Like most buggy video games from the '90s, Paper Mario has some bugs that cause BSODs. This TAS demonstrates one of these bugs. Enjoy :)

CasualPokePlayer: Replacing movie file as requested in DMs.

feos: Congrats on finding and pulling this off!
Unfortunately we can't publish this or even sent to Playground, because it abuses an emulation bug that is actually dangerous to users. A movie that escapes the sandbox and executes arbitrary code on the host can do really nasty things without the user having any idea. I didn't even dare run this on my actual OS, I created a Win10 VM, and it did give a BSOD indeed.
Now while I don't suspect the authors in installing viruses on my machine with this movie, if we open the doors for this kind of content, at some point someone may do that, and not everyone is conscious enough to only run it on a virtual machine. We can't risk damaging our users' computers.
Rejecting.

Wait, the TAS actually crashes the (Windows) system? The BSOD wasn't fake like I first thought? That must raise a lot of questions...

According to the error code and some googling, it apparently mean that the application was unable to start properly, whatever that mean in that context.

Don't tell me you found a sandbox escape for Bizhawk...

I will never step on tree roots again...
Games are basically math with a visual representation of this math, that's why I make the scripts, to re-see games as math. My things: YouTube, GitHub, Pastebin, Twitter

So what exactly is happening here? Mupen memory management bug?

In my (non-expert) opinion, the Windows crash seems to be caused by a vulnerability in one of the Mupen64plus N64 plugins that BizHawk uses. More evidence that plugins are bad, I guess. Fortunately most cores don't have to resort to plugins, so I think the other cores are safe. Just Mupen64plus + plugins that's the problem here.

Neat, I hope the details get posted, would be an interesting read.
