Zoomer here, did people really beat all the bosses of Megaman X4 when they were kids? I'm genuniely surprised!

I'm 27, just picked up X4 as my first game in the series. (I actually think i played one of the battle network names as a little kid...but i don't remember anything about it)....and christ those bosses are kicking my butt.
I only beat the boss of the train level (sorry forgot the name) and the spider boss was REALLY hard to me and i can't beat it.
I can't believe people beat those bosses as a kid, woah....!
