Not to my knowledge, the only thing is if it's ntsc-u, PAL, or ntsc-j.

The 1 : 16 : 03 was not cheated as far as we know. Mods did investigate it and came to the conclusion it was legit.

The keyboard rule change happened after said run, and was decided by a vote of the community. I believe the community voted that the 1 : 16 : 03 run, since done prior to said rule change, would still be considered the wr.

Chirch removed his run himself. It was not a mod.
