You don't know enough to sat that. Every single component on every pcb is specific in both placement and function. The capacitors are holding charge to keep specific nearby components functioning properly. The resistors are regulating the flow of electricity to keep the current within acceptable range. Edge connectors exist to allow connection to other components, and so on. A console pcb and a capture card perform far too different functions to share that many components and placement. It's not jumping to a conclusion in this case. It's a factual observation that the pcb in that shell is in no way a console pcb.
The burden of proof on a project like this is on the development team trying to use these fakes to build funding and business partnerships, and it would be the simplest thing in the world for them to take five minutes and shoot photos of the functioning prototype from multiple angles and upload them. It would take literally less than five minutes to shut the whole world up. They don't because they can't. They can't deny that the new prototype contains a capture card. They can't deny that the toy fair unit was a Super Nintendo, because that's what they are. It's not up for debate, so they don't debate it. They delete, skirt the issue, and say, "just wait, it's going to be awesome."
What would have been awesome would have been not using fraudulent materials to try and build a business. People would have waited. People wanted to believe, and to support this project. The backlash is so vehement because of the flippant disregard for the intelligence of the potential backers to insultingly think that none of us were going to recognize the problems with the hardware. Retro gaming enthusiasts repair broken hardware. We rebuild arcade pcbs and cabinets. We flash roms to replace corrupted ones, we remove lockout chips, and we build gaming PCs. This tech isn't a mystery. It's stuff people recognize because they are familiar with it. Your lack of familiarity does not make them wrong. You're choosing to ignore it because you don't understand it or just so badly want it to all be real that you're ostensibly closing your eyes, putting your hands over your ears, and singing the national anthem.
