I've just recently started properly ripping the first two Metroid Prime games since all the previous releases were not very satisfying. The first title is already done and will be released soon, but I've got a problem with the second one. Since I always include all beta and trailer tracks in my rips, I got my hands on the Metroid Prime 2 Echoes Bonus Disc and, playing the demo, found some compositions different from the final releases. The THPs and RSFs play just fine with vgmstream (using the latest revision), though most DSPs won't play.
Three of the DSP files are working anyway, they just sound a little off (played back at half the original tempo and with the pitch just as low):
dark.dsp
first-ruins.dsp
ridley.dsp
Those tracks were originally from Metroid Prime, so they could be some intermediate test tracks for the new DSP format. I uploaded the files with corrected pitch and tempo and included their Metroid Prime DSP counterparts. It seems that the demo files are the exact same as the left channel DSPs from the first game once they are corrected.
The other sound files are still up on the old mirror.
I'd appreciate if you could look into it and fix the track playback for one of the future releases.
I just thought it'd be useful to point out why MP2 Demo files don't currently play properly, and that, based on that information from the past, it's not likely that it'll be fixed soon. But as I said, that was awile ago. Perhaps HCS has changed his mind since then. Mouser X over and out.
Tried it with both a final and demo version track but of course didn't work since I have no idea which values are correct.
I assume the interleave value 36608 (0x8f00 for RS03 DSP) is right, but the channel coefficients are missing. I know they start at 0x20 and 0x40 in the DSP header respectively, but how do you get the decimal value for the Generic Header Creator from those?
Also, if I save the final file with the GENH, the old header is still included. Shouldn't "Header Skip" cut it?
Sorry can't help with the rest, but GENH will not alter a file in any way that will cause data loss. The reason for this is that it will allow you to get the original file back if the format is later supported in its native form (without requiring a re-rip).
Header Skip tells vgmstream (or any other plugin that offers GENH support) to skip the number of entered bytes at the start of the file. Basically, to "skip the header".
0x40 = 64
The final version DSPs now work with the GENH, albeit with quite a few clicks here and there. The demo file is still horribly garbled. The RS03 identifier (first 4 bytes) is missing there, but I took that into consideration, so that's not it. Could it be that the interleave value is different and that that's the only problem?
