// license:BSD-3-Clause // copyright-holders:Zsolt Vasvari /*************************************************************************** Epos games driver by Zsolt Vasvari Notes: - To walk in IGMO, hold down button 2. - Super Glob seems like a later revision of The Glob, the most obvious difference being an updated service mode. - These games don't have cocktail mode. - The CPU clock divisor 4 was derived using the timing loop used to split the screen in the middle. 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.
