Ah lemme guess, it's about PCem/86Box. Alright, I'll bite. Let's see how shit it will be.
EDIT: Okay, so obviously they are skimming over lots of details.
For example, PCem isn't super easy to configure, as you're configuring a VM like you would a real computer back in the day, and you can run into certain hardware related problems. Plus, the process of installing Windows 98 is a pain in the ass, and you will need to have all the drivers required on hand, and find a way to even put them on the VM. They've only barely mentioned that it's not as easy at the very end of the video, but completely omitted the fact that you need to install drivers manually because this is not Windows 10 with connection to Microsoft's servers that will instantly find and install every needed driver for you.
And Linus, being Linus, completely skimmed over a certain fact. He just said "E we just have the 13900k and it emulated Pentium II". The said Pentium II is a 350MHz one, and what's worth noting is that it's insanely demanding to emulate that processor at that speed, where the 13900k might as well be a must to run that. I tried emulating that on my 12400 at lower speeds and the emulation wasn't keeping up. Again, an average viewer might think they can plop the exact same config on their machine and it will run just as well, only to realize just how demanding emulating the Pentium II is. 86Box devs even made a whole blog post explaining why the Pentium II is as far as they're willing to go because of how hard it is to emulate the Pentium II already.
Speaking of, they only barely mentioned 86Box and DOSBox-X, even though they are superior forks, as they are way more actively developed than PCem and DOSBox. They've mentioned that they had to use a Folder2ISO program to get files on the VM. Well guess what, 86Box actually made it better and you can just pick a folder on your physical machine and it will get mounted as an .iso on the VM. And as for DOSBox-X, well, compared to DOSBox it is way way more versatile, as DOSBox's actual development is insanely slow. 0.74 was released in 2010, and the current 0.74-3 from 2019 is just a tiny little bugfix, because DOSBox devs really don't want to overdo the feature set in their project since it's actually used by companies like GOG. Meanwhile DOSBox-X can even emulate Windows 98 and Voodoo graphics, albeit not to the same extent of accuracy as PCem/86Box, but it's an option.
Since Tech Shrek was clearly the mastermind behind the entire video, while Linus was there to just be the talking head, I feel like Linus really needs to give him a separate channel where he goes in-depth in all the weird shit he does for the main channel, as these are very interesting topics and Anthony knows his shit, so he should really give him a channel so that he can make lower budget, but more in-depth follow-up videos for people that are really interested in what was talked about in the main channel video. That is, if Linus actually cared about letting Anthony educating the masses on emulation autism and not using him to bring a very interesting topic and dilute it so badly that you don't even get interested in it as an average viewer.
