/*************************************************************************** Gaplus (c) 1984 Namco driver by Manuel Abadia, Ernesto Corvi, Nicola Salmoria Custom ICs: ---------- 11XX gfx data shifter and mixer (16-bit in, 4-bit out) [1] 15XX sound control 16XX I/O control CUS20 tilemap and sprite address generator CUS21 sprite generator CUS26 starfield generator CUS29 sprite line buffer and sprite/tilemap mixer CUS33 timing generator CUS34 address decoder 56XX I/O 58XX I/O CUS62 I/O and explosion generator 98XX lamp/coin output 99XX sound volume memory map ---------- Most of the address decoding for main and sound CPU is done by a custom IC (34XX), so the memory map is largely deducted by program behaviour. The 34XX also handles internally the main and sub irq, and a watchdog. Most of the address decoding for sub CPU is done by a PAL which was read and decoded, but there are some doubts about its validity. There is also some additional decoding for tile/sprite RAM done by the 20XX tilemap and sprite address generator. Note: chip positions are based on the Midway version schematics. The Namco version has a different layout (see later for the known correspondencies) MAIN CPU: Address Dir Data Name Description ---------------- --- -------- --------- ----------------------- 00000xxxxxxxxxxx R/W xxxxxxxx RAM 9J tilemap RAM (shared with sub CPU) 00001xxxxxxxxxxx R/W xxxxxxxx RAM 3M work RAM (shared with sub CPU) 000011111xxxxxxx R/W xxxxxxxx portion holding sprite registers (sprite number & color) 00010xxxxxxxxxxx R/W xxxxxxxx RAM 3K work RAM (shared with sub CPU) 000101111xxxxxxx R/W xxxxxxxx portion holding sprite registers (x, y) 00011xxxxxxxxxxx R/W xxxxxxxx RAM 3L work RAM (shared with sub CPU) 000111111xxxxxxx R/W xxxxxxxx portion holding sprite registers (x msb, flip, size) 01100-xxxxxxxxxx R/W xxxxxxxx SOUND RAM (shared with sound CPU) 01101-----xxxxxx R/W ----xxxx FBIT I/O chips 0111x----------- W -------- main CPU irq enable (data is in A11) (MIRQ generated by 34XX) 01111----------- R -------- watchdog reset (MRESET generated by 34XX) 1000x----------- W -------- SRESET reset sub and sound CPU, sound enable (data is in A11) (latch in 34XX) 1001x----------- W -------- FRESET reset I/O chips (data is in A11) (latch in 34XX) 10100---------xx W xxxxxxxx STWR to custom 26XX (starfield control) 10-xxxxxxxxxxxxx R xxxxxxxx ROM 9E program ROM (can optionally be a 27128) 110xxxxxxxxxxxxx R xxxxxxxx ROM 9D program ROM 111xxxxxxxxxxxxx R xxxxxxxx ROM 9C program ROM [1] Program uses addresses with A10 = 1, e.g. 7400, 7c00, but A10 is not used. On startup, it also writes to 7820-782f. This might be a bug, the intended range being 6820-682f to address the 3rd I/O chip. SOUND CPU: Address Dir Data Name Description ---------------- --- -------- --------- ----------------------- 000---xxxxxxxxxx R/W xxxxxxxx SOUND2 RAM (shared with main CPU) 001------------- R/W -------- watchdog reset? (34XX) [1] 01x------------- W -------- sound CPU irq enable (data is in A13) (SIRQ generated by 34XX) 11-xxxxxxxxxxxxx R xxxxxxxx ROM 7B program ROM (can optionally be a 27128) [1] Program writes to 3000 and on startup reads from 3000. On startup it also writes to 2007, but there doesn't seem to be anything else there. SUB CPU: Address Dir Data Name Description ---------------- --- -------- --------- ----------------------- 00000xxxxxxxxxxx R/W xxxxxxxx RAM 9J tilemap RAM (shared with main CPU) 00001xxxxxxxxxxx R/W xxxxxxxx RAM 3M work RAM (shared with main CPU) 000011111xxxxxxx R/W xxxxxxxx portion holding sprite registers (sprite number & color) 00010xxxxxxxxxxx R/W xxxxxxxx RAM 3K work RAM (shared with main CPU) 000101111xxxxxxx R/W xxxxxxxx portion holding sprite registers (x, y) 00011xxxxxxxxxxx R/W xxxxxxxx RAM 3L work RAM (shared with main CPU) 000111111xxxxxxx R/W xxxxxxxx portion holding sprite registers (x msb, flip, size) 0110-----------x -------- VINTON sub CPU irq enable (data is in A0) [1] 10-xxxxxxxxxxxxx R xxxxxxxx ROM 6L program ROM (can optionally be a 27128) 110xxxxxxxxxxxxx R xxxxxxxx ROM 6M program ROM 111xxxxxxxxxxxxx R xxxxxxxx ROM 6N program ROM [1] Program normally uses 6080/6081, but 6001 is written on startup. 500F is also written on startup, whose meaning is unknown. ROM chip placements ------------------- Midway Namco ------ ----- 9C 8B 9D 8C 9E 8D 6N 11B 6M 11C 6L 11D 7B 4B 9L 8S 5K 11R 5L 11N 5M 11P 5N 11M ---------------------------------------------------------------------------- Notes: ------ - Easter egg: - enter service mode - keep P1 start and P1 button pressed - move joystick left until sound reaches 19 (c) 1984 NAMCO will appear on the screen - most sets always say "I/O OK", even if the custom I/O checks fail. Only gapluso and gaplusa stop working; these two also don't do the usual Namco-trademark RAM test on startup, and use the first I/O chip in "coin" mode, while the others use it in "switch/lamp" mode. - gaplusa has the 58XX and 56XX inverted. Why would they do that? - To use Round Advance: turn the dip switch on before the start of a level. Push joystick up to pick a later level, then set the dip switch back to off. - The only difference between galaga3a and galaga3m is the bonus life settings. TODO: - The starfield is wrong. - schematics show 4 lines going from the 58XX I/O chip to the 26XX (starfield generator). Function and operation unknown. - Add 62XX custom to machine/namcoio.c (though it's quite different from 56XX and 58XX). - Is the sprite generator the same as Phozon? This isn't clear yet. They are very similar, especially in the way the size flags are layed out. ***************************************************************************/ #include "emu.h" #include "cpu/m6809/m6809.h" #include "machine/namcoio.h" #include "machine/namco62.h" #include "sound/namco.h" #include "sound/samples.h" #include "includes/gaplus.h" static READ8_HANDLER( gaplus_spriteram_r ) { gaplus_state *state = space->machine().driver_data(); return state->m_spriteram[offset]; } static WRITE8_HANDLER( gaplus_spriteram_w ) { gaplus_state *state = space->machine().driver_data(); state->m_spriteram[offset] = data; } static WRITE8_HANDLER( gaplus_irq_1_ctrl_w ) { int bit = !BIT(offset, 11); cpu_interrupt_enable(space->machine().device("maincpu"), bit); if (!bit) cputag_set_input_line(space->machine(), "maincpu", 0, CLEAR_LINE); } static WRITE8_HANDLER( gaplus_irq_3_ctrl_w ) { int bit = !BIT(offset, 13); cpu_interrupt_enable(space->machine().device("sub2"), bit); if (!bit) cputag_set_input_line(space->machine(), "sub2", 0, CLEAR_LINE); } static WRITE8_HANDLER( gaplus_irq_2_ctrl_w ) { int bit = offset & 1; cpu_interrupt_enable(space->machine().device("sub"), bit); if (!bit) cputag_set_input_line(space->machine(), "sub", 0, CLEAR_LINE); } static WRITE8_HANDLER( gaplus_sreset_w ) { int bit = !BIT(offset, 11); cputag_set_input_line(space->machine(), "sub", INPUT_LINE_RESET, bit ?
