Metroid + Saving

About this project

This hack replaces Metroid's password system with a saving system, offering three save files. The file selection menu shows the player's equipment, and as an added bonus, the player's health is now saved (no need to grind for health every time you resume your game). The save system can be a handy addition for those who don't like to use save-states, or those playing on a flash-cart.

Included is a scrollable map when the game is paused and the ability to combine wave and ice beams.

Version 0.3 fixes a bug that could prevent the game from booting correctly in some cases. The hack has been tested and confirmed to work on the PowerPak as well as a normal cart.

Metroid + Saving ( + Map + Wavy-Ice) 0.3
by snarfblam


What's New In 0.3?
------ --- -- ---
Version 0.3 fixes a bug that could prevent the game from booting correctly, especially with a PowerPak. (Thanks to TheFox and bunnyboy for help fixing it.)

What Does It Do?
---- ---- -- --
Metroid + Saving adds a saving feature to Metroid, similar to that of Zelda or the FDS version of Metroid, but sexier. There is also a scrollable minimap displayed when the game is paused. Ice and wave beams are no long mutually exclusive. Aquire both and you'll have a more powerful ice beam that waves and goes through walls.


How Do I Use It?
--- -- - --- --
Use an IPS patcher such as Lunar IPS (LIPS) to apply the patch to an original, unmodified ROM. If you have a problem, verify your ROM. The PRG ROM CRC32 is 70080810. The file MD5 is B2D2D9ED68B3E5E0D29053EA525BD37C, though due to header variations, a perfectly valid ROM may not produce the same MD5.


Assembling The Source
---------- --- ------
The source code is in the "source" folder. The main file is "Metroid Plus.asm". This file is meant to be assembled with snarfblASM and applied to a ROM expanded with Editroid. Details are included in "Metroid Plus.asm". Note that the source does NOT include necessary additional graphics.
