Item description:

WARNING: This hack may not work with some emulators that are older and/ or for mobile phones, because of the way I implemented new ASM routines. If your game crashes when collecting a powerup, this is probably the case for you.

Well… this is a hack of Metroid Zero Mission for the Game Boy Advance.

The goal of the hack was not to completely redesign every room and map of the game, but rather to make a different, more difficult, yet somewhat similar experience to the original.
That being said, there are some areas which are very different from the original - Chozodia comes to mind as one of the areas which I have changed the most.

To create this I have used all of the following, which I would like to give credit and my honest thanks for:

The original Metroid Zero Mission(U) ROM by Nintendo

Double Helix, the Metroid Zero Mission/ Fusion editor written by Interdpth

A patch which enables the Item Toggle feature, made by Trunaur68

The (sadly incomplete) RAM and ROM maps of this game posted on Datacrystal, as well as several ARM Opcode sheets used for manual hex editing

The debug-version of VBA, as well as its normal incarnation

Notable changes that I implemented in the hack:

Kraid and Ridleys hideouts in particular follow very different paths, requiring to look very carefully at the layout to find the correct ways. Brinstar and Norfair also have a fair share of redesigned pathways and rooms, of course…

Some Item locations were swapped or otherwise moved. Chozo hint statues no longer exist. Item requirements for beating (certain parts of) the game have also changed. Unknown Items no longer are required (in fact, simply collecting them can take a while… as the Screw Attack, which is now located in Chozodia, is required to get them)

try looking for some new sequence breaks… like skipping the dreaded Power Grip. Skipping that thing may be very rewarding for the patient…

of course many minor Items were hidden elsewhere as well

all enemies have raised attack and hp, while also dropping less stuff. This also accounts for bosses, some of which also have other nasty surprises

Like the original Metroid, only one of the Ice and Wave (and later Plasma) Beams can be equipped at once. Collecting a certain other powerup may allow for equipping them all at once, though

WARNING:
This is NOT intended for the easily frustrated, or to be easily accessible. You are required to know the original game very well to sometimes make suggestions for finding the correct path. If sometimes searching for more then 5 minutes isn’t your thing, then this will likely not be your type of game…

Thanks for trying!
