move SDI tune to different memory location
Hi!
I made a tune in SDI 1.8 and I want it to start at $b600 rather than $1000. I tried changing the start address in BM TASS. But the tune doesn't play at the new location.
What else do I need to change?
Anyone can help?
thx

You can do 2 or 3 things:
Assemble to disk (arrow 5)
or put an .offs $xxxx after the *=$b100
to assemble to other memory (the code will still
be relocated to $b100, but you can now save it from f.ex 1000-xxxx)
or use the SDI packer, where you can change the address

I tried saving the tune with <- 5, but it didn't work as expected.
I put the .offs at the start of the source. Do I have to set the offset AFTER *=$whatever ?
Didn't know that there was a SDI Packer. I'll check it out...
Thanks for your help! |

.offs $xxxx should be put right after *=$b100
The packer packs the dumped files (with " name") with space in front of name.

Hey, thank you, rambones!
I finally managed to play the music from $b800! :)
I used the .offs method to save the tune from $1800-$2400 and then loaded it from $b800-$c400 in a monitor.
The "assemble to file" function in BM TASS doesn't seem to work right. The object file is always larger than the memory area used when assembling to memory.

Try the packer, see what it can do. |

assemble to file will fail if you have more than one *=. disk access is much more sequencial than ram access. |

Ah, ok. That explains why it didn't work. There are two *= in the file I assembled. |

there is a relocator in the packer. I don't understand, why so much explainations ? Dump the file, load to packer and change the startaddress... I always do that because I want to put the name of the song after 2 jmp's :) |

You can use the SDI packer to relocate a tune. But the packer uses $7de8-$ffff and I wanted my tune to start at $b600. So it didn't work with the packer. |

@Henne:
There's 2 solutions:
solution 1:
-----------
(Lets assume your tune range is $1000-$2140 packed)
1) Dump, assemble and save the tune to $1000-$2140
2) Load and run the SDI-Relocator:
SDI Relocator V1.04
This tool requires Action Replay to be able to save
under ROM (a000-c000 and d000-ffff), but there's an manual method aswell..
3) Select your tune to relocate and press return.
Set relocate adress with + and - and press return to save.
4) If you dont have Action Replay:
Save memory 1000-2140 (this memory area contains the relocated player + data) and change the load adress
for this file to the relocation adress you wanted.
(You can also use vice monitor to do this )
Solution 2:
-----------
Conver the player source to pc text from turboassembler
using the write to sequntial file command.
Convert that file to pc-text mode and use it
with turboassembler v1.45 (singular crew) for pc.
To use a dumped tune: convert the dump to pc-text format
and use '.include yourtune.txt' in the player source.
Hope that works.
Solution 1 worked for me with sdi v1.8
