/* Brazilian bootleg board from 1989. Forte II Games, Industria Brasileira. MAME driver by Mariusz Wojcieszek & hap, based on information from Alexandre. Hardware is based on MSX1, excluding i8255 PPI: 64KB RAM, largely unused 64KB EPROM (2764-15, contains hacked BIOS and game ROM) Z80 @ 3.58MHz GI AY-3-8910 TI TMS9928A (no dipswitches) Games: Pesadelo (means Nightmare in Portuguese), 1989 bootleg of Knightmare (Majou Densetsu in Japan) (C) 1986 Konami, originally released exclusively on MSX. This arcade conversion has been made a bit harder, eg. bonus power-ups deplete three times quicker, and the game starts at a later, more difficult level. A rough translation of the text after inserting a coin: Coins won't accumulate, insert a new coin after the game is over if you want another play. According to Alexandre, there are more games for this board, but not found/dumped yet. */ #include "emu.h" #include "cpu/z80/z80.h" #include "video/tms9928a.h" #include "sound/ay8910.h" class forte2_state : public driver_device { public: forte2_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) { } UINT8 m_input_mask; }; static ADDRESS_MAP_START( program_mem, AS_PROGRAM, 8 ) AM_RANGE(0x0000, 0xbfff) AM_ROM AM_RANGE(0xc000, 0xffff) AM_RAM ADDRESS_MAP_END static ADDRESS_MAP_START( io_mem, AS_IO, 8 ) ADDRESS_MAP_UNMAP_HIGH ADDRESS_MAP_GLOBAL_MASK(0xff) AM_RANGE(0x98, 0x98) AM_DEVREADWRITE_MODERN( "tms9928a", tms9928a_device, vram_read, vram_write ) AM_RANGE(0x99, 0x99) AM_DEVREADWRITE_MODERN( "tms9928a", tms9928a_device, register_read, register_write ) AM_RANGE(0xa0, 0xa1) AM_DEVWRITE("aysnd", ay8910_address_data_w) AM_RANGE(0xa2, 0xa2) AM_DEVREAD("aysnd", ay8910_r) /* Ports a8-ab are originally for communicating with the i8255 PPI on MSX.
