I've never seen a video of the cameo battle in ToD2. Is there not one on YouTube, or at least screenshots of it somewhere?
Ah, they're separate battles.
Removing broken links.
I noticed some inconsistency with how the PSP cameo characters were being listed on arte pages and removed the ones that were separated into PS2 and PSP, but now I feel those were more correct. Should I change them back? The order should be: playable characters, story bosses, optional bosses, cameo characters, generic enemies.
I honestly answered my own question and fixed everything.
