It's you against the evil Mother Brain in the thrilling battle of Metroid! You're inside the fortress planet Zebes. The planet of endless secret passageways where the Metroid are multiplying. Left alone the Metroid are harmless. But in the wrong hands they could destroy the galaxy. It's up to you to prevent the Mother Brain that controls Zebes from using the Metroid for evil purposes. But that won't be easy. You'll have to use your spacesuit to absorb valuable energy for your search to gain the use of power items like the Ice Beam, Wave Beam, High Jump Boots and Varia. If you survive, it will be you and your acquired powers against the Mother Brain.

VERSION 0.5.2 IS OUT! It now runs on Nestopia even with the RNG, and the aforementioned palette issue is hopefully gone. It also fixes a health bug on the (very short-lived) 0.5.1 version, and makes missile pickups more abundant

An update to the famous Metroid + Saving hack initially designed by snarfblam. Based off the well-hidden 0.4 version (which included wall jumping and a corner map), this version tends to improve some of the graphical issues of that version and add in new content on top of that.

New content includes:
[list]
[li]Reductions in missile door cost (5 missiles to 1 with red doors and 10 to 5 with yellow/purple doors)
[li]Manual saving via Up+A
[li]Restored Japanese RNG
[li]Sped-up door transitions
[li]Morphball glitch initially not seen in original game fixed
[li]Continuing refills all of your health, including energy tanks, instead of starting off at 30 HP every time.
[li]Missile pickups now drop more frequently and give 5 missiles instead of 2.
[/list]

You're allowed to use this hack as the base of your own hack or on other, already existing hacks (please keep in mind that the ROM of the hack must be expanded). If you would like to leave feedback on the project, please do so. This project was done with the idea of making Metroid a much more enjoyable experience, so if there's any issues with the current version you'd like to see fixed, feel free to leave feedback or critiques in the review section. Special thanks to snarfblam for making the original + Saving hack.
