Debug Mode

WELCOME TO CONFIG.SYS

The Game Genie code PENNOYAA re-enables debugging options that were cut out of the final game:

  • Any level can be selected without the level select trick.
  • Death/Non Death toggles invulnerability.
  • Weapon Select (Choose between 1-5).

Additionally, hold Up + Start on the "Nexoft" screen before it fades out to view the ending.

to MASTER UP,
This might end
up being my last
Famicom game.
It's not much
for 4 months
work, but I
think that it's
playable, at
least. Where
will our paths
cross next,
I wonder?

Regional Differences

Title Screen

Due to having more copyright info, the mode select has to use another screen.

Opening

Hmmm...
To do:
Get the rest of the story text.

The Famicom version has a longer opening and ending. The visuals for the Japanese opening and ending can actually be seen in the NES version by doing the "Death & Non-Death" cheat, but the text that accompanied them was removed.

Japanese Translate
Gun Nac JP Opening (1).png This is a tranquil galactic system,

composed of seven planets and an artificial sun...
But now, that peace has come under threat.

Gun Nac JP Opening (2).png Strange creatures began to mix in with what

the factories around the worlds were creating.
Eventually, they started to attack the people.

Gun Nac JP Opening (3).png No matter how many investigations were performed,

the cause of this incident remained unknown.
The creatures produced grew more and more evil,
and eventually took over the factories,
plunging the worlds into chaos.
Though a defense unit was established,
they were completely outmatched by their mass-produced foes.

Gun nac-1.png During the fifteenth meeting,

just as everyone was falling into despair,
the world's greatest mage suddenly appeared before them.
"It is no ordinary foe who wreaks this havoc.
It is an evil entity who delights in conflict,
using power beyond our means to control the worlds.
We cannot win with conventional warfare."
"But do you know of any way to defeat it?"
"We must seek help from a world different from ours...
another realm with powerful fighting capabilities."

Gun nac-2.png A summoning was performed,

the world's last desperate hope.
A way was opened between the earth,
which the mage had filled with
fighting power, and the heavens.
And then...!

Gun Nac JP Opening (7).png Energy surged into the room alongside

a great light, and poured into the mage's body.

Gun nac-3.png ...And so, the mage boarded the ship that

had appeared at the same time as its pilot,
and flew off to a battle for the fate of the world.

Stage Names

Japanese Translate
AREA 0 星の星 Planet of Stars
AREA 1 月の星 Planet of the Moon
AREA 2 火の星 Planet of Fire
AREA 3 水の星 Planet of Water
AREA 4 木の星 Planet of Wood
AREA 5 金の星 Planet of Metal (Money)
AREA 6 土の星 Planet of Earth
AREA 7 日の星 Planet of the Sun
AREA 8 日の星 内部 Planet of the Sun - Interior

AREA 0 is a hidden stage, accessible by selecting track 5 on the Sound Test and then choosing which Area to begin the game.

Each stage is based after an element and are listed in order of the days of the week, starting with Monday (Area 1) and ending on Sunday (Areas 7 & 8). Area 5 is also a double meaning where "金" also means "money" matching the level theme.

Enemies

Enemies in Area 2 are greatly different in both versions. In Japan version there are cigarettes and matchboxes that fire matches, while in US version they are replaced with petrol containers shooting missiles. The "fire pillar" ground enemies in later halves are also changed, from lighters in Japan version to refinery stations in US version.

Gun Nac (Japan) RD sprites-2.png Gun Nac (USA) RD sprites-2.png
Gun Nac (Japan) RD sprites-3.png Gun Nac (USA) RD sprites-3.png

The most notable change is the mid boss, which is a "value pack" of matchbox in Japanese version, but a more robotic object in the US version. The same enemy also appears in middle of Area 8.

The first form of final boss in area 8 is also different. In Japan version it somehow resembles a baby, but the US version is more grotesque.

Ending

Hmmm...
To do:
There are still texts not listed.
Gun nac-4.png

Once the mage returned to the planet, the power vested within her vanished alongside the fighter jet. Everything returned to normal.

Gun nac-5.png

While everyone praised her achievements, the mage could not forget.

Gun nac-6.png

Huh...?

A trophy? There must be some mistake...

This isn't a sport...

Staff Roll

The Japanese and US staff rolls are different from each other. Interestingly enough, the US version still uses Japanese text.

  • The Tonkin House section of credits in the Japanese version was changed to Tokyo Shoseki in the US version, but retains all the same staff members.
  • After the staff roll in the Japanese version, we are presented with COMPILE and TONKIN HOUSE, each with their respective logos. In the US version, we are presented with COMPILE AND TOKYO SHOSEKI with PRESENTED BY NAXAT CORP. underneath it, all with their respective logos.
  • Apparently, the dev team didn't feel Toshiaki Sakoda was really a Pro Golfer, as they removed the "Pro" in "Pro Golfer" in the US release.

Evaluate Screen

According to the game difficulties, a few screens will appear along or after the staff roll. Interestingly, the "You haven't won yet" screen shows a granny who looks like the boss of Area 5, implying that she is the master evil of the mess.
