About those Starfox Adventures "impossible challenges": I thought the escort mission was challenging, but not too challenging. I've also discussed the matter of the Test of Strength before... How is it that everybody hates the Test of Strength and few found the Test of Fear challenging, again?
The Test of Fear was challenging, but I learned to stop paying attention to the screen and focused solely on the bar at the top. Plus, I made very small movements on the control stick, which seemed to help. Still, near the end the meter thing shoved all the way to the left and was a hair's length away from going off the edge. I felt like I was pushing against some heavy weight to push the meter back to the middle, considering the meter was shaking like mad at that time.
Thanks to YouTube, I can now see what I missed this whole time. And I say that every single time the Test of Fear comes up, because I keep thinking the Test of Fear was memorable for the visuals that went on (something about seeing the fear in Fox's face... or, no, wait, I bet that was with the T-Rex fight).
I hated the Test of Strength because I'm not a fast button tapper. It takes me a few tries to get into the zone where my finger twitches rapidly enough (and I nearly kill my finger in the process) in order to do it. Had to do that focusing to unlock the secret battle stages in Bomberman 64 without getting all the gold cards. Had to unfortunately repeat that trick here. Someone suggested some tape and something else to rapidly tap the button for you, a way of cheating, but at face value that technique looked ridiculous. Never tried it.
