thanks for your playing test on real machine, I'm glad that you enjoyed with this last version.
Still have a lot of work and bugfix to do on NeoPhoenix.
I hope to find some spare time on bug fixed Rel.009 in the future.
It's very funny work on this little project for me
There aren't any cheat or god-mode.
After you complete wave 5, it cycles again back to wave 1.
The only difference is in some of the scores and the enemies get faster.

The "Insert Coin" functionality it's very simple, I read the NeoGeo ram button mapping with poll_joystick() and send the result code through hexdata var into Phoenix's hardware emulated ram and the Z80 emu do the rest.
Here's the code:
DWORD input;
// z80 emulator functions
// Reading from buttons
unsigned Z80_RDMEM (dword A)
{
hexdata = 0xff;
// $0000-$3FFF ROM
if (A < 0x4000)
return PHOENIX_ROM[A];
else
// $4000-$4FFF RAM/VRAM
if (A < 0x5000)
return (RAM[A-0x4000]);
else
if (A < 0x7000)
return (0xFF);
else
// $7000-$73FF Buttons
if (A < 0x7400)
{
// Reading from buttons port
input = poll_joystick(PORT1, READ_BIOS);
if (input & JOY_LEFT ) {
//exdata &= ~(1<<6);
hexdata &=~0x40;
}
if (input & JOY_RIGHT ) {
//hexdata &= ~(1<<5);
hexdata &=~0x20;
}
if (input & JOY_A ) {
//hexdata &= ~(1<<4); // fire
hexdata &=~0x10;
}
if (input & JOY_B ) {
//hexdata &= ~(1<<7); // shield
hexdata &=~0x80;
}
if (input & JOY_START){
//hexdata &= ~(1<<1); // 1p start
hexdata &=~0x02;
}
if (input & JOY_SELECT){
// hexdata &= ~(1<<0); // coin 1
hexdata &=~0x01;
}
return (hexdata);
}
else
if (A < 0x7800)
return (0xFF);
else
// unmapped
return (0xFF);
}
Grazie!
