The first two episodes of The King of Fighters 3D anime can be viewed on YouTube. The episodes are in Japanese but have English language subtitles.
Tried watching and just remembered the last promo for King of Fighters called Another Day. We were spoiled in PS2 days Production I.G compared to this one is laughable. This ONA Original Net Animation, DVD quality though, promo came with preorder
Best Quality I could find with Japanese Voice all 4 episodes
