How is it possible that classic 3D video games such as Super Mario 64 and Ocarina of Time can contain such bizarre "glitches"?
3D games like Super Mario 64 and Ocarina of Time are time-step-based physics simulators. Their basic design is based on the assumption that nothing goes above a certain speed. Each frame, Super Mario ...

How can tilting a N64 cartridge cause such subtle glitches?
The main point to understand is that the console is limited. RAM on the console itself is faster than memory on the cartridge (and the cartridge memory was usually read only, with a little non ...

Why did Nintendo 64 (1996) memory cards require a battery inside them to retain data whereas the PlayStation (1994) ones did not?
Most likely different acrchitecture comes from idea how memory cards will/should be used and what are the available interfaces to access them.
The PS memory cards do have flash memory, but the bus to ...

Why is a BIOS dump not required to emulate Nintendo 64 games in most modern emulators?

Can a Japanese (or US) PSU for Nintendo 64 be run with 230 V mains?
The supply shown in the video will most likely blow up if you connect it to 230V mains. At 1:08 in the video you see the printing "200V" on the main filter cap. There is no plausible way to ...

How is it possible that classic 3D video games such as Super Mario 64 and Ocarina of Time can contain such bizarre "glitches"?
The short answer is: These games are built on code which is supposed to simulate the laws of physics, at least for motion. But they are also games, which means that that code has to run fast enough ...

Can removing a cartridge from an NES (or any other cartridge-based game system) damage the hardware or software?
The NES can be damaged by software, so removing the cartridge at just the wrong timing could theoretically damage the console.
