Remember: hold RESET while you turn POWER off, or your game may not be saved !!
>>730642680>"ahhhhhhhhhhhh why did I not hold RESET while turning the power off, my game is not saved whyyyyyyyyyyyyyyyyyy?!?!?!">*man burning in hell.jpg*
Literally no one did that
>>730645065I did that all the time.
>>730645240Nerd
>>730642680i have never done thatwhy would you even need to do that
I have to shit so fucking bad right now
>>730645440When holding Reset the CPU pauses all execution of commands. During shutdown the entire system doesn't turn off instantaneously. The CPU can sometimes incorrectly read a capacitor discharging as as errant "write to save data" command and try to overwrite your save with whatever garbage bytes it's still reading in the RAM as it's powering down. By holding reset you prevent this.
>>730645614why didn't it do that with just one button
>>730645653Just never thought of it.Nintendo thought the Famicom was just going to be getting arcade ports and simple games. They never considered games would get more complex and require saving.This was eventually solved in later cartridges, requiring ROM switching in order access the SRAM that a CPU instruction couldn't error to.
>>730645653Because then you'd have to build a circuit into the board that does explicitly that or build it directly into the CPU all for a feature no games even supported the first couple years of the console's life. Remember, in 1983, everything you added to a CPU was something that could fail and reduce yield amounts. CPUs back then didn't even have multiplication or division built into them and just used iterative addition and subtraction. The transistors needed for the "don't execute during power down circuit" are just one more point of failure, not to mention the challenge of determining "am I being shut down or are these commands legitimate?" It was easier to just tell players to hold reset.

games didn't save back then, you needed to write down the password
>>730645790It’s pretty wild how ahead of its time the Famicom was. Compare it to the SG-1000 that released the same day and they might aswell be different generation systems. The external coprocessor support helped in longevity for sure.

>>730645614look at this big fat faggot full of dogshit up to his eyeballs>"write to save data" commandare you fucking retarded? learn assembly before talking out your ass.
