There might + be some mistakes. The diagram actually shows 4 PROMs on the ROM board + (a37-17, -18, -19 and -20), while we only have one: 82s191n. I think it's + possible that the single 2KB PROM replaced four 512B PROMs in a later + revision of the board. + +- The video hardware (especially the sprite system) is quite obviously derived + from a Namco design. + +- Two bits of tilemap RAM might be used for tile flip, but the game never sets + them so we can't verify without schematics. + +- We don't have a dump of the original MCU. We have a dump from a bootleg MCU, + which however cannot be the same as the original. The game works fine with it, + but only when the flip screen dip switch is set to off. If it is set to on, it + hangs when starting a game because the mcu doesn't answer a command. + See MCU code at $206 and $435: when the dip switch is on, the lda #$00 should + be replaced by lda #$01. + +***************************************************************************/ + +#include "driver.h" +#include "cpu/m6805/m6805.h" +#include "sound/sn76496.h" + +/* in machine */ +READ8_HANDLER( retofinv_68705_portA_r ); +WRITE8_HANDLER( retofinv_68705_portA_w ); +WRITE8_HANDLER( retofinv_68705_ddrA_w ); +READ8_HANDLER( retofinv_68705_portB_r ); +WRITE8_HANDLER( retofinv_68705_portB_w ); +WRITE8_HANDLER( retofinv_68705_ddrB_w ); +READ8_HANDLER( retofinv_68705_portC_r ); +WRITE8_HANDLER( retofinv_68705_portC_w ); +WRITE8_HANDLER( retofinv_68705_ddrC_w ); +WRITE8_HANDLER( retofinv_mcu_w ); +READ8_HANDLER( retofinv_mcu_r ); +READ8_HANDLER( retofinv_mcu_status_r ); + +/* in video */ +VIDEO_START( retofinv ); +PALETTE_INIT( retofinv ); +VIDEO_UPDATE( retofinv ); +READ8_HANDLER( retofinv_bg_videoram_r ); +READ8_HANDLER( retofinv_fg_videoram_r ); +WRITE8_HANDLER( retofinv_bg_videoram_w ); +WRITE8_HANDLER( retofinv_fg_videoram_w ); +WRITE8_HANDLER( retofinv_gfx_ctrl_w ); + +extern UINT8 *retofinv_fg_videoram; +extern UINT8 *retofinv_bg_videoram; +extern UINT8 *retofinv_sharedram; + +static UINT8 cpu2_m6000=0; + + +static WRITE8_HANDLER( cpu1_reset_w ) +{ + cpunum_set_input_line(1, INPUT_LINE_RESET, data ?
