it really doesn't take an electrical engineer to figure out what is happening
Um, that's exactly what it takes O.o. How else are you supposed to talk about technical design limitations?
but sure maybe they have some sort of new prototype flash chip that can only store saves for 10 specific games and locks once it hits 10 specific game and is unable to be changed, despite saves varying from 128kb-16mb, different save types like card1 and card2....
This is like... entirely irrelevant. No where did I mention the issue was in the saving hardware. *Very* few people know what Nintendo is doing to authenticate their cartridges. It is top trade secret stuff that takes an electrical engineer to discover/reimplement. Again, no offense, but you seem to be spouting off random ways you can think of that makes it impossible to be a technical design limitation, maybe to make it appear like you know what you are talking about, idk. But you're ignoring the thousands of ways it could be a design limitation.
but sure whatever its not DRM its a technical limit if it makes you feel better
You're stealin' my lines now hun XD. Nowhere did I say that it is guaranteed to be a design limitation, just that it is very possible that it is. You are the one that is speaking in absolutes, when ultimately all you have is unfounded layman speculation...
