MAMEWorld Forums - EmuChat - About hexa sound 'clicks'

Hi all,

First of all I don't know if it may be useful regard mame code itself, but in my java emulator I've resolved the sound clicking in this way:

Write Proc:
----------

Code:


        .
        .

        // Sound: AY8910_Write
        else if ((addr == 0xD000) || (addr == 0xD001))
        {
            if (addr == 0xD000)
                last_d000_val = val & 255;
            else
                last_d001_val = val & 255;
            
            ay8910.write (addr - 0xD000, val & 255);
        }

Read Proc:
---------

Code:


        .
        .
        // Inputs
        else if (addr == 0xD001)
        {
            if ((last_d000_val == 0x0E) && (last_d001_val == 0x3F))
            {
                int val = 255;

                // 1P - Up
                if (hexaPanel.keyBuf [KeyEvent.VK_DOWN])
                    val &= ~1;

                // 1P - Down
                if (hexaPanel.keyBuf [KeyEvent.VK_DOWN])
                    val &= ~2;

                // 1P - Left
                if (hexaPanel.keyBuf [KeyEvent.VK_LEFT])
                    val &= ~4;

                // 1P - Right
                if (hexaPanel.keyBuf [KeyEvent.VK_RIGHT])
                    val &= ~8;

                // 1P - Button 1
                if (hexaPanel.keyBuf [KeyEvent.VK_A])
                    val &= ~16;

                // 1P - Start
                if (hexaPanel.keyBuf [KeyEvent.VK_1])
                    val &= ~32;

                // 1P - Coin
                if (hexaPanel.keyBuf [KeyEvent.VK_5])
                    val &= ~64;

                // 1P - Button 2
                if (hexaPanel.keyBuf [KeyEvent.VK_S])
                    val &= ~128;

                return (val);
            }

            return (dipswitches);
        }

I suppose that it isn't the correct way to handle this, anyway I hope it can be useful.

Regards.
