I believe this was asked in the past following the removal, but I feel it needs to be reviewed: why were the 1CC categories removed for this game and for TMNT arcade?

These were removed and consolidated onto the Any% board, to be represented with 1cc "yes or no" on Any% runs. This was done when all runs disappeared when one of the mods took it upon himself to change what had been known as separate Any% and 1CC categories, and changed the understanding of Any% to REQUIRE 1cc and call anything else "credit feeding". Long story short, recovered all any% runs, and had runs that were 1cc represented with a simple "yes or no" on the any% board to make things more organized.
