I've been studying for a future speedrun andthe thing is this, the current WR in the mission SAY HELLO TO MY LITTLE FRIEND doors open inwards. But, the doors in other speedruns open outwards. Now, this is not a bug or a hack. I haven't seen any answers in any other place so I keept diggin

If you play with Direct3D the doors in this mission open OUTWARDS and if you play with OPENGL open INWARDS.

I'm sure this will help alot of people in the future. I'm not really sure if OPENGL will crash more or less. But if you want to use a route where the doors open inwards in the configuration you will need to use openGL

PD: this is the only way I found to open the door inwards, if there is any other I think it would be helpful for me and/or other people!
