Once in a blue moon, I'll get this rare glitch when playing the PS1 version on an emulator. Enemy body parts, or doors, or objects will randomly appear stuck to a character. I was recording a run that was going really well, and then...well, the glitch decided to happen, ending with a mass of Trimorph parts instant killing my character, and the run.
Going to try a run again tomorrow on the PC version; will try a PS1 run again in a couple of days when I have more time, but I'll probably hold off on that version a bit until I figure out the best way to capture and record video from my PS3 so I can run my physical copy of the game.
On another note, if anyone knows what may be causing this glitch to occur, please let me know, I would love to fix it because while it's only happened three times to me total across my entire time playing it on an emulator, it really sucks when it happens and can pretty much ruin the game.
This same thing happened on this guy's walkthrough after he walked out of the shuttle bay corridor @ 22:10
He explains how to deal with that, but it apparrently forces you to save the game and reload that save again. And if this is random thing, it's going to be tought times with the speedrunning, meaning that if this happens, the run in dead. Or at least No Saves-run is dead at that point.
