Ok ,I'll try this one more time:
Game cartridges are not made individually. They are made en masse. Like, hundreds of thousands all at the same time.
For example, the initial pressing of Japanese D/P had a few pretty big glitches such as Ditto being able to keep moves that it copies during Transform, and the E4 Surf Glitch allowing you to capture Darkrai and Shaymin. These only existed in the initial pressing because, presumably, officials caught wind of the glitches and fixed them so that later pressings don't have them.
A more recent example is a defect in some baby strollers that caused severed fingers in a dozen or so cases (source). One million were recalled likely because they were made around the same time with the same materials, and if there's a problem with some, there's a problem with all.
It's nearly impossible that just YOUR 3rd gen Pokemon game is defective due to it's manufacturing. You're more likely to win the lottery tomorrow. It's far more likely that you or someone else took poor care of it. Because somehow, millions of others were pressed, likely from the same plant yours came from, using the same materials and the same workers working the machines, and they made it out fine.
I have several dozen Gameboy fat and GBA games that work fine, some of which have been put through nothing short of hot cars out in humid weather with no shade.
I guess? I'm not arguing about cloning. But your claim that your game is/was defective due to it's manufacturing is, at best, unprovable. At worse, a lie.
