Super Metroid Z-FactorDescription

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

Yay, I'm eventually done with my first hacking project. 2 years and a half working on this. Time has come to do a short presentation.



This hack is a complete make over of planet Zebes level-design wise, very few rooms actually look like they used to be. The planet is a little bigger now, it still relies on the original region structure but layed out differently. The gameplay is unchanged, no new abilities or stuff like that.

However, there're numerous small ASM changes and tweaks, mainly on PLM and enemies so as to keep the player interested in exploring. Item progression and item count has been sightly altered. Sequence breaking is also possible to some extent (might not be as permissive as SM tough)

This is NOT a hard hack but more difficult than the original game. Special/advanced techniques are NOT required to beat it. If you're not used to performing shinespark manoevers as well as the mid-air morph ball, you may have trouble getting some places later in this hack.



This project was a really interesting, but time-consuming experience, I'm globally satisfied with the result. My original motivation came from when I've played Legacy some years ago, I sensed there were grounds for building a much more interesting and extensive hack, something really close to the way SM is played but with a new aventure on Zebes.

Then as I gain more experience in the haking field, this project quickly became sort of a personal challenge, so as to prove myself capable of running a lenghty project from start to end alone. I always wanted to keep the hack simple, not really to aim at an overhaul hack that would require huge effort and time for a questionnable result.

Still, this year was very intense in the process of making this hack, I was forced somehow to rework on entire areas at some point. Several side projects like the Omega Metroid boss fight slowed down work on this hack but eventually I think it was necessary to make some pauses once in a while.

I still don't even realize it's done now, after all of this time struggling against dozen of relunctant shit... haaaa, memories. But enough talk, I'm looking forward your comments or reviews on this hack.
Happy exploring !

- When entering from above in the drained torizo room (Tourian), strange graphic glitches may appear randomly.
Some emulators seem to handle this issue quite well, some others don't. Not game-breaking.
- When entering in the first Tourian room with snes9x1.43, level data is corrupted. Game-breaking.
