Sequence files format(s) ?

Post by Squaresoft74 » December 1st, 2018, 12:18 am

Hi,

Is there any doc about the different revisions of the PsyQ sequences format ?

I was trying to make a psf rip of some game and noticed that the driver i'm using doesn't have the expected effect when it comes to set the reverb type/depth.
(It works fine for some other game i ripped).

Could it be set from the .seq file itself since i do get depth change when patching offset 0x12 of the sequence ?
(using another driver for that test).

Is "mid2seq" (or whatever it was called) that was used to create .seq file available somewhere ?

Thank you. :)

the File format.pdf file from the PSY-Q SDK is not very verbose on this format, here is the description

Code: Select all

SEQ Format:
ID (SEQp)			4 bytes
Version				4 bytes
Resolution of quarter note	2 bytes
Tempo				3 bytes
Rhythm				3 bytes
Score data			Any
End of SEQ			3 bytes

Thanks Orion_ but i already have this from the 4.6/4.7 file format pdf files.
Hence i was wondering if there were change from older versions that the game i'm trying to rip could possibly use.

After examining all .seq and checking against no$psx SPU's I/O Map, i'm confirming depth is set from offset 0x12 for this game.

old seq.PNG
(2.7 KiB) Not downloaded yet
Also i come into looping issue when using generic driver to rip some PSF.
Either they won't loop or they'll loop wrong ( from the very beginning of the sequences).
Using a driver from older game solves the issue but still, i can't find any information about different SEQ revisions:
