There are 2 tilemaps: A 32x32 3BPP one with tile column scroll. A 32x32 1BPP one fixed. 1BPP tilemap is always shown under the main tilemap (maybe some video register controls this). The video hardware supports 8 16x16 sprites, built from 4 consecutive 8x8 tiles, so the low 2 bits of the tile code are not specified in the sprite list. Also there is support for up to 8 bullets, currently drawn as a pixel with white colour. The game supports an unemulated starfield, with fading stars. It's currently unknown how it works. Tiles are stored in 6 banks of 256 tiles, the current bank applies to sprite and tile codes. VIDEO RAM STRUCTURE A000-A3FF - 3bpp Tile layer tile code A400-A7FF - ?? doesn't seem used A800-A83F - Tile column scroll on even bytes. Tile column palette on odd bytes. A840-A85F - 8 sprites. 4 bytes per sprite: 76543210 0 YYYYYYYY Y position of the sprite 1 yxCCCCCC x: xflip y: yflip C: sprite code (of a 4 sprites block) 2 -----PPP P: Palette 3 XXXXXXXX X position of the sprite A860-A87F - Bullets. 4 bytes per bullet 0 -------- Unknown (X pos high byte?) 1 XXXXXXXX X position of the bullet 2 -------- Unknown (Y pos high byte?) 3 YYYYYYYY Y position of the bullet AC00-AFFF - 1bpp Tile layer tile code VIDEO REGISTERS Most video registers are unknown :( B400 - This is usually 1, but changes to 2 sometimes during scenes, also toggles 0x80 on and off in the interrupt handler before changing some regs (disable interrupt while on interrupt?) B401 - Always 00 B402 - Always 00 B403 - Starfield on/off. Pretty sure it is. B404 - Always FF B405 - Tile column scroll on/off. Almost, but not, because it's set to 0 on the galaxian stage, and it has scrolling on the top rows B406 - 1bpp tilemap on/off ?. Almost but not, because it's set to 0 on the title screen and the niemer text is on the 1bpp layer and must appear B407 - Tile bank B800 -\-- these 2 values contain ror(Tilebank,1), ror(Tilebank,2). Sprites bank? always set to the same than Tile bank reg B801 -/ B802 -\ these 3 registers usually contain x, ror(x,1), ror(x,2) and are related to the 1bpp bitmap palette color. 2 is red, used for the "galaxian" level lines B803 -|-- during the initial scene of the attract, when the bomb explodes, they cycle 1,2,3,3,3,3,4,5,6 to cycle several colors, yellow, blue and red B804 -/ in the logo screen, when it says "Fin del tiempo", the "Niemer" letters must be orange/brown, these are set to 3. Set to 7 in the survival stage (red laser) B805 - Always 00 B806 - Always 00 B807 - Always 00 Some video register dumps (B400): 01 00 00 01 FF 01 01 00 - first attract screen, starfield on, scroll not used, 1bpp layer used (for explosion) 01 00 00 01 FF 01 00 02 - first level (scrolling) , starfield on, scroll used, 1bpp layer not used 01 00 00 01 FF 01 01 03 - 2nd level (survival), starfield on, scroll not used, 1bpp layer used (for laser) 01 00 00 00 FF 01 01 04 - 3rd level (rescue), starfield off, scroll not used, 1bpp layer used (for tentacles) 01 00 00 01 FF 00 01 01 - 4rd level (galaxian), starfield on, scroll used, 1bpp layer used (red lines) 01 00 00 01 FF 01 01 05 - last level, starfield on, scroll not used, 1bpp layer not used 01 00 00 00 FF 01 00 01 - Logo screen, starfield off, scroll not used, 1bpp layer used (niemer logo) 01 00 00 00 FF 01 00 01 - Scoring, starfield off, scroll used, 1bpp layer not used *********************************************************************************** Pinout: Components | Solder side ------------------|--|--|------------------ GND |01| A| GND GND |02| B| GND GND |03| C| GND KEY (not used) |04| D| KEY (not used) +5V |05| E| +5V +5V |06| F| +5V Coin Counter |07| G| Audio Out (not amplified) N/C |08| H| N/C Player 1 Button 2 |09| I| Coin Counter Coin 1 |10| J| Player 1 Button 1 Start 2 Players |11| K| Coin 2 Player 1 Left |12| L| Player 1 Right Player 1 Up |13| M| Start 1 Player Reset PCB (*) |14| N| Player 1 Down Green |15| O| Video Sync Blue |16| P| Red N/C |17| Q| -5V +12V |18| R| +12V (*) Needs to be tied to GND in order to boot. **********************************************************************************/ #include "emu.h" #include "includes/efdt.h" #include "cpu/z80/z80.h" #include "cpu/m6800/m6800.h" #include "machine/watchdog.h" #include "sound/ay8910.h" #include "screen.h" #include "speaker.h" #define MAIN_CLOCK 18.432_MHz_XTAL #define SEC_CLOCK 14.318181_MHz_XTAL #define Z80_CLOCK MAIN_CLOCK / 6 // 3.0720 MHz.
