Can someone give me a quick rundown of the whole 60-pin/72-pin/3-screw/5-screw

Famicom uses 60 contact pins.
NES uses 72 contact pins.

Many of the first wave of NES titles have cartridges that uses 5 screws on the back, where as the 3-screw design became the standard quickly thereafter. Because early in the NES' life there was a slight shortage of NES boards, they used famicom boards instead and placed an adaptor right inside the cartridge.

I believe there's 18 titles that potentially used the 5-screw cartridges, and all of them have a chance - albeit a small one - to have an adaptor inside. Gyromite has the best chance of having one inside, but once again its not a guarantee. You can sometimes tell if a game has an adaptor inside by the slightly heavier weight to it.

Famicom carts have 60 pounds, NES ones have 72. I could explain why. When the NES was first introduced, the launch games all had a distinctly similar black label. The earliest released ones are held together with 5 screws while later versions only have 3 like 99% of NES games. Of these 5 screw black label NES games, some examples of some titles are actually literally the Famicom game's pcb with an adapter made by Nintendo. These are generally considered the best Famicom to nes adapters. There are no Nintendo made adapters that do the opposite although there are tons of generic ones as they don't need to have a key chip (only front loading NESs have lock chips).

Maybe I'll post some pictures of both my adapters later if you want. Gotta take my kid to some animal show or something atm.

Freudian slip.

He was thinking about how much weight he needs to lose.

I've also heard that you can spot a cart with an adapter by looking at the pins. If they are T shaped, it's a regular cart. If it's L shaped, there's a converter in it.
