Instructions: Get the file at nand:/data/<console-unique>/sysdata/0001000f/00000000 (only available on FW 9.6, thus only available with a hardmod or on EmuNAND). Copy this to some directory on your PC together with seedconv.exe. Then just drag and drop 00000000 (or multiple different 00000000 files) onto seedconv.exe, and a working seeddb.bin should automagically be generated. If multiple files are used, the seeddb.bin will contain all unique seeds from all files. If you drag and drop one or multiple seeddb.bin files (rename them first, must not be called 'seeddb.bin'!), the unique seeds from them will also get added to the newly generated seeddb.bin file. This works also when drag and dropping alongside one or multiple 00000000 files.

Also, no seeddb.bin releases in this thread, please, as I fear that won't go well with GBAtemp rules. Share that stuff somewhere else . The game specific seeds, by the way, are not console unique, as confirmed by Shadowtrance. However, your 00000000 file may be, so be careful. ... and before I forget about it, thanks go to everyone who helped solving this mystery, including @Shadowtrance, @mixups, @key1340 and @k8099.
