMD == 3) apparently does a lot of fancy stuff in the graphics sizes. -Debug key list(only if you enable the debug mode on top of this file): \-T: NBG3 layer toggle \-Y: NBG2 layer toggle \-U: NBG1 layer toggle \-I: NBG0 layer toggle \-O: SPRITE toggle \-K: RBG0 layer toggle \-W Decodes the graphics for F4 menu. \-M Stores VDP1 ram contents from a file. \-N Stores VDP1 ram contents into a file. */ #include "emu.h" #include "includes/saturn.h" // FIXME: this is a dependency from devices on MAME #include "screen.h" #define DEBUG_MODE 0 #define TEST_FUNCTIONS 0 #define POPMESSAGE_DEBUG 0 enum { STV_TRANSPARENCY_NONE, STV_TRANSPARENCY_PEN, STV_TRANSPARENCY_ADD_BLEND, STV_TRANSPARENCY_ALPHA }; #if DEBUG_MODE #define LOG_VDP2 1 #define LOG_ROZ 0 #else #define LOG_VDP2 0 #define LOG_ROZ 0 #endif /* -------------------------------------------------|-----------------------------|------------------------------ | Function | Normal Scroll Screen | Rotation Scroll Screen | | |-----------------------------|-----------------------------|------------------------------ | | NBG0 | NBG1 | NBG2 | NBG3 | RBG0 | RBG1 | -------------------------------------------------|-----------------------------|------------------------------ | Character Colour | 16 colours | 16 colours | 16 colours | 16 colours | 16 colours | 16 colours | | Count | 256 " " | 256 " " | 256 " " | 256 " " | 256 " " | 256 " " | | | 2048 " " | 2048 " " | | | 2048 " " | 2048 " " | | | 32768 " " | 32768 " " | | | 32768 " " | 32768 " " | | | 16770000 " " | | | | 16770000 " " | 16770000 " " | -------------------------------------------------|-----------------------------|------------------------------ | Character Size | 1x1 Cells , 2x2 Cells | -------------------------------------------------|-----------------------------|------------------------------ | Pattern Name | 1 word , 2 words | | Data Size | | -------------------------------------------------|-----------------------------|------------------------------ | Plane Size | 1 H x 1 V 1 Pages ; 2 H x 1 V 1 Pages ; 2 H x 2 V Pages | -------------------------------------------------|-----------------------------|------------------------------ | Plane Count | 4 | 16 | -------------------------------------------------|-----------------------------|------------------------------ | Bitmap Possible | Yes | No | Yes | No | -------------------------------------------------|-----------------------------|------------------------------ | Bitmap Size | 512 x 256 | N/A | 512x256 | N/A | | | 512 x 512 | | 512x512 | | | | 1024 x 256 | | | | | | 1024 x 512 | | | | -------------------------------------------------|-----------------------------|------------------------------ | Scale | 0.25 x -
