Developer: HAL Laboratory
 This game has a prototype article |
 | To do: The Japanese manual has some prototype screenshots. |
Air Fortress is a simple yet entertaining shoot-'em-up by HAL. WHERE IS MY LIGHTBRASNER?

Unused Graphics
A set of border tiles that would have appeared on the map screen. These can be seen in a screenshot in the Japanese manual.
An unknown character riding a ship that bears more than a passing resemblance to the player character, found in the sprite bank for the side-scrolling shooter areas. The fact that it is facing to the right, unlike most other enemy sprites, suggests that it may not have been an enemy. This can also be seen in a screenshot in the Japanese manual.

Uncompiled ASM Code
The Japanese ROM contains several large portions of the uncompiled ASM source code, complete with comments from the programmer, as well as a couple of DOS file listings. These snippets were probably leftover data in the RAM of the computer that was used to compile the game. The American release was cleaned up significantly and recompiled, so it doesn't contain this data. This data is also absent from the prototype.

Regional Differences
Intro
The intro was completely rewritten for the US version. Note that the text was carefully formatted to fit in the same number of lines as the Japanese version.
| Japan | US |
|---|---|
ON THE PLANET 'FARMEL', THEY HAD THE GLORIEST DAYS FOR TWO CENTURIES, SINCE THE STARDATE HAD ESTABLISHED. THEY SAILED ALL AROUND THE GALAXY WITH NEW TYPE SPACESHIP CALLED 'LIGHTSHIP'. BUT ONE DAY THE PEACE WAS DISTURBED BY A MISTERIOUS BIG FORTRESS. IT WAS LIVING AND WAS DESTROYING ALL OTHER CIVILIZATIONS. THE FEDERAL BUREAU OF GALACTIC GOVERNMENT OR- GANIZED THE DEFENCE FORCE IMMEDEATELY. BUT AS THE 'AIR FORTRESS' HAD VERY HIGH POTENTIAL, THE DEFENCE FORCE WAS WIPED OUT IN VAIN. SO THE FEDERAL BUREAU HAS DECIDED TO SELECT A SPECIALLY TRAINED MAN, ID 82592, NAMED 'HAL BAILMAN', AND HAS DEVELOPPED NEW TYPE 'LIGHTBRASNER' AND 'AR- MORED SUIT'. NOW HE DEPARTS FOR THE 'AIR FORTRESS' WITH THE DESTINY OF 'FARMEL'. |
THE INHABITANTS OF
THE PLANET FARMEL HAVE
LIVED IN PEACE SINCE
THE ESTABLISHMENT OF
THE STARDATE CALENDAR.
THEY HAVE TRAVELED ALL
AROUND THE GALAXY WITH
A NEW STYLE SPACECRAFT
CALLED THE LIGHTSHIP.
THEN ONE DAY THE
PEACE WAS DISTURBED BY A
MYSTERIOUS BIG FORTRESS.
IT WAS LIVING AND
DESTROYING ALL OTHER
CIVILIZATIONS.
THE FEDERATION OF
INTERGALACTIC POWERS
ORGANIZED THE DEFENSE
FORCES IMMEDIATELY.
THE FEDERATION FORCES
WERE NO MATCH FOR THE
SUPERIOR DEFENSES OF THE
AIR FORTRESS.
THE FORTRESS TOTALLY
DESTROYED ALL OF THE
FEDERATION FORCES.
THE FEDERATION DECIDED
TO SELECT A SPECIALLY
TRAINED PERSON, ID82592,
NAMED HAL BAILMAN.
HAL'S EQUIPMENT INCLUDES
A NEWLY DEVELOPED LIGHT
BLASTER AND ARMORED
SUIT.
NOW HAL DEPARTS TO
DESTROY THE FORTRESS
AND SAVE FARMEL. |
Gameplay
| To do: There are probably more differences. |
The US version of the game was made significantly easier than the Japanese version:
- In the Japanese version, dying in a side-scrolling shooter area will return you to the beginning of that area. The US version immediately respawns you with a brief period of invulnerability instead.
- There are fewer enemies inside the fortresses. This is especially noticeable in the last few fortresses of the second loop.
- Homing bullets move in slower, wider arcs in the US version, making them easier to avoid.
- The fireballs shot by the giant robots in the eighth fortress will push you back until you hit a wall in the Japanese version, making these sections exceptionally difficult if you do not have perfect aim. These can be passed through in the US version.
Ending
The Japanese and US versions have different endings:
- In the Japanese version, when you beat the game, it shows you returning to Farmel, you get a congratulatory message, and you are given a set of passwords to play "another Air Fortress". You must then reset the game and enter these passwords in order to start the second loop. After beating the game a second time, it shows you returning to Farmel, and then you get the credits. Also, when you reach your escape ship after destroying the last core, the ship is behind a mesh with a sign that says "LY ESCAPE". This was removed for the Western versions.
- In the US version, when you beat the game, it tells you that the Air Fortress has "recovered its function," and you are then taken to the second loop. After you beat the game a second time, you get a congratulatory message and the credits. (The planet Farmel is not shown at all, as there was not enough room in the smaller US CHR ROM to include its graphics.)
For some reason, in the US version, Hideki Kanazashi's alias "Jumper Kanagushi" has been changed to "Escaper Kanagushi". However, all the other staff names and roles are exactly the same. Also, Presented by HAL Laboratory was changed to Presented by HAL America Inc. for obvious reasons.
First Ending

Passwords
The password system was changed slightly between versions:
- In the Japanese version, the three passwords GYUW + AGOG + OOON will take you to the first fortress of the second loop and activate "another Air Fortress" mode (the title logo will turn green).
- In order to enter passwords for the last seven fortresses of this loop, you must first enter the three aforementioned passwords, and then reset the game.
- The US version simplifies things by removing the "another Air Fortress" mode and giving the first fortress of the second loop a single password, ABE4. The remaining seven passwords are not locked and can be entered at any time.
- The password for the eighth fortress of the second loop is 7NDE in the Japanese version, and 7NDA in the US version.
Sound and Music
| To do: Upload sound rips. |
- The music was made quieter and cleaned up a bit in the US version.
| JP | US/EU |
|---|---|
- The music that plays during the escape scene after destroying a fortress was given a noise track in the US version.
- The music that plays during the credits is completely different in the US version, and does not loop.
- The sound that plays after entering an invalid password is completely different between versions.
Bugs
- In the Japanese version, pressing Start during the intro animation will sometimes cause the stars in the background to overlap the title logo and story text. This was corrected in the US version.
- A couple of exit tubes in the eighth fortress of the second loop are bugged in the Japanese version, and will either place you inside a wall (with jumbled graphics) or set the wrong scrolling mode, forcing you to reset the game. These were thankfully fixed in the US version.
- In the Japanese version, the noise channel will occasionally get stuck playing noise during the escape scene that plays after destroying a fortress.
Miscellaneous
- In the escape scene that plays after destroying a fortress, Hal remains stationary in the middle of the screen in the Japanese version, and moves slowly from the left side of the screen to the right in the US version.
- The CHR ROM was shrunk from 128 KB to a mere 32 KB for the US version. This was accomplished by removing the graphics for the planet Farmel (as seen in the aforementioned Japanese ending), changing all eight Air Fortresses to use the same two CHR banks, and making better use of free space in several banks.
