Yep. I recommend Snes9x; once you have it, the file you want to load in it is https://a.cocaine.ninja/ytcdwm.smc. (Patching SNES ROMs is a pain, and I've already done it, so this'll save you the trouble.)

You need to know going in that Hyper Metroid is tuned to provide an enjoyable experience for the veteran Super Metroid player, and in absolute terms is thus very hard. In Super, you can facetank everything and spam missiles and get by just fine. Attempting the same method in Hyper will net you only frustration.

To progress, you'll need to be able to get the most out of Samus's mobility, and you'll need to know what techniques to use when, including stuff like the mockball that requires frame-accurate timing and is arguably an engine glitch. If this isn't something with which you have practice, you'll probably do well to work your way up through Project Base (https://a.cocaine.ninja/zicwwx.SMC), on which Hyper is built; they share the same mobility mechanics, but Project Base is otherwise almost entirely vanilla, and will provide a much gentler experience overall as you develop the skills you'll need to progress through Hyper Metroid without finding it overly frustrating.

Hope this helps!

I know this is an old thread, but you definitely don't need to mockball to beat HM. The springball confers the ability to run while morphed.

mockballing does allow a big sequence break though, which I guess is what you assumed was the intended route.

Oh, for God's sake, no wonder I kept getting owned so hard in Maridia! I mean, I'm probably a better Metroid player for it, but I guess I should play through it one time the way it's intended to be run, just so I have a better sense of how hard it's actually supposed to be.

Thanks for the heads-up!

Thank you very much!
