English fan translation for the SNES game
Kessen! Dokapon Oukoku IV - Densetsu no Yuusha-tachi.

The Japanese title (決戦! ドカポン王国 (ランド) IV ~伝説の勇者たち~) roughly translates to
“Decisive Battle! Dokapon Kingdoms IV: Legendary Heroes”.

This is the very first game in the Dokapon game series. The IV in the title refers to the possibility of supporting up to 4 players and was probably also mocking the numbering of JRPG that was getting out of hand. (Dragon Quest V and Final Fantasy V were already out).

QoL Improvements

	Added the ailment icons to the items that cures it. Remedy, Serum, Amulet and Salve respectively cures Poison, Paralysis, Curse and Weakness.
	Added a gear icon to differentiate weapons, shields and armors.
	Added a package icon to the item you get from a special encounter. In Japanese, the item has just the name of the delivery town.
	Changed the button icons to allow one more character in the command name. (7 instead of 6)

Known bugs

Not fixed:

• No bug reported yet.

Fixed:

• In the Rabble Tower 3F and 4F, the battle commands Escape and Counter are misspelled. (Only a visual issue) (Fix: the animated clouds in the back were overriding the text data)

Translations

Town names

The original town names are actual Japanese names mixed up. Such as ホッカ (Hokka) for 北海道 (Hokkaido), クフマシ (Kufumashi) for 福島 (Fukushima), サマイタ (Samita) for Saitama (埼玉) etc.
Since the menus only allow 4 characters for each town (6 for the churches), I couldn’t use all the original names.
So I took the creative liberty to use common Japanese words (4 characters long) for the towns:

Neko, Bara, Kaze, Sato, Nawa, Kono, Hebi, Yoko, Sora, Yama
Rika, Yuki, Kumo, Jido, Wani, Taka, Kori, Saki, Kusa, Mado
Kobe, Hana, Kino, Naku, Yoru, Koso, Miru, Kasa, Haru, Demo
Nado, Mada, Kita, Doro, Hita, Gama, Niwa, Basu, Nara, Tobu
Naga, Mugi, Dake, Kawa, Hiru, Kami, Momo, Suji, Tori, Mizu.

The churches are named:
Kokoro, Midori, Yugata, Nezumi, Suzume, Kinoko, Hotaru

Tips & Tricks

Characters & CPU

Screenshot	Comment
	Human players can pick any of 4 characters. Unlike the other Dokapon games, it’s only for the visual, it has no impact on the gameplay.
	The CPU difficulty can be chosen by selecting a different appearance. The AI can always be changed during the game although it will not change the appearance selected during the game set-up.

When holding the Select button right before the AI turn, it switches the control for this player to Human.
It can be useful to know when you accidentally (or purposefully) set all the players to CPU.

End of game

At the end of the game, 4 special prizes are awarded.

• The player who rules the most towns.
• The player who defeated the most big monsters.
• The player with the highest level.
• The player who died the most.

Each award grants a prize of 1200 + 1200 x (number of weeks elapsed) in gold.

In case of a tie, nobody gets the award.

Any Dokapon Orb kept till the end will be exchanged for 10000 x (number of weeks elapsed) gold.
As the orb sells for 490000 during the game, it seems only worth keeping if the game lasts 50 weeks or longer.

100 deaths

If you die 100 times, Princess Penny finds you so pitiful that she grants you 59630000 gold.
Furthermore the death counter rolls over from 99 to 0.

Rock-paper-scissors

One of the random encounter is a character that plays roshambo.
If you lose, they take half of your money. If you win, nothing happens unless your are in debt. In which case, your debt gets paid off.

Secret stores

There are two secret stores on the map.
The first one is near Yoru (located west of the magic circle).
It’s hidden right to the left of Yoru and accessible by going down from the road.

The second one is on the Rabble Tower island (located south of the magic circle).
It’s hidden in the west of the island and accessible by going right from the road.

Here’s the items in the stores.

The stores can be easily spotted with the Look mode.

Darkness

One of the special effects of the boss is plunging Dokapon in darkness.
When this happens, you can’t use the Look mode, use items or magic.

The visibility range is based on the Magic stat of the active player.

Magic 1	Magic 80 and higher

Magic

Offensive magic and defensive magic used in battle are tied to your equipment.
If you change weapon, you lose your current attack magic.
If you change shield, you lose your current defense magic.

Credits

There is a hidden Easter egg in the game. In the east of the map, near the town of ヒョー (Hyo in Japanese, Haru in the English version), there is a red chest.

If you look at the rock next to that chest, you will see the credit roll.

Mentioned in the credits is the music used in the commercial for the game.

The band is ACID LOVE (アシッド・ラヴ = Ashiddo Ravu).
The song is My Little Star (Release on December 1st 1993)

There is the full song : Acid Love - My Little Star

Also mentioned in the credit is the Waseda Mystery Club (わせだ ミステリー クラブ)
Waseda Mystery Club is one of the cultural circle activities that exist in Waseda University (Tokyo).

There is the TV commercial: Japanese Commercial for 決戦!ドカポン王国Ⅳ

決戦 (Kessen) means Decisive Fight / Playoff

Debug Menu

The game data contains indication of a debug mode that must have been used during the beta testing.
There’s a reference to マリオクラブ (Mario Club) which was a third party team specialized in debugging and monitoring Nintendo games. It has become an official Nintendo subsidiary in 2009 under the name Mario Club Co., Ltd.
The menu seems to allow the player to teleport to different places, trigger encounters and specific events.
Including a sound test to listen to the sound effects and BGMs.

After disassembling the rom with DiztinGUIsh, I found the code that loads the menu but not where that code is called from.
I don’t know if there is a way to trigger the debug menu from the game.

To whomever it matters, the code is located at the address 85B70A (x2B70A).

The monsters : Vampire, Lady Vampire, Sea killer, Iron Jaws, Succubus, Kraken, Scylla, Dracula are actually not used in game (they don’t have their own sprite).
They can only appear by modifying memory during the game execution (all with the Death sprite).
