Video game Youtuber HBomberGuy, who has 300,000 subscribers on Youtube, is currently playing Donkey Kong 64 for at least 19 hours and counting on his livestream.

HBomberGuy is streaming Donkey Kong 64 in an effort to raise funds for a transgender children’s charity called Mermaids after the United Kingdom’s National Lottery suspended its lottery funding to the charity. This happened after a comedy writer named Graham Linehan told people to email the National Lottery to stop funding Mermaids.

At the time of writing, HBomberGuy has raised over USD44,000 for the charity thanks to his livestream. He has no intentions to stop playing until he achieves 101% completion, which will require at least 30 hours.
