Seems like splitting hairs. The redstone mechanics needed to run the computer are implemented exactly the same as the real game. The computer can be loaded into real minecraft and runs as expected. MCHPRS just takes out what the computer doesn't use and optimizes the simulation of it. I would call that a computer running in minecraft, but you could argue either way.

Almost like running a game in a NES emulator at 10,000x speed and claiming it's implemented exactly like the NES.

  If the NES game in question ran at 18 hours per frame on real hardware, then I think people would give it a pass. This project is beyond awesome, we can spare it the usual HN nitpicks.

    The project is awesome. These comments (include mine) need correction.

  Not quite. Almost all NES emulators just emulate the inputs and outputs of the chips involved, they don't actually model the chip layout exactly. That's a limitation of emulating hardware in software for the most part. Without perfectly implementing the chips involved with all their associated timing and clocks there's no guarantee that some behavior might be slightly different. When emulating software in software, it's much easier to confirm that the exact same operations are done, and you can in some cases fully verify the solution.

  Yeah I would say that your example is implemented exactly like the NES.

this may be a stupid question: is it CPU or GPU dependent, Can it be "sharded" and run on multiple machines in cloud?

  There are no stupid questions ;) To my understanding, this is almost a pure CPU task, like how normal minecraft currently works. Which would actually make sharding a little easier if they implemented it (sounds like they haven't). The GPU is an interesting point though. There's probably a ton of simple matrix multiplying in the machine's design that could benefit from a GPU.

    There are no stupid questions? I’ve seen a grown man ask a pregnant teenager whether she was the mother.

    Imagine a “meta” compute environment that only runs embedded with Minecraft built circuits like this - someone needs to craft a crypto-mining circuit within Minecraft :-)
