SID2TIA driver ported to bB

[+batari]

Here is a driver written in bB that can play music generated from SID2TIA in your bB programs. Make sure you include all of the relevant parts of the attached .bas file (that is, all of it except for the stuff in vblank, which is just intended to display something on the screen while trying out your music files.)

 

One issue is that SID2TIA produces an output file (tsmsong.h) with a hard-coded ORG, so I hex-edited SID2TIA.EXE to comment out this line because it doesn't work with bB (and a hard-coded ORG is too limiting, anyway.)

 

The original SID2TIA can be found here.

 

You must also use the attached music.h as the original format didn't work with bB (another hard-coded ORG.) The version I am attaching will work with bB and is also reverse-compatible with assembly programs requiring the old music.h.

Looks cool. I'll try it out later.

[yuppicide]

Wow. Freakin awesome. Thanks!

 

What do I use to compile or whatever now? I've been using "dasm tsm2.s -f3 -ofilename.bin", but unsure what to do here..

Just create the tsmsong.h file using SID2TIA and build the tsm2.bas with bB.

 

Or, take the contents of tsm2.bas and integrate it into your bB game you need everything but the vblank stuff.

[yuppicide]

Oh.. *smacks forehead* duh.

 

I'll try it out shortly.

 

So, if knows where to correctly put the music if I create it with bB?

 

If I stick it in myself, can I stick it anywhere?

 

For example, my current game was 8K, but I ran into some space issues so I had to bump it to 16k, which leaves bank 3 completely empty. Bank 1 has 183 bytes, bank 2 has 1849 but the game isn't finished so I need more stuff to go here, and the last bank bB stores stuff in so it only has 1433 bytes left.

Yes, you can put it anywhere, provided some conditions are met.

 

The following should go at or near the beginning of your code (at a minimum):

  include music.h
 set smartbranching on
 dim tempoCount=a
 const songendlo=<.songend
 const songendhi=>.songend
 dim soundPointerlo=soundPointer
 dim soundPointerhi=soundPointer+1

In the above example, one variable is dimmed as "a" but it could be any free variable you have.

 

The rest of the code below all needs to go in the same bank, but it can go in any bank.

 

This code initializes the music to the beginning. Do not call it every frame but only at the beginning of your program or at the end of your music so it will repeat. Keep the lines exactly as they appear below, except you may change the variable used for sdata (the example below uses "b" but note that sdata will also use the next variable "c.")

  rem THE FOLLOWING LINES MUST NOT BE BROKEN UP
 sdata soundPointer=b
end
 goto songend
 inline tsmsong.h
songend
 rem END OF UNBROKEN LINES

 rem this is to get past the goto songend and trick the sdata statement
 rem to point to the music file
 temp1=sread(soundPointer)
 temp1=sread(soundPointer)
 temp1=sread(soundPointer)

 

This code must be called in every frame you want music:

  tempoCount=tempoCount+1
 temp1=tempoCount^#TEMPODELAY
 if temp1<>0 then musicdone
 tempoCount=temp1

 temp1=getsound(0)
 temp1=getsound(1)
 rem return value is of no consequence
musicdone

 

This is a check to see if the music is done. In tsm2.bas, it jumps to the sdata statement above so it can repeat your music. It could also be used to stop the music.)

  if soundPointerlo=songendlo && soundPointerhi=songendhi then restartmusic

 

The functions and data statements below must be placed in the same bank (change audvol if you wish the volume to be less than 15.) In a bankswitched game, I'd recommend using "return thisbank" below.

  function getsound
 temp2=sread(soundPointer)
 if temp2=0 then AUDV0[temp1]=0:goto silence
 AUDF0[temp1]=temp2
 temp2=temp2/32
 AUDC0[temp1]=soundTypeArray[temp2]
 AUDV0[temp1]=audvol[temp1]
silence
 return

 data soundTypeArray
 4,6,7,8,15,12,1,3
end

 data audvol
 15,15
end

I'm trying it now for the first time and can't get anything to compile. Well, actually compilation completes.. just doesn't do anything.

 

I am using vBB.

 

I copied the new music.h to the includes directory. Not sure where to put my tsmsong.h file, so I put it in the includes directory and also the directory where I store the games I made.

 

I copied tsm2.bas into the directory where I store the games I made.

 

I set the romsize to 4k and get this:

The song in question works fine when I compile with normal SID2TIA and I played it.

This means that your tsmsong.h is too large to fit into 4k with the kernel and driver. SID2TIA thinks it has around 3.5k and it does when using the tsm2.s assembly file, but it does not have that much space in a 4k bB game.

 

To reduce the song size, you might try increasing the value in the "Resolution" box to something like 4 or 8. Apparently with 4, you get up to 2 minutes of playback and 8 should give you 4 minutes. You may lose some accuracy in the song but often you don't.

 

Regardless, I expect that it should work in the first bank of an 8k game. I believe your problem with 8k is that your "include music.h" is not in the first line of code and is being ignored.

You're absolutely right. Here's an updated SID2TIA 1.6.3 package where I moved the ORG from the tool into the driver

[yuppicide]

The song I have is not that long.

 

Moving the set romsize 8k made the program compile just fine, but I get no sound totally though now though. Just a black screen.

 

Where am I supposed to put tsmsong.h file?

 

I've included my two files here..

Here's an updated SID2TIA 1.6.4 package where I removed the write protection from the "Frames" edit control when generating TSM2 output. It still defaults and resets to 3.5K though

[yuppicide]

It is. I removed all the stuff in it so it's just

 

vblank
return thisbank

 

I just wanna go your demo program working before I go messing with my real program.

Actually, it isn't unless you place "bank 2" before it. Either do that or remove vblank altogether.

[yuppicide]

I do have bank 2 in my code. You said that one part of the codes needs to come in the beginning and the rest can all go in another bank if I wanted.. so I moved it all to bank 2.

Oh, I see it now. The code doesn't necessarily have to be contiguous, but everything before vblank does need to be in the same bank.

[yuppicide]

I put this in bank 1:

 

 include music.h
 set smartbranching on
 dim tempoCount=a
 const songendlo=<.songend
 const songendhi=>.songend
 dim soundPointerlo=soundPointer
 dim soundPointerhi=soundPointer+1

 

Everything else in bank2. That's how it would be in my real game also, except everything else in bank 3.

Unfortunately that won't work. You need to put the code to read the music in the same bank as the music itself. If the code to read it is in another bank than your game code, you will need to access music with an inter-bank goto or gosub once per frame.

[yuppicide]

But that code below in bank 1 doesn't read anything.. it just includes music.h and dims things.

 

I can't stick that stuff in bank 3 can I? I don't think so..

I see tsmsong.h in there as well as the dims. tsmsong.h is the music data which needs to be in the same bank as the code that reads it.

 

Here is something that should compile:
