This thread inspired me to run through the game again. It's definitely way harder without save states (a lot more run-backs), and I've no idea how it would be possible without exploiting the bosses weaknesses. Especially Fire Man, it seems impossible to dodge his attacks, and Electro Man can wipe out your HP with three hits???
The Yellow Devil is my favourite thing in the game. Beating it with the buster is totally doable, you just have to master the jumping and the pattern, and then it feels great when you can beat it and avoid it consistently.
