Theoretically there wouldn't be a limit as you could just keep swapping out better SCD's.
Assuming the system has a way to completely offload the processing to the SCD that isn't bandwidth constrained that is.
There's no limit in theory as long as you have the bandwidth to send the video and audio one way and the network/media information the other way, as the ultimate configuration would be something like a segacd/32x type system. I'm kind of confused why people are so excited for that kind of idea though.
Thank you for the responses!
I keep seeing that there would be no limit, and I guess it just seems (as mentioned) like a Sega 32x sort of thing where it'd upgrade but still have some sort of constraint. But, hardware processes have probably come a long way since then, and as mentioned, as long as the bandwidth is controlled it's no problem. Plus, it may just be a matter of what things get routed where.
But, I guess you'd have to hit a point sometime where it makes more sense to upgrade the hardware itself? That's probably up to Nintendo though for when that'd be. Ridiculous thought, but I'm imagining taking a SNES and SCD-ing the innards from a PS4 to it so that the SNES is the main system and processing through the PS4. Really, Really Super Mario World.
Oh, another thought though...
Remember how you could stick in a flash drive into a Windows computer and use the spare space as "extra RAM" while it was there? I don't believe they allow this anymore. But, in the case of external hard drives, is this a process that actually works? I'm sure it has limits too. I guess they would just put extra RAM into the SCD, but if they could put a hard drive instead for storage and RAM boosting, I'm wondering if they'd go for that instead.
Yes, I am hardware ignorant.
There are two limiting factors to this setup (as far as I can tell):
1. Connection speed: if we theoretically keep adding SCD after SCD in a daisy chain manner described in the patent, eventually the connection speed will drop and some processing issues will crop up. Now, an alternative to this is to only allow 1-3 of any type of SCD to connect, and then come out with SCD2.0, or a twice as powerful SCD to take the place of two previous SCDs.
2. Fragmentation of the user base: if Nintendo allows users to use as many SCDs as they want, so that maybe an enthusiast graphics lover connects 10 SCDs to their console to match a high end PC (hypothetical/theoretical of course), Nintendo would need to allow their games to scale appropriately depending on the amount of SCDs attached.
Frankly, I think #2 is a bigger issue because, while scaling between 2-3 different power levels is rather easy these days thanks to middleware like UE4, supporting any number of configurations (a la PC) is not something console game devs would ever want to do, especially Nintendo's teams. Which is kinda why they stick to their own consoles.
I see the SCD being used as a 1 time upgrade per SCD model, so that you can have the base NX, and then the Super NX by buying and attaching the Super SCD (or a better name). Also this could make the NX future proof and allow it to be upgraded indefinitely, so that everyone who wants to play a Nintendo game for the next, say, 10-15 years MUST buy at least the NX base console. If marketed properly, that would be a terrific incentive to get people to buy in early, and build a large userbase from the beginning.
Edit: And yes, I would love if we could have a general NX speculation thread, because that discussion in the last one about the pros and cons of cartridges was really fascinating, and I'd love somewhere to discuss the inevitable "gimmick" but I suggest we stick to talking about the SCD patent in this thread.
Yeah, game scaling is an issue for sure as there'd be a limit at some point for any one game at any one point in time. I see the SCD thing as pretty cool, but maybe once or twice a generation at most, just to try and get closer to the higher levels or performance out there (probably on a PC at any point).
Skittzo0413, I think you mentioned in the last thread about a modular console. They have modular cell phones now, so why not? Yeah, this thread should stay focused on SCDs, but I'm debating between starting a new thread discussing the feasibility of console cartridge gaming currently or collecting a few patents and things to discuss Nintendo possibly creating a modular console, and their interests and pursuits thereof (such as the oft made fun of fact that Wii U can apparently use anything back to a GBC to play games now). Since you're a junior still, we can PM and discuss those thoughts and can get such a thread going if you're interested? That way I don't contribute to leading this thread astray anymore, haha!
