Unofficial IPF database

Is there any database with unofficial IPFs?

Right now I see plenty of IPFs here and there but apart from No-Intro and TOSEC unofficial dat I don't see any sorted and organized source. Plenty of IPFs are still not in above two databases.

I'm pretty sure Crashdisk has a "few" unofficial ipfs lined up for next TOSEC release, whenever that may be.

I'm sure too

Would be good to also know that's might be wrong with certain unofficial dumps and why official one has not been made.

Example:

Deep Core - multisyncs, weak bit protection, not supported in IPF officially
Dungeon Master - weak bit protection, no official IPF since this cannot be write back to disk correctly
Nitro - custom MFM format without any data verify
Traps'n'Treasures - lack of good dumps
Ultimate Pinball Quest - all versions had modified hiscore
Robin Hood: Legend Quest - why ?
ATR: All Terrain Racing - the same situation (but my copy was from new disks)

Yeah, SPS only deals with pristine disks.

Unfortunately that's just impossible in some cases.
Take Iceball (ipf in the Zone) for instance, the disk has to be write enabled to even load the game.
I seriously doubt we'll ever see a "virgin" disk of this rather obscure game.
