3rd Party Expansion Pak for N64

[burningdoom]

Does anyone know anything on these? I'm trying to search the web for info and all I can seem to find on mine are short 2 sentence reviews, or obviously made by the company reviews that way overpraise it.

The thing is, I bought my N64 with the Expansion Pak already in it. I never took out. It was red. So I always thought it was the official Nintendo Expansion Pak. But I was watching MetalJesus's newest video on YouTube today (N64 hidden gems), and I noticed his Expansion Pak had circular holes on the top, while mine had slotted vents. So I took it out, and lo and behold, I have a third-party Nyko Expansion Pak called the "Booster Pak".

Does it work as well as the Nintendo one? Does it have the same amount of memory? Is there any compatibility issues with games? Do I need to get a Nintendo one instead?

Thanks for any help you can give me on this thing.

Here's a couple pics of it (sorry about my shoddy camera work):

Does Donkey Kong 64 or Majora's Mask come on?  If so, it works.

I use a third party N64 Expansion Pak in mine, and I've had no issues with what I have played it with (the only game that I've tried that actually needs it is Donkey Kong 64). I doubt you'll have any issues with yours.

I also have a 3rd party expansion pack and it works fine. That being said if I ever come across a 1st party one I replace it no questions asked.
