Game Name?

Before testing, all games listed below were advertised as redumps and were CRC verified as redumps:

1. Dragon Drive, 2. Generation of Chaos Exceed, 3. Kidou Senshi Gundam - Senshitachi no Kiseki, 4. Mutsu to Nohohon and 5. Gakuen Toshi Vara Noir Roses cannot be extracted and repacked into a new GCM. Regardless of whether files are unadulterated or not, the issue persists upon loading it in Dolphin. Trying to play the game or go into a new game will hardlock. The error is in the following format, but between games, the filestart and line numbers are different:

DVDPrepareStreamAsync(): Specified start address (filestart(0xabcdefg) + offset(0x0)) is not 32KB aligned in "dvdfs.c" on line xxxx

Because Japanese Gamecube games are not well documented, there is a high probability that other games not listed above also suffer from the same issue.

Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too.
