Hey! I'm the author (many many (many) years ago) of Metroid X. I was doing one of my occasional narcissistic searches for people talking about the hack, and your map came up.
I'm beyond flattered; you put quite a bit of work into it, and it's gorgeous! Heck, there's a lot I don't remember about the edit so it's a useful reference even for me. I'm totally saving a copy (if that's okay).
I really appreciate when anyone spreads the word about Metroid X, and this is doing so in the best possible way! Thank you!
I'm glad you liked the map! Of course you can keep a copy of it. I'm kinda bad at attaching a proper license to any of my creative stuff, but you can do anything with it as long as the attribution remains in place. (The map in question, for you folks at home.)
As a bonus, you can also have a couple other charts and graphs I cooked up for a Let's Play I did a few years back, (before I made the snazzy map in question). (Extra bonus chart of the dependency graph above, but with a minor items only variant.) I thought progression structure --- with the major items following a set sequence but the minibosses being available as soon as the player is ready --- was a really clever twist on the Metroid formula.
Anyhow, back in 2020 I made the foolhardy decision to try playing through every Metroid 1 hack out there. I made it about 75% of the way there before petering out (my percentage has remained roughly the same since then, even with the new releases). Thanks to that experience, I can confidently say that of all the hacks released during the MetEdit era (circa 1999-2010), barely anything else comes close in terms of awareness of limitations, design sense, or aesthetic sense. It was a very auspicious start for the Metroid hacking scene!
Recently, I've run into some hackers who've expressed interest in remaking your mod in another game (Metroid Zero Mission, IIRC), out of respect for the OG Metroid mod. I don't think they've started actually making it yet, but if they got your (un)official blessing that'd be really cool.
Thanks for the kind words!
