/*************************************************************************** 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 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 should be easy to check since the schematics are available, . - 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 halfs 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. ***************************************************************************/ #include "emu.h" #include "cpu/z80/z80.h" #include "machine/8255ppi.h" #include "sound/ay8910.h" #include "includes/epos.h" static WRITE8_HANDLER( dealer_decrypt_rom ) { epos_state *state = space->machine().driver_data(); if (offset & 0x04) state->m_counter = (state->m_counter + 1) & 0x03; else state->m_counter = (state->m_counter - 1) & 0x03; // logerror("PC %08x: ctr=%04x\n",cpu_get_pc(&space->device()), state->m_counter); memory_set_bank(space->machine(), "bank1", state->m_counter); // is the 2nd bank changed by the counter or it always uses the 1st key? } /************************************* * * Main CPU memory handlers * *************************************/ static ADDRESS_MAP_START( epos_map, AS_PROGRAM, 8 ) AM_RANGE(0x0000, 0x77ff) AM_ROM AM_RANGE(0x7800, 0x7fff) AM_RAM AM_RANGE(0x8000, 0xffff) AM_RAM AM_BASE_SIZE_MEMBER(epos_state, m_videoram, m_videoram_size) ADDRESS_MAP_END static ADDRESS_MAP_START( dealer_map, AS_PROGRAM, 8 ) AM_RANGE(0x0000, 0x5fff) AM_ROMBANK("bank1") AM_RANGE(0x6000, 0x6fff) AM_ROMBANK("bank2") AM_RANGE(0x7000, 0x7fff) AM_RAM AM_RANGE(0x8000, 0xffff) AM_RAM AM_BASE_SIZE_MEMBER(epos_state, m_videoram, m_videoram_size) ADDRESS_MAP_END /************************************* * * Main CPU port handlers * *************************************/ static ADDRESS_MAP_START( io_map, AS_IO, 8 ) ADDRESS_MAP_GLOBAL_MASK(0xff) AM_RANGE(0x00, 0x00) AM_READ_PORT("DSW") AM_WRITE(watchdog_reset_w) AM_RANGE(0x01, 0x01) AM_READ_PORT("SYSTEM") AM_WRITE(epos_port_1_w) AM_RANGE(0x02, 0x02) AM_READ_PORT("INPUTS") AM_DEVWRITE("aysnd", ay8910_data_w) AM_RANGE(0x03, 0x03) AM_READ_PORT("UNK") AM_RANGE(0x06, 0x06) AM_DEVWRITE("aysnd", ay8910_address_w) ADDRESS_MAP_END static ADDRESS_MAP_START( dealer_io_map, AS_IO, 8 ) ADDRESS_MAP_GLOBAL_MASK(0xff) AM_RANGE(0x10, 0x13) AM_DEVREADWRITE("ppi8255", ppi8255_r, ppi8255_w) AM_RANGE(0x20, 0x24) AM_WRITE(dealer_decrypt_rom) AM_RANGE(0x38, 0x38) AM_READ_PORT("DSW") // AM_RANGE(0x40, 0x40) AM_WRITE(watchdog_reset_w) ADDRESS_MAP_END /* ROMs U01-U03 are checked with the same code in a loop.
