This loop takes roughly 24200 cycles, giving - 2500 + (24200 - 2500) * 2 * 60 = 2754000 = 2.75MHz for the CPU speed, - assuming 60 fps and a 2500 cycle VBLANK period. - This also matches the IGMO schematic, as it is the /CLK signal, which is - derived from the 11MHz xtal by dividing it down by two 74LS193 chips, one - (U92) dividing the clock by 2, and another (U91) having 3 taps, further - dividing the already divided clock by 2 (/CLK), 4 (/PLOAD) and 8 (CLOCK). - The CLOCK signal drives the AY. - - I think theglob2 is earlier than theglob. They only differ in one routine, - but it appears to be a bug fix. Also, theglob3 appears to be even older. - - To Do: - - - Super Blob uses a busy loop during the color test to split the screen - between the two palettes. This effect is not emulated, but since both - halves of the palette are identical, this is not an issue. See $039c. - The other games have a different color test, not using the busy loop. - - - dealer/beastf/revngr84: "PSG registers not OK" in service mode thru - sound menu, internal ay8910 not right? - -***************************************************************************/ - -#include "emu.h" -#include "includes/epos.h" - -#include "cpu/z80/z80.h" -#include "machine/i8255.h" -#include "machine/watchdog.h" -#include "machine/nvram.h" -#include "sound/ay8910.h" -#include "screen.h" -#include "speaker.h" - - -WRITE8_MEMBER(epos_state::dealer_decrypt_rom) -{ - if (offset & 0x04) - m_counter = (m_counter + 1) & 0x03; - else - m_counter = (m_counter - 1) & 0x03; - -// logerror("PC %08x: ctr=%04x\n",m_maincpu->pc(), m_counter); - - membank("bank1")->set_entry(m_counter); - - // is the 2nd bank changed by the counter or it always uses the 1st key? -} - - -/************************************* - * - * Main CPU memory handlers - * - *************************************/ - -void epos_state::epos_map(address_map &map) -{ - map(0x0000, 0x77ff).rom(); - map(0x7800, 0x7fff).ram(); - map(0x8000, 0xffff).ram().share("videoram"); -} - -void epos_state::dealer_map(address_map &map) -{ - map(0x0000, 0x5fff).bankr("bank1"); - map(0x6000, 0x6fff).bankr("bank2"); - map(0x7000, 0x7fff).ram().share("nvram"); - map(0x8000, 0xffff).ram().share("videoram"); -} - -/************************************* - * - * Main CPU port handlers - * - *************************************/ - -void epos_state::epos_io_map(address_map &map) -{ - map.global_mask(0xff); - map(0x00, 0x00).portr("DSW").w("watchdog", FUNC(watchdog_timer_device::reset_w)); - map(0x01, 0x01).portr("SYSTEM").w(FUNC(epos_state::port_1_w)); - map(0x02, 0x02).portr("INPUTS").w("aysnd", FUNC(ay8910_device::data_w)); - map(0x03, 0x03).portr("UNK"); - map(0x06, 0x06).w("aysnd", FUNC(ay8910_device::address_w)); -} - -void epos_state::dealer_io_map(address_map &map) -{ - map.global_mask(0xff); - map(0x00, 0x0f).w(FUNC(epos_state::dealer_pal_w)); - map(0x10, 0x13).rw("ppi8255", FUNC(i8255_device::read), FUNC(i8255_device::write)); - map(0x20, 0x24).w(FUNC(epos_state::dealer_decrypt_rom)); - map(0x34, 0x34).w("aysnd", FUNC(ay8910_device::data_w)); - map(0x38, 0x38).r("aysnd", FUNC(ay8910_device::data_r)); - map(0x3c, 0x3c).w("aysnd", FUNC(ay8910_device::address_w)); - map(0x40, 0x40).w("watchdog", FUNC(watchdog_timer_device::reset_w)); -} - -READ8_MEMBER(epos_state::i8255_porta_r) -{ - uint8_t data = 0xff; - - if (!BIT(m_input_multiplex, 0)) - data &= m_inputs[0]->read(); - - if (!BIT(m_input_multiplex, 1)) - data &= m_inputs[1]->read(); - - return data; -} - -/* - ROMs U01-U03 are checked with the same code in a loop. - There's a separate ROM check for banked U04 at 30F3. - It looks like dealer/revenger uses ppi8255 to control bankswitching. -*/ -WRITE8_MEMBER(epos_state::i8255_portc_w) -{ - membank("bank2")->set_entry(data & 0x01); - m_input_multiplex = (data >> 5) & 3; -} - -READ8_MEMBER(epos_state::ay_porta_mpx_r) -{ - return (m_ay_porta_multiplex ? 0xFF : ioport("DSW")->read()); -} - -WRITE8_MEMBER(epos_state::flip_screen_w) -{ - flip_screen_set(BIT(data, 7)); - // bit 6: ay8910 port A/B multiplexer read - m_ay_porta_multiplex = BIT(data, 6); -} - -/************************************* - * - * Port definitions - * - *************************************/ - -/* I think the upper two bits of port 1 are used as a simple form of protection, - so that ROMs couldn't be simply swapped.
