Dogway, the .ini files are named after the ID Nintendo themselves assigned (essentially an UUID for GC and Wii games). The "fluff" description is info hardcoded into the ISO or disc image. That's the field game developers set. It was never meant to be read by ordinary users; it was an internal reference for their use only. Games in Nintendo systems had these ASCII fields frequently (they're present for GB, GBC, and GBA games) but they rarely were displayed to the player, so HAL got away with things like calling Kirby Epic Yarn "fluff".
These names were generated automatically iirc by Dolphin during the initial creation of .ini files. Given the volume of .ini files present, it would be unreasonable to ask people to go through them all and manually change "inaccurate" names.
If you want to go to the .ini file for a specific game you have, the easiest way is to just right-click the game in Dolphin, go to Properties, and hit the Edit Config button.
