Single Joystick control of Battle Zone?

[dgame]

EDIT: Dawgz Rule posted an easier solution below. I included the full solution in my post below.


Hi,

I was admiring rockyrocket's  Tempest(ish) caberet cab http://forum.arcadecontrols.com/index.php/topic,123455.0

Since he put on Battle Zone stickers and only has one joystick I wanted to recommend the single joystick control Battle Zone MAME patch.

I read his thread again and it seems he is using the AAE Emulator which I think still has the single joystick hack.

But now I want to have the Battle Zone single stick hack in my MAME setup.

EDIT: Dawgz Rule posted an easier solution below. I included the full solution in my post below.

I found the 141u1 patch here http://forum.arcadecontrols.com/index.php/topic,108813.msg1155082.html but it does not work with 147 sources as things are different now.

I manually put the changes into the new source code.

The input_port_read() no longer exists in MAME. More on this here: http://mame.dorando.at/svn/?start=16119

I tried to use the ioport function but don't quite understand how to translate the changes into the new MAME format.


This is what the patch adds/changes in the Battle Zone code:

mame/audio/bzone.c:

Code: [Select]

/* Translation table for one-joystick emulation */
static UINT8 one_joy_trans[] =
{
0x00,0x0A,0x05,0x00,0x06,0x02,0x04,0x00,
0x09,0x08,0x01,0x00,0x00,0x00,0x00,0x00
};

static READ8_DEVICE_HANDLER( bzone_IN3_r )
{
int res = input_port_read(device->machine, "IN3");
if (input_port_read(device->machine, "SELECT") == 1)
res |= one_joy_trans[input_port_read(device->machine, "FAKE") & 0x0f];
return res;
}

static const pokey_interface bzone_pokey_interface =
{
{ DEVCB_NULL },
DEVCB_HANDLER(bzone_IN3_r)
};
mame/drivers/bzone.c:

Code: [Select]

static INPUT_PORTS_START( bzone )
BZONEIN0
BZONEDSW0
BZONEDSW1

PORT_START("IN3")
PORT_BIT( 0x01, IP_ACTIVE_HIGH, IPT_JOYSTICKRIGHT_DOWN ) PORT_2WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x00)
PORT_BIT( 0x02, IP_ACTIVE_HIGH, IPT_JOYSTICKRIGHT_UP ) PORT_2WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x00)
PORT_BIT( 0x04, IP_ACTIVE_HIGH, IPT_JOYSTICKLEFT_DOWN ) PORT_2WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x00)
PORT_BIT( 0x08, IP_ACTIVE_HIGH, IPT_JOYSTICKLEFT_UP ) PORT_2WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x00)
PORT_BIT( 0x10, IP_ACTIVE_HIGH, IPT_BUTTON1 )
PORT_BIT( 0x20, IP_ACTIVE_HIGH, IPT_START1 )
PORT_BIT( 0x40, IP_ACTIVE_HIGH, IPT_START2 )
PORT_BIT( 0x80, IP_ACTIVE_HIGH, IPT_UNUSED )

PORT_START("SELECT")
    PORT_CONFNAME( 0x01, 0x00, "Controller Type" )
    PORT_CONFSETTING(    0x00, "Real" )
    PORT_CONFSETTING(    0x01, "8-way Joystick" )

PORT_START("FAKE")
PORT_BIT( 0x01, IP_ACTIVE_HIGH, IPT_JOYSTICK_UP ) PORT_8WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x01)
PORT_BIT( 0x02, IP_ACTIVE_HIGH, IPT_JOYSTICK_DOWN ) PORT_8WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x01)
PORT_BIT( 0x04, IP_ACTIVE_HIGH, IPT_JOYSTICK_LEFT ) PORT_8WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x01)
PORT_BIT( 0x08, IP_ACTIVE_HIGH, IPT_JOYSTICK_RIGHT ) PORT_8WAY PORT_CONDITION("SELECT",0x01,EQUALS,0x01)

BZONEADJ
INPUT_PORTS_END

Can this single stick Battle Zone hack be made to work with current MAME?

Thanks!

No clue about the single stick hack but you can modify the cfg file to do the same.  Here is what worked for me.....

Code: [Select]

<input>
            <port tag="IN3" type="P1_JOYSTICKRIGHT_DOWN" mask="1" defvalue="0">
                <newseq type="standard">
                    KEYCODE_RIGHT OR KEYCODE_DOWN
                </newseq>
            </port>
            <port tag="IN3" type="P1_JOYSTICKRIGHT_UP" mask="2" defvalue="0">
                <newseq type="standard">
                    KEYCODE_LEFT OR KEYCODE_UP
                </newseq>
            </port>
            <port tag="IN3" type="P1_JOYSTICKLEFT_DOWN" mask="4" defvalue="0">
                <newseq type="standard">
                    KEYCODE_LEFT OR KEYCODE_DOWN
                </newseq>
            </port>
            <port tag="IN3" type="P1_JOYSTICKLEFT_UP" mask="8" defvalue="0">
                <newseq type="standard">
                    KEYCODE_RIGHT OR KEYCODE_UP
                </newseq>
            </port>
        </input>

Thank you Dawgz Rule,

That did it!

I set it up for P1 Joystick or Keyboard input and here is the bzone.cfg:

Code: [Select]

<?xml version="1.0"?>
<!-- This file is autogenerated; comments and unknown tags will be stripped -->
<mameconfig version="10">
    <system name="bzone">
        <counters>
            <coins index="0" number="24" />
        </counters>
        <input>
            <port tag=":IN3" type="P1_JOYSTICKRIGHT_DOWN" mask="1" defvalue="0">
                <newseq type="standard">
                    JOYCODE_1_XAXIS_RIGHT_SWITCH OR JOYCODE_1_YAXIS_DOWN_SWITCH OR KEYCODE_RIGHT OR KEYCODE_DOWN
                </newseq>
            </port>
            <port tag=":IN3" type="P1_JOYSTICKRIGHT_UP" mask="2" defvalue="0">
                <newseq type="standard">
                    JOYCODE_1_XAXIS_LEFT_SWITCH OR JOYCODE_1_YAXIS_UP_SWITCH OR KEYCODE_LEFT OR KEYCODE_UP
                </newseq>
            </port>
            <port tag=":IN3" type="P1_JOYSTICKLEFT_DOWN" mask="4" defvalue="0">
                <newseq type="standard">
                    JOYCODE_1_XAXIS_LEFT_SWITCH OR JOYCODE_1_YAXIS_DOWN_SWITCH OR KEYCODE_LEFT OR KEYCODE_DOWN
                </newseq>
            </port>
            <port tag=":IN3" type="P1_JOYSTICKLEFT_UP" mask="8" defvalue="0">
                <newseq type="standard">
                    JOYCODE_1_XAXIS_RIGHT_SWITCH OR JOYCODE_1_YAXIS_UP_SWITCH OR KEYCODE_RIGHT OR KEYCODE_UP
                </newseq>
            </port>
        </input>
    </system>
</mameconfig>
This enables the tank in Battle Zone to be controlled using a single joystick or the keyboard arrow keys.

Looks very interesting I will have to give this a try.

Good to hear.  Took a little bit of time to figure out with a pad and paper but it was well worth it.  Enjoy.
