@CarlPlaysWii This is quite a bit of info!
Let me see if I can break it down...
I found my issue for the MOGG alignment thanks for guide, but I'm still having the same problem for the "cannot be restored" issue and I can't seem to find a pattern.
There's still something wrong somewhere. If you're trying to import multiple songs, it ranges from being a minor annoyance to a real pain in the neck. Remove all the songs, reset cache, and then add them back one by one until you run across one that breaks, then remove it and keep adding. You should be able to find all the faulty songs this way, but depending on how many you have, it may take some time. I suggest not adding any more until you've fixed the ones that are broken.
For just Rock Band 1 songs, only the last 11 songs (start with sayitaintso) seem to be getting the problem but not the songs before?
Doesn't matter which songs they are; it can be the first 11. It's possible that the errors lie in either the folder structure or the DTAs. Check that every file is in the proper place AND the DTA is properly formatted for RB3, for every song that doesn't work.
All of Lego Rock Band doesn't work (I haven't tried Rock Band 2 yet)
If you used the old DTAs from my repo, that may be your issue.
Use the new ones from RBHP GitHub. You can better format it with MahoppianGoon's songs.dta editor and a text editor.
I haven't touched the MIDI or the MOGG files at all (except for the few that work for audio alignment) and they run smoothly when I play the individual files on my PC.
Usually, you take off exactly 3 seconds for audio adjustment, but it may vary. Since I don't own every Track Pack, I haven't tested this.
The only thing I've changed for the DTA files is the MetaFolder# within name (contentGeneration was correct to begin with) across all songs. Is there something else I should check? Should I be changing the url in midi_file as well?
If you are importing songs for RB3, there doesn't need to be a line for the MIDI file. That's only for RB2. Double check to make sure there is no extra info in your DTA that may be causing problems (i.e. double previews, pack info, etc.).
Folder numbers and total amount of songs added have nothing to do with it (I've tested it)
Shouldn't matter, anyhow.
I've found the game crashes whenever I pause then return to either the song or the music library, but runs fine when the song is completed or failed (RB3 songs works fine). This happens to all songs that I've tested. Don't know if it's just me, but it's the least of my concern.
Crashing upon returning to the song indicates a corrupt MOGG or BIK. Crashing upon returning to the library suggests to me that the
(preview # #) in the DTA may be out of range. The latter hasn't been added to the Known Issues Snippet since I have yet to run across it.
Also for future reference, how do I add multiple upgrades to a single song (ex. Pro Guitar and Keys)? And having multiple packers in my SD Card (such as both sZAE and sZBE folders) delete the latter ones is that suppose to be normal? Thanks in advance!
I personally have not tested RBHP upgrades; they are supposed to be able to work even on official DLC.
StackOverflow0x has a nice guide over at Customs Creators. Let me know if that works for you.
As for the packers, I'm not entirely sure what you're asking. Did you use
git clone or extract a ZIP from the repo into the SD card? That's not recommended; move it to a safe place on your computer's hard drive. If you're using git, then yes, using
git pull will overwrite whatever is in there. I recommend moving the DLC packers to a separate folder named "RockBandProject" or similar. If you're using a ZIP, let it overwrite the duplicate files and folders in your project directory.
I hope this answers your questions! Let me know what else you might have issues with!
