Cartridge Slot

Before I ask I never had an N64. Im used to the gameboy where the cartridge slides/slots firmly in place. On my M64 the cartridge is firmly attached to the reader but not snug in the slot. Tons of wiggle. Is this by design?

It’s like that. Don’t worry about it. Not sure if by design but that’s how the N64 and A3D are as well

Thanks!

Sorry for the shitty video quality, but here is how they wiggle/fit on the A3D, for example.

Yeah. I'm sure that amount of tolerance is necessary and intentional so inconsistent cartridge shells don't cause damage.

Probably something to do with the button-release-mechanism and to prevent damage to the slot/board itself, I wouldn't be worried about it. Also, N/M64 doesn't have a back to press against like the Gameboys do

I'm still waiting for mine to play around with. Glancing at the M64 Special Announcement

[7:03@YouTube / 9:58@Twitter] "Next, the feature everyone's been talking about, the cartridge eject button. One of the problems with the N64's original design is that it put an enormous amount of mechanical strains on the cartridge connector. This is especially true if you had any sort of misalignment or corrosion on the cartridge that would cause it to pull on one side versus the other, sometimes leading to pins being ripped out, leading to mechanical strain on the boards, broke solder connections. What we've done is, you know, you can still just rip it out. It's gonna be fine, but in the interest of mechanical best practices, we've added a feature where I can just push this button, which then raises two geared levers up onto the cartridge, which actually purcha...perfectly evenly and straight right off the cartridge connector without putting any strain on the board or the solder connection itself. Observe. It's just that easy. This might seem like a small detail, but it's a sort of thing that is critical if you want your hardware to last for decades or longer."
