Mega Man X (SNES): the all-items password and how to get the Hadouken

The Mega Man X password system was a notebook all by itself. Twelve digits, in a grid, copied down in fear of swapping a 6 for an 8 — because getting one digit wrong did not give you “invalid password”. It gave you a strange half-state, with some weapons and no heart tanks.

Here is the code that unlocks everything, plus an explanation almost no list bothers with: why the Hadouken never shows up in a password.

How to enter the password

On the title screen, choose Pass Word. The password is a grid of 3 rows by 4 columns — 12 digits total.

• Use the D-pad to move between cells
• B cycles the number up
• Y cycles it down
• Enter it left to right, starting from the top-left corner
• Start confirms

The all-items password

8441
2136
4421

This gives you: all 8 Mavericks defeated, all 8 Heart Tanks, the 4 Sub-Tanks and the 4 armour parts (helmet, boots, body armour and the upgraded X-Buster). You land straight on the road to Sigma with a fully built X.

Type it exactly like that, row by row: 8 4 4 1 on the first, 2 1 3 6 on the second, 4 4 2 1 on the third.

Why so many different “everything” passwords exist

You will find codes completely different from the one above also labelled “everything”, and all of them can be correct. The reason is structural.

The Mega Man X password does not save your progress — it saves only 24 yes-or-no variables:

• 8 bits — whether each Maverick is defeated
• 8 bits — whether each Heart Tank was collected
• 4 bits — whether each Sub-Tank was collected
• 4 bits — whether each armour part was collected

Because the game encodes those 24 bits into 12 digits with room to spare, more than one numeric combination represents the same state. There is no single “correct” password: there are several equivalents.

That also explains what the password does not hold: lives, filled E-Tanks, position in a stage, score — and the Hadouken.

The Hadouken: why no password saves it

Look at the list of 24 bits above. There is no bit for the Hadouken. It simply does not exist in the password format.

The practical consequence, and the part that defeats most attempts: you have to get the Hadouken and finish the game in the same session. Turned the console off, or used a password after picking it up? Gone.

Requirements

For the capsule to appear you need absolutely everything:

• All 8 Mavericks defeated
• All 8 Heart Tanks
• All 4 Sub-Tanks (filled)
• All 4 armour parts
• Full health and weapon energy when you reach the spot

The password above covers the first four in one go — which is exactly what makes it useful for this hunt.

Step by step

1. With everything collected, enter Armored Armadillo’s stage.
2. Finish it and repeat — you need to play it four times, reaching the end with health and weapons full.
3. On the fifth run, ride out to the mine cart section. Take the third cart across the canyon.
4. Before the boss door, climb the wall to the left instead of going in.
5. At the top sits the capsule — with Dr. Light dressed as Ryu.

How to use it

The command is the Street Fighter one, and this is where most people go wrong: ↓ ↘ → + fire button. The diagonal in the middle is mandatory — “down, forward, fire” without passing through it will not come out.

You can only fire it at full health. In exchange, the Hadouken kills practically everything in the game in one hit, Sigma included.

Why this game still matters

Mega Man X arrived in 1993 and reinvented a franchise that already had six NES entries. The dash, the wall climb, the armour in parts — everything that became standard afterwards was already there, and the opening stage teaches each of those mechanics without a single text box.

For the full story of that leap, we wrote about the 16-bit revolution Mega Man X represented.

Sources checked: the all-items password was cross-verified between the World of Nintendo archive and ChapterCheats, which list it with the same description. The 24-bit structure of the password system comes from StrategyWiki’s documentation, and it is what confirms the Hadouken cannot be stored.

Got a different password that works on your ROM? Leave a comment — given the 24-bit structure it is probably a valid equivalent and worth adding to the list.
