It isn’t. At least not unless it’s boxed with manual and in mind condition. But then that’s not really a fair comparison because if the GBA was boxed then that would be worth more too. Gameboy games are the one area of retro consoles that hasn’t ballooned in price during the last few years plus Pokemon Yellow is a pretty common game too. That said, GBAs aren’t exactly commanding a high price tag either. So there isn’t actually that much between the two price wise.
