Sonic 1 music loop points

The title.


Any technique that works I will try. Please help. :lickrom:

 

I do not understand what you mean, be more specific please, Looppoints doesn't say anything.

 

Markey is right,what exactly do you mean by looppoints?

 

Song looppoints. (Will edit title)

 

You'll have to be more specific than that, do you mean as in a music format? If so what format and for what engine/console/machine and what type of loop?

 

SMPS Sonic 1 (Genesis) song loop points, loop points as in, when the song gets to the end, it will go back to a certain point in the song an continue.

 

F6 QQQQ


QQQQ is the number of bytes to jump forwards or backwards, if from 0000 to 7FFF (Positive), it'll jump forwards, if from FFFF down to 8000 (Negative), it'll jump backwards.


Example (Square brackets is the byte it jumps to):

Code:

?? ?? ?? [??] ?? ?? ?? F6 FF FA ?? ?? ?? ??

?? ?? ?? ?? ?? ?? ?? F6 00 02 ?? [??] ?? ??

You should be more specific and careful not to subconsciously leave important information out which is vital to your needs.

 

How would I find out which byte is which point in the song?

Sorry bout' that.

 

The best thing would be to tell us why you actually want to know that.

 

To make my music ports better.

 

That would depend on what game you're porting from, I'd suggest you take a look here before asking any further questions.

 

And I suggest you to read this: http://sonicresearch.org/forums/index.php?showtopic=2026


It contains a very nice part that explains how to make songs loop.
