Not aware of one. When it was ripped/released a long time ago dreamcast emulators barely existed, the gdrom hardware emulators didn't exist, and no one really cared about doing 1:1 data copies of discs in gdi format because it wasn't useful for anything other than archival purposes, which people weren't as interested in yet. The people with the gdrom disc provided it to a scene group to rip and create a self booting CDI, since that was the main way people were able to play dreamcast games at the time. The question has been asked before at assemblergames about what happened to that gdrom and I'm not sure anyone knows who wound up with it last.
The game is 100% playable though with no hiccups, so it seems the only advantage to a gdi version would be for posterity, like "this is the exact way the files were ordered on the disc sega created" and not like it would create a better working game.
