The game is Metroid Zero Mission, this is the first time I beat a Metroid game, so I decided to start with this one.
I should mention that I used save states and rewind to get the hardest items, but hey, I don't have the time to master all the games I play ¯_(ツ)_/¯
Learn from my childhood with trying to 100% Metroid Fusion.
There's an item in a section of the world that explodes on a timer, and you can't return to collect it later so you end up stuck with a 99% complete file. ☹️
What the hell?
No save point before the end!?
Thankfully we have save states nowadays 😃
I didn't know I had missed it until I had already saved past that point
