Hi.
I've started using Boyscout in the days, but as you all propably know, the playback library that comes with it doesn't work properly onm hardware, as Channel 3 doesn't make any sound at all.
Is there anyone out there that has a solution to this, or maybe someone has made their own code for playback(I'm programming in C using Devkit Advance).
I think many would be really grateful if code working on hardware would be made public.

Yes, that would be nice! I'm using Devkitadv also with Boyscout, and no sound on channel 3 when runing on my real GBA SP!
And it's a pain in the butt, to get the Boyscout code to work in Multiboot mode. However, I did get it to work in Multiboot mode without editing the Boyscout code!
I can post what I did and my code, if you guys want?
Edit: Wow! This is my first post, since I joined here last year!

Yes, I have that problem too.. If you care to post it, that would be pretty nice =)

Oops! You DO need to edit one line of code in the Boyscout.cpp file:
| Quote: |
// Default memory to beginning of external RAM
g_nBoyScoutMemoryArea = 0x02000000;
Change to:
g_nBoyScoutMemoryArea = 0x02FA0000; |
That way, Boyscout uses that memory area for it's ram buffer, and not right over the multiboot program. Then put:
| Quote: |
| int __gba_multiboot; |
At the top off your main code file.

The EWRAM is 0x02000000-0x0203FFFF, so use g_nBoyScoutMemoryArea = 0x02020000 instead.
Is the source available for the BoyScout player, the problem with channel 3 is probably due to swapping of the wave ram banks.

source can be found here -> http://www.pidelipom.com/boyscout/
as for the memory use the provided functions instead
| Code: |
///////////////////////////////////////////////////////////////////////
// Function: BoyScoutSetMemoryArea //
// //
// Description: Sets the address to the beginning of a memory area //
// that BoyScout may use. This is basically for storing //
// pattern description for faster access times. //
// //
// Parameters: Address to the memory area beginning. //
// //
void BoyScoutSetMemoryArea(unsigned int nMemoryAddress) ///////////////
{
// Set it
g_nBoyScoutMemoryArea = nMemoryAddress;
}
// End of BoyScoutSetMemoryArea
|
You can use BoyScoutSetMemoryArea(0x02020000); after the BoyScoutInitialize(); call.
You should really malloc a buffer though.
From the BoyScout manual
| Code: |
void AgbMain(void)
{
unsigned int nBSSongSize;
// Initialize BoyScout
BoyScoutInitialize();
// Get needed song memory
nBSSongSize = BoyScoutGetNeededSongMemory((unsigned char *)SongData);
// Allocate and set BoyScout memory area
BoyScoutSetMemoryArea((unsigned int)malloc(nBSSongSize));
// Open song
BoyScoutOpenSong((unsigned char *)SongData);
// Play song and loop
BoyScoutPlaySong(1);
while(1)
{
// Wait for vertical blank
WaitForVSync();
// Update song
BoyScoutUpdateSong();
}
// This part will never be reached but just for completion
// Free memory
free((void *)BoyScoutGetMemoryArea());
}

I put together a simple program, Edited one line o code in Boyscout.cpp , included a some test music I made, and renamed some files. It also works with Multiboot but, still no sound 3. And, I got it to come out REALY small: 8.25KBs :)

They only set the waveram bank to 1 and never switch it.
from line 612:
| Code: |
// Copy waveform to bank 0
SG30L = SG30LSTEP32 | SG30LSETBANK1;
// WK add conditional define, and fix software copy
#if(USE_DMA)
DMA3Copy32((unsigned int)&g_pSound3WaveForms[4*g_nSound3PlayWaveForm], (unsigned int)&SGWRAM, 4);
#else
pSrc = (unsigned int*)&g_pSound3WaveForms[4*g_nSound3PlayWaveForm];
pDst = (unsigned int*)&SGWRAM;
pDst[0] = pSrc[0];
pDst[1] = pSrc[1];
pDst[2] = pSrc[2];
pDst[3] = pSrc[3];
#endif
}
|
You should probably insert
SG30L = SG30LSTEP32 | SG30LSETBANK0;
after the copy so the GBA actually uses the new waveram...

That's the initial wave loading, the switching is done at line 841
| Code: |
// Set to correct bank
if(g_iSound3PlayBank == 1)
SG30L = SG30LSTEP32 | SG30LSETBANK1;
else
SG30L = SG30LSTEP32 | SG30LSETBANK0;
|
and waveform updating done at 1071
| Code: |
// UPDATE SOUND3 WAVE FORM DATA //
// If a new waveform is set
if(g_aRLESound3[2].nValue != g_nSound3PlayWaveForm && g_aRLESound3[2].nValue != PATTERN_PARAMETER_EMPTY)
{
// If a valid wave form
if(g_aRLESound3[2].nValue < g_cSound3WaveForms)
{
unsigned int *pDst, *pSrc;
// Set wave form
g_nSound3PlayWaveForm = g_aRLESound3[2].nValue;
// WK add conditional define, and fix software copy
// Copy wave form to WRAM
#if(USE_DMA)
DMA3Copy32((unsigned int)&g_pSound3WaveForms[4*g_nSound3PlayWaveForm], (unsigned int)&SGWRAM, 4);
#else
pSrc = (unsigned int*)&g_pSound3WaveForms[4*g_nSound3PlayWaveForm];
pDst = (unsigned int*)&SGWRAM;
pDst[0] = pSrc[0];
pDst[1] = pSrc[1];
pDst[2] = pSrc[2];
pDst[3] = pSrc[3];
#endif
// Set current play bank
if(g_iSound3PlayBank == 1)
g_iSound3PlayBank = 0;
else
g_iSound3PlayBank = 1;
}
}

I submitted a couple of fixes to Christer just now
the problem with hardware playback is at line 875
| Code: |
SG31 = SG31FREQUENCY(canNoteFrequencies[g_anSound3Params[3]-36]) | SG31PLAYONCE;
SG31 |= SG31INIT;
SG30L |= SG30LPLAY;
|
which should read
| Code: |
SG30L |= SG30LPLAY;
SG31 = SG31FREQUENCY(canNoteFrequencies[g_anSound3Params[3]-36]) | SG31PLAYONCE;
SG31 |= SG31INIT;

that's such a horrible build system
devkitARM_r11 makes a binary of 6,528 bytes with your tune

Boyscout lib sets, sound 3 notes, step, ect... Just fine but, it does NOT set the Wave form data when on a real GBA/SP or it sets it to FF FF FF ect...!
Wintermute, your Makefile won't work for me at all! I set things right but, it just won't work!
And your BoyS example, all sounds work fine on a emulater but not the real thing, and sound 4 sounds fine on both with your example but, sound 4 only sounds good on a emulater with my example! Kinda weard... Must be DevKitAdv with the memory! :P
I also tried the code fix you said starting at line 875 but, it did'nt work.
I'm sure somebody can fix the sound 3 playback! ;)

well, the last attempt sounded like it wasn't setting the notes properly to me.

well, devkitadvance is a bit behind the times now :P

yeah, try this

#39226 - Bowser - Wed Apr 06, 2005 5:28 am
Wintermute, you did it!!! You MUST send it to the Boyscout owner! Now it's time to start making music using Boyscout!
As for your makefiles, I DID use DevkitArm with makesys but, it came up with lots of dir errors and can't find file errors! I'll try again later.
To everyone: I know this is a little bit offtopic but, I finished my BoyS test tune, download below (Right click, Save As):

Great job Wintermute, on the Boyscout Lib!!!

wintermute, I tested out your updated library and the code in my project this morning, but it made no difference to the distorted sounds at all(in multiboot at least). I will check it out properly when I come home from school and meetings tonight.

Yep! It is DevKitAdv! We need to start using DevkitArm! *Go's and Trys using DevkitArm again!* :P
And I updated my tune cause, I set the notes to lood on sound 4 in the music. :)
#39236 - SNES-lover - Wed Apr 06, 2005 10:54 am
Yep, it is DevKitAdvance I'm using, as I'm going with HAM and the HAMlib.. Maybe I'll try to go DevKitARM with the HAMlib if it's possible ;/
