Hi BEY !

A question for you concerning the sound! what do you think to do for sound FX and BGM in Galaga, or Phoenix ?
creat simply ADPCM-A sound FX? ...


recently, I found on the Net, some tech. Notes concerning the Namco Waveform Sound Generator (WSG) (used in Games like Galaga, Pacman...)

http://www.walkofmind.com/programming/pie/wsg3.htm

My question: is it compatible with other 3-channel Sound Generator, like the Neo's SSG ...

Sounds will be the final part of project. I think to play game sound with ADPCM-A sound FX takes from original game and send to NeoGeo audio chip with something like this:

if ( addr >= 0x6000 && addr <= 0x63ff && sound!=null) {
if ( RAM[addr]!=newByte ) {
RAM[addr] = newByte;
if ( newByte==143 ) Play(explosion);
if ( (newByte>101)&&(newByte<107) ) Play(laser);
if ( newByte==80 ) Play(blow);
}
}

if ( addr >= 0x6800 && addr <= 0x6bff && sound!=null ) {
if ( RAM[addr]!=newByte) {
RAM[addr] = newByte;
if ( newByte==12 ) Play(shield);
if ( newByte==2 ) Play(hitSFX);
}
}

I have to learn how to trasform .wav into ADPCM NEOGEO format and write Play() function.

Now I'm working with original Z80's Phoenix code for hack WAIT_VBLANK() and gain several ms for speed up the emulator. It's hard work, hope to find somebody who can help me....

Hi

This is my proposition concerning a Play() function. I must precise that I'm not a programmer, so you will find may be some codes error ...

I find also this Emulator ; with the audio that you use in your own code
https://github.com/mangini/phoenix-dart Phoenix Arcade Emulator for Dart => Download ZIP : audio in '.ogg' format

for example the routine to translate Original sound code to an other one is very similar

----------------------------------------------------------------------
ligne 242 to 262...
if ( addr >= 0x6000 && addr <= 0x63ff) {
if ( peekb(addr)!=newByte ) {
mem[addr] = newByte;
// sound.updateControlA((byte)newByte);
if (!isMute()) {
if ( newByte==143 ) explosionSFX.play ();
if ( (newByte>101)&&(newByte<107) ) play(laserSFX);
if ( newByte==80 ) blowSFX.play ();
}
// canvasGraphics.setFocus(true);
}
}
if ( addr >= 0x6800 && addr <= 0x6bff) {
if ( peekb(addr)!=newByte ) {
mem[ addr ] = newByte;
// sound.updateControlB((byte) newByte);
if (!isMute()){
if ( newByte==12 ) shieldSFX.play ();
if ( newByte==2 ) hitSFX.play ();
}
}

Fortunately there aren't a deadline for homebrew coding smile

Meanwhile I have made some upgrade for speed up the emulator with rom hack (I think I'll skip stars bg routine for gain microseconds) and some other emu changes.

The new Y+scroll_reg offset works on the eagles level (yBg=y+((32-(scroll_reg>>3))%32) but I miss some of boss ship yellow tile (I don't know why, maybe wrong new vram offset), I'm still working on a fix.

I have still video clear performance routine problems for eagle level, the original game don't clear old XY BG offset sprites ( like FG sprites) before scroll_reg changes because Phoenix HW uses no software up/down eagles movements but hardware with scroll_reg so I have to clean dirty pixel but code is slow and eagles going to flickering.

//Video Bg Clean before new eagles XY offset by scroll_reg hardware register
if(ScrolRefresh )
{
// write to hardware NG video 320x224 pixel 28x40 tiles
//erase_sprites 1280/32 = 40 tiles -> 2560
i=2560;
*VRAM_OFFSET=0x0800; //256=32*8
while(i--){ *VRAM_VIDEO= 0x00;}
ScrolRefresh=0;
}

39

I don't really get your offset and size calculation but fastest way to clear a sprite is to set it offscreen with a 0 tile size.

To fast clear set addr (0x8200 + sprite #) to 0x8800

That will unstick sprite, move it offscreen (line 224) and set a 0 tile size.

40

Thanks HPMAN, I will try.

Finally the scroll_reg hardware register is now emulated.
Now the eagles and Boss Ship are rightly placed in their own position like the original.

The ClearBgLayer code work but is still slow...I have to work on that..for(ii=0;ii<31;ii++) { i=31; while(i){*VRAM_OFFSET = 0x0800+0x40*ii+0x02*i; *VRAM_VIDEO= 0xFF; i--; }

I can't find the Byte Code related with Eagles and Boss Ship sound effect...
RetroIsTheOnlyFuture!

45

For who interested to argument and want a code template, I have found two solutions for ClearBgLayer routine optimization:

First, like a memcpy:i=0x0968; while(++i<0x103E){*VRAM_OFFSET = i; *VRAM_VIDEO= 0x00;}


Second more fast but more code, you can reuse it for other effect on screen:
for(ii=6;ii<32 ;ii++) { //i=31; //while(--i){*VRAM_OFFSET = 0x0800+0x40*ii+0x02*i; *VRAM_VIDEO= 0xFF;} //0x0800+off+2=0x0968 off=6 //0x0800+off+62=0x103E off=31 off=0x40*ii; *VRAM_OFFSET = 0x0800+off+2; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+4; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+6; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+8; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+10; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+12; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+14; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+16; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+18; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+20; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+22; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+24; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+26; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+28; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+30; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+32; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+34; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+36; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+38; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+40; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+42; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+44; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+46; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+48; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+50; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+52; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+54; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+56; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+58; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+60; *VRAM_VIDEO= 0xFF; *VRAM_OFFSET = 0x0800+off+62; *VRAM_VIDEO= 0xFF; }

Compiler probably going to optimize as a single statement tho, so you should add volatile.

This should be done in asm really.

This should do your thing (untested).

Could squeeze out more speed by unrolling the loop. (about 260 cycles)

49

ASM routine work fine!

Just a little fix with vram moduo set 1 after run:
__asm__ ( " move.l #0x3C0002, %%a0 \n" " move.w #0x2, 2(%%a0) \n" //vram modulo " move.w #25, %%d0 \n" //do 26 times (6-31) " move.w #0x0982, %%d1 \n" //0x0802 + 0x40*6 "0: \n" " move.w %%d1, -2(%%a0) \n" //sets addr " add.w #0x40, %%d1 \n" //add 0x40 for next ".rept 31 \n" " move.w #0xff, (%%a0) \n" //write data // " nop \n" //uncomment if writing is too fast for LSPC ".endr \n" " dbra %%d0, 0b \n" //loop " move.l #0x3C0002, %%a0 \n" " move.w #0x1, 2(%%a0) \n" //vram modulo :::"d0","d1","a0" );

If you have a way to run it on AES with the Development/Debug BIOS (typically via MESS, UME, FBA, or whatnot), it might bring up an error message. (Granted, you'd want to have a listing file that shows where all the code is assembled to, in order to figure out where the actual problem is; I'm not sure how you'd do that with the NeoDev kit, though.)

Thx freem, I'll work on it.

Hello

So i test it on my neo geo CD front
so i think it's more faster than you other version but i could be more...

so i see a lot of sprite bug
some animation not be present (may be it's too slow)
but at the 3 and 4 level the same bird was present in lot of part of the screen

in the introduction i have two music who begin in some different time

the start botton was probably echanged with the select botton

Today, I burned your latest CD and played the game on my top-loader NGCD + Sony PVM CRT. The game runs quite slow but it is playable and I had fun paying it for a whilewink
I have seen some sprite glitches when an enemy explodes (first level) and when a "bird" enemy is moving (third level).

Is there any kind of cheat available for a level selection or god-mode?

How did you made the "Insert Coin" functionality? I would like to add it to my game too - would you maybe provide the code of it?

57

Hi NeoHomeBrew,
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 oui

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.
Phoenix FAQ: http://www.gamefaqs.com/arcade/564009-phoenix/faqs/26630


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); }

Hi BEY,

thanks for your answer and the code. Then I have to fight through the 5 levels to see the boss wink

Unfortunately, I can't use the code for my project but it explains a lot. I think I need something in ASM for a real
"coin insert detection" which will work on a real MVS arcade machine. When I have found something
I will post it in my thread.

59

I didn't play along with it but coinage is handled mostly by the bios on itself, with a few functions related to it available.
See the official doc.

Hi all,
time to rewrite some C function to ASM 68K in NEOPHOENIX for speed up the game smile

I'm a total newbie in asm 68K so forgive me for any stupid questions, here's the first one:
//C code: unsigned short code,A; int x,y,yBg,k; yBg=(A&0x1F)+k *VRAM_OFFSET = 0x0800 + (x<<6) + (yBg<<1); *VRAM_VIDEO = 512+code; *VRAM_VIDEO = ((code >> 5)| 0x00 ) << 3; //ASM code: __asm__( "move.w #0x0800, %%d1 \n" // "movw %0, %%d0 \n" // load x from C "lsl.w #0x6, %%d0 \n" //-- x<<6 "add.w %%d0, %%d1 \n" // 0x0800+(x<<6) "movw %1, %%d0 \n" // load y=A & 0x1F from C "andi.w #0x001f, %%d0 \n" // y=(A&0x1F) "movw %2, %%d2 \n" //-- Load k from C in d2 "add.w %%d2, %%d0 \n" // yBg=y+k "lsl.w #0x1, %%d0 \n" // yBg<<1 "add.w %%d0, %%d1 \n" // 0x0800+(x<<6)+(yBg<<1) "move.w %%d1, (0x3C0000) \n" // write data to VRAM_OFFSET "move.w %3, %%d0 \n" // load code from C "move.w %%d0, %%d1 \n" // Backup code into d1 "add.w #0x200, %%d0 \n" // 512+code "move.w %%d0, (0x3C0002) \n" // VRAM_VIDEO in a0 *VRAM_VIDEO = 512+code "and.w #0xffe0, %%d1 \n" "lsl.w #0x3, %%d1 \n" "move.w %%d1, (0x3C0002) \n" // *VRAM_VIDEO VRAM_VIDEO in a0 ((code >> 5) | 0x00 ) << 8 : :"a"(x), "a"(A), "a"(k), "a" (code) :"d0" ,"d1", "d2" );
This code work fine.
The question is: How can I optimize the ASM code? It's possible?

Thanks
