I Have Two Identical MK1 SNES Carts & One is Heavier?

[darthmunky]

I've had Mortal Kombat 1 on SNES for many many years now and my brother recently bought a copy for his own collection and just for the heck of it, I decided to compare his to mine, They are the exact same except for one thing, Mine is heavier. I gave them both to 5 different people without telling them which one was which and all of them said that mine felt heavier so now I know it's not just me. My question is: How & why?

I couldn't guess, but that's interesting. And kind of odd.

Pop'em open and find out.

Your cartridge probably has Ermac?

Perhaps one was manufactured later than the other, and they changed how they built the cart a bit?

Definitely possible as that's a game that probably had a few reprints.
