Hey everyone.

I'm new here but I have a project I want to make similar to krzysiobal post https://forums.nesdev.com/viewtopic.php?f=9&t=17696

I want to make a board to protect my NES from these 3.3v flash carts using logic level shifters that solders directly to the 72pin flash cart.

I had a few questions about these carts and wondered if anyone knew where they came from originally? (are they a knockoff of someones project or some product created by demand?)
Why do they appear to all say Mindkids on them?
Can anyone identify the 44pin chip that says SMD133 on it?

Thanks for all your help in advance.

The market for games that ran on Famiclones lasted several decades later in China than (e.g.) the US; this is basically the same hardware.

Branding.

That's the mapper IC itself. It's approximately an MMC3, plus some stuff.

It might be that SMD133 = Mindkids and SMD132=COOLBOY, but I wouldn't trust it to be that clear-cut.
