The Splatterhouse record belongs to a Japanese, and it's about 5 times higher then the Twinf*cks record. As always they ignore Japanese records, in this case its because they consider the Japanese record to be exploiting and not legit. Which is just rolf. The Japanese record was attained because the game has an interesting feature, if you let timer run down a double-ko with the final boss is possible, meaning you get the huge bonus for killing him, but then go back to the start of the stage. Repeat, though there is a limit as life extends are finite.
