It ain’t listed because it ain’t mainline (and we also don’t have the space to do it either), Deltarune isn’t finished yet, and fan games ain’t included. I would make a records stream in order to fix this problem.
HEY SPINEL... I HAVE A REALLY GOOD QUESTION... SO IF YOU GUYS ACCEPT UNDERTALE SPEEDRUNS WHY NOT DELTA RUNE ONES AND SINCE I HAVE UNDERTALE YELLOW CAN I HAVE A SPEEDRUN RECORD ON IT?... WHY CANT I BE LISTED AS ONE AS WELL? I WOULD LOVE TO PRACTICE AND TO HAVE A SPEEDRUN RECORD ON THIS UNDERTALE STREAM PLAYING UNDERTALE YELLOW!
