Better late than never: Twin Galaxies has just verified my kill screen run on NES Donkey Kong! It is listed under a new variation called Fastest Completion (kill screen), where I have posted a "blazing" time of 5 hours 44 minutes. :)
Making this long affair into a "speed run" allows me and future kill screen gamers to be recognized for having reached the kill screen, without having to worry about points as they play. Special thanks to TGI referee Tim Stodden for his help in creating this variation. Without it, there would have been no way for me to submit this run to the record books.
