However, a Tecmo-licensed green PCB reveals them to be none other than NMK-901, NMK-902 and NMK-903. Yam! Yam!? runs on similar hardware but has a protection device which can access RAM at e000. Program writes to e000 and expects a value back at e001, then jumps to subroutines at e010 and e020. Also, the player and coin inputs appear magically at e004-e006. Despite not using GFX customs or MCU protection and lacking Dooyong labels, gundealrbl might be a factory conversion of Yam! Yam!? rather than a bootleg, as its board has the same NMK-style markings for the ROM and PROM locations. In place of the MCU here is a small daughterboard with three SN74LS245N buffers, a resistor array and an Altera EP320PC. 0000-7fff ROM 8000-bfff ROM (banked) c400-c7ff palette RAM c800-cfff background video RAM d000-dfff foreground (scrollable) video RAM. e000-ffff work RAM read: c000 DSW0 c001 DSW1 c004 COIN (Gun Dealer only) c005 IN1 (Gun Dealer only) c006 IN0 (Gun Dealer only) write: c010-c011 foreground scroll x lo-hi (Yam Yam) c012-c013 foreground scroll y lo-hi (Yam Yam) c014 flip screen c015 Yam Yam only, maybe reset protection device c016 ROM bank selector c020-c021 foreground scroll x hi-lo (Gun Dealer) c022-c023 foreground scroll y hi-lo (Gun Dealer) I/O: read: 01 YM2203 read write: 00 YM2203 control 01 YM2203 write Interrupts: Runs in interrupt mode 0, the interrupt vectors are 0xcf (RST 08h) and 0xd7 (RST 10h) PCB: DY-90010001 CPU: Z80B Sound: YM2203C + Y3014B DAC MCU: Unknown 64 pin DIL OSC: 12MHz, 5MHz Clock measurements: Z80 CPU - 12MHz/2 YM2203 - 12MHz/8 ***************************************************************************/ #include "emu.h" #include "includes/gundealr.h" #include "cpu/z80/z80.h" #include "sound/2203intf.h" #include "screen.h" #include "speaker.h" WRITE8_MEMBER(gundealr_state::bankswitch_w) { m_mainbank->set_entry(data & 0x07); } template WRITE8_MEMBER(gundealr_state::fg_scroll_w) { m_scroll[offset] = data; m_fg_tilemap->set_scrollx(0, m_scroll[0^Xor] | ((m_scroll[1^Xor] & 0x03) << 8)); m_fg_tilemap->set_scrolly(0, m_scroll[2^Xor] | ((m_scroll[3^Xor] & 0x03) << 8)); } template WRITE8_MEMBER(gundealr_state::flipscreen_w) { machine().tilemap().set_flip_all(BIT(data, Bit) ?
