We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Dragon Sword — The entry claims the game features 'full 3D models on pre-rendered backgrounds', but the game uses 3D models on 3D-rendered backgrounds (not pre-rendered static images); the backgrounds are dynamically rendered in 3D.
Double Blades — Only the first Ninja Gaiden was ported to the SNES as part of the 'Ninja Gaiden Trilogy' compilation in 1995, which included all three NES games with minor enhancements—not a separate SNES version of the entire trilogy.
