Help with convert prg to sid
Hello!
I have made some tunes in Cybertracker, and want help to convert them to sid.
Shall I convert the prg-file before i crunch it to basic?

If it's a singlespeed tune and you're on Windows, just save the tune from memory to disk and export it to your harddrive. Mind that you mustn pack the tune with a packer or make it executable. Just save the Tune ($1000 - $2000 i assume).
Then get SidEdit and use it to convert the .prg file to .sid. Voila.

Make sure you saved just the tune, not any irq's for playing the tune or basic headers. Then Make sure you enter the correct values for initAddress and playAddress. |

First, i compose the tune in Cybertracker.
Then i use the executablemaker to make it executable.
I must load the file with ,8,1 and start the tune with sys 18096. (that is $46b0)
In sidedit i have tried to enter $46b0 for the playadress.
But what is the initadress?
I can nothing about machinecode. I only compose :)

I've just took a look at that executable maker. It saves the tune with a player routine that gets called at $46b0. This isnt the actual tune, but just a piece of machine code to display some screen and play the music in an irq. You cant use that address for Sidedit. I'm looking around the code to find the proper play and init, but i'm at work right now.

I'm sorry but i cant seem to figure out where the init and play calls are in this mess of a code.
I'm sure someone here knows more about the cybertracker format than me. I can try to look into it later on after work if no one else has come up with some information until then.
Sorry.

I looked at it..
It seems the player is dependant on poking 1 and 2 into a byte, from outside the irq, at certain times, to play anything. this is really shit..
the init/playhandler is self modifying.. argh!

So it is impossible to convert it to sid?
Is it more possible to convert it before I make it executable?
I will send you a tune rambones, and you can try to convert it?

If all else fails, you can try asking Cyberbrain for help. Him being the person who made Cybertracker. |

there's plenty of cybertracker tunes in hvsc, but i have no idea who is responsible for ripping them. nonetheless, i assume that conversion is doable. |

Cybertracker_exe parameters:
PSID (preferable)
init 53A2
play 53E2
RSID (if PSID fails)
init 46B0
using ctpacker is probably better than making a PSID out of an executable ct, which adds unneded code anyway. Just use ctpacker.exe (rtfm!)

The .sid file created is the old version 1, just edit it in sidedit to make it a sid v2. |

THANX Ian and Ram!
But if I want to rip the orginaltunes before executable and before packing.
What is the Init and playadress then?
I will send you a tune before making it executable Rambones,
Thanx again!

I did it!
It worked to convert a tune with
PSID (preferable)
init 53A2
play 53E2
Thanx!

I have made a new sidtune today, now a sidfile.
I am missing a function on this forum, that allow users to upload their sidfiles.
It would be nice to get some feedback from the sids we make.
Greetings from Sweden!

Nono, you can easily upload sids here!
Create a release, and upload the file, fill the release credits, done!
Be sure to send all the sids to hvsc@c64.org, and we will include them in update #51. (#50 is closed now, coming very soon) |

Thanx Ram!
I have uploaded 2 sids now, but the comments are no good :)
I forgot to tell that I am no professional, but i am proud to get some "noice" from the sid 8580 anyway :)
I have always liked the sound of the sidchip.

SIDs playing to slow? Did you use multispeed, or made an NTSC tune? :D |

In sidplayer on the pc it works in the right speed.
It is just in the sidplayer on the 64, that it is to slow.
Very strange!
