Pokémon Card GB2/Debugging Material

This is a sub-page of Pokémon Card GB2.

Start-Up Debug Menu

The Start-Up Debug Menu

Enabled with Game Genie code BE0-37B-08C, this menu will pop up when the game first boots.

Power On (パワーオン)

This will boot the game as usual.

Coins (コイン)

Shows all the game's event coins (not just the ones you own) to choose for the "Duel" option. If no save is present, the game will default to the Chansey Coin.

Config (せってい)

Adjust configuration, same as the regular in-game menu.

Effect Viewer (エフェクトの再生)

The same option as the one from the main debug menu.

Staff Roll (スタッフロール)

Plays the credits.

Duel (たいせん)

Starts a duel against a random opponent from the Lightning, Grass, Psychic, and Science Clubs, as well as Aaron and Sam. This option will pull the player's deck from the current save file. If none is present, the game will try to generate a deck, though this process seems fairly broken. It appears the player will end up drawing seven identical cards on the first turn, though there is no check to guarantee that this will be a base Pokémon, thus potentially causing a softlock if one ends up with a hand consisting of nothing but trainer cards or energy cards. Only Aaron and Sam are safe to battle, since the player will draw the tutorial deck every time.

Other oddities caused by the lack of save file include:

• The coin toss screen will lack a default player name, and the border of the text window will be partially miscolored.
• The player will default to be Mark, though one of the possible opponents is… also Mark (or rather, "Main Character").
• When fighting against "Mark", the game will glitch out during the initial card drawing animation, before ending in a loss for the player. Oddly enough this happens even when a save is present.
• The drawn Pokémon may start their first turn with no HP left.
• The drawn Pokémon may change on a whim based on what the opponent draws next, which includes things like energy cards.

Slot Machine (スロットマシン)

Used to test the 5-coin slot machine, giving you 100 coins in the process (though these don’t carry over to your save file).

Exit (とじる)

Will exit the menu and start the game normally if the cheat code is off. Otherwise it will only reload the menu (same as when B is pressed).

In-Game Debug Menu

The In-Game Debug Menu

Enabled with Game Genie codes 418-50B-91B + 508-4FB-800 + 048-4EB-F76, this menu will replace "Coins" in the regular in-game menu. Some options here are repeats from the start-up menu, with even the name being the same, with it being "Shortcut Debug" (近ドウデバッグ).

BG Font State (BGフォントの状態)

Split into two "pages", with the first showing the font, and the second the current background tiles. Press A or B to advance forward.

BG Face Display (BGフェイスの表示)

Shows every duelist's faces next to yours. There are 96 portraits, each with their own expression "states", with 0 being neutral, 1 being happy/winning, and 2 being sad/losing. When selected, this option starts at the fifth entry, which is Ronald's portrait. Entries 1 through 4 are assigned to Mark, Mint, and then their link battle counterparts. All of them lack expressions: you can scroll through them, but they all reuse the default portrait.

Controls:

• Left/Right: Scrolls forward/backward through the expressions.
• Up/Down: Scrolls forward/backward.
• A/B: Exits the menu.

Effect Viewer (エフェクトの再生)

You can test out all of the game's move animations. There are 256 options (0-255), but there are only 140 animations (1-141), including things like screen shakes.

Visual	Japanese	Translation
	A<###>　　　　<STATE> <SIDE>　　　START:入替	A<###>　　　　<STATE> <SIDE>　　　START:SWAP
	A:実行 <00> <00>　　　 B:中止	A: PLAY <00> <00>　　　 B: STOP

"State" refers to either "Playing" (実行中) or "Stop" (テイ止), while "Side" refers to either "To left, from right" (左から右へ) or "To right, from left" (右から左へ). The two values in the bottom left corner are updated as the menu gets used: both change to 01 01 when an animation is played, with the second value briefly changed to 00, and then back to 01 when the same animation is played again. Pressing B will reset everything to 00 00.

Controls:

• A: Play the selected animation.
• B: Stop the currently playing animation.
• Left/Right: Scrolls forward/backward.
• Up/Down: Scrolls forward/backward by an increment of 10.
• Start: Change on which side the animation will play (player or opponent).
• Select: Exits the menu.

OBJ Character Display (OBJ人物の表示)

Shows you all the character sprites in the game, with the background being the top left corner of a random map. There are 221 characters to choose from, though a good handful are duplicated, like the Scientist and the Receptionist. Also included are some objects (like the GR blimp) or animations (like the overworld map cursors).

Scroll forward/backwards with Up/Down, and exit with either A or B.

Clear Mail (メールクリア)

Refreshes the screen and deletes all mail, including mail currently being sent.

Tournament Table (トーナメント表)

Shows you the interface for the "Grand Master Cup Tournament Table" (グランドマスター杯トーナメント表 ). This option tests out the layout for the screen normally seen after each battle during the Pokémon Dome's Grand Master Cup. While in-game the listed names are that of the duelists the player faces against, here the game instead draws from an eclectic set of miscellaneous strings. The "duelists" are as follows: the player (here Mark / パーク), Status (ステータス), Psychic Battle (超バトル), Island of Fossil (化石のしま), Receive Pack (パック入手), Tech (研究員), Main Character (主人公), and Cancel (やめる).

Each time this option is accessed, a winner will be chosen at random, though the player's sprite will always be used to represent them. The progress each "duelist" made during the cup will also be randomized: in the above example, Cancel lost on the first round, but upon reloading the menu they may make it to the last round, or even win.

Send Mail (メール送信)

Opens a menu with the "Rocket's Sneak Attack" card illustration in the upper right corner, with it going away as soon as one chooses an option. A total of 16 choices are listed, with them being Game Center (ゲームセンター), Dr. Mason (Ｄｒ．オーヤマ), Biruritchi (ビルリッチ), Rod (リュウドー), and Ronald (ランド).

Confirm with A, and exit with B. Confirm will print the debug option's name in the text box at te bottom, and the mail will be sent to your mail box afterwards (though you will have to reload the area by going to the overworld).

Adjust Chips (しょじきんへんこう)

Fuel your gambling addiction. Add/Subtract the number of chips you have by an increment of 10 with Left/Right, and 100 with Up/Down. Exit the menu with B.

Name Entry (なまえにゅうりょく)

Change your name through the same menu as the one brought up when first starting the game.

Staff Roll (スタッフロール)

The same option as the one from the start-up debug menu.

Exit (とじる)

Self-explanatory.

Scenario Debug Menu

The Scenario Debug Menu

That's right, there are no less than three separate debug menus in this game. Use the codes 116-0BB-F7A + A86-0CB-91C + 496-0DB-E63 + C96-0EB-5D5 for the "Scenario Debug Menu" (シナリオ デバッグ メニュー) to replace "Status" in the regular menu.

This is the least polished of the debug menus. Some options work, some sort of work, and some are just really confusing to use.

Modify Events (イベントを操作する)

This option lists a series of options at the bottom of the screen. Scroll through them with Left/Right (Up/Down acts as a "quick scroll"), select with A, and exit with B.

Some items in this menu work fine, others, not so much.

Event	Translation	Description
ゲームクリア直後にする	Right After Beating The Game	Select this and the game has been beaten in the blink of an eye. Everyone has been defeated, every path has been cleared, and the entire GR Island map is open. Only the Sealed Fort remains locked, since it requires defeating King Biruritchi a second time.
プレイヤーの性別を入れ替える	Swap Player Gender	When called from the menu, this option won't work properly. Your name will be replaced by the default male/female name, and your portrait will change, but it appears the command to change the overworld sprite is borked. Indeed, you will become frozen in place, and your sprite won't even update. Saving and reloading won't work either, though using the option again will revert everything to normal.
はじまりの島に行く	Go To Starting Island	Using the option and returning to the overworld will take you somewhere different. On TCG island you will be at the TCG Island Airport, and on GR Island you will be at the GR Psychic Stronghold.
GR団の島に行く	Go To GR Island	Using the option and returning to the overworld will take you somewhere different. On TCG island you will be at Dr. Mason's Laboratory, and on GR Island you will be at the GR Island Airport.
すべてのコインをゲットする	Get All Coins	Works as advertised.
すべてのメールを配信する	Deliver All Mail	This doesn't literally deliver all your mail, rather it will send 16 mail to your mailbox. Leave to the overworld and back to receive the first 8, delete them out and repeat to get the other 8. Note the game will freeze on the map (the first time) if you have mail in your box.
チャレンジマシンのデータを壊す	Reset Challenge Machine Data	Will reset both Challenge Machines' data. The first time you select either of them, it will give you a message saying that the data is broken, and to try and get a new score.
ふういんのトリデOPEN	All Forts Open	Causes ONLY the Sealed Fort to open.
GM杯開催(クリアデータのみ)	Hold The GM Cup (Clear Data Only)	Triggers the Grand Master Cup at the Pokémon Dome, which normally is only accessible after winning 10 times in a row in Link Battles.
すべてのカードを10枚ふやす	Get 10 Cards	You get 10 more of every card, including energy cards.
エネルギーカードを10枚ふやす	Get 10 Energy Cards	You get 10 more of every energy cards.

An option which lets one edit all of the game's story progression flags. Each one can be set to either ON or OFF.

Modify Counter (カウンタを操作する)

To do: Identify the purpose of each value.

An option which lets you edit the game's "counters", which seemingly work the same way as event flags. There are 62 counters to change, each with a given variable. Most values go from 0-255, though some have a much lower range, as low as 0-1.

For example, counter 4 seems to be associated with Ronald, with its variable going from 1 to 2 after he gifts the player a card at the beginning of the game.

Modify Card Count (カード枚数を操作する)

By far the most useful feature of this menu. This option lets you choose any card (out of 445) and specify how many you own. While flipping through the cards, pressing Start will test the "You got X Card!" popup, though you still need to manually give yourself that card.

Three values (F, D, and T) will be listed at the bottom: F shows how many of a given card you own, and T is used to see how many more of the same card you can add (with 99 being the max value). Value D, when used to subtract from 99, will give you the max number of a given card you can own at once (for example, Grass Energy has a value of 32, meaning the player can own 67 copies of this card).

Excluded from value F are the cards you get at the very beginning of the game. Their default "owned" value will instead be accounted for in D: for example, you start off with four Lv.10 Charmander, and this card id has its D value set to 4. This was likely done to avoid any issues that could arise from the player having no cards on hand at all.

Return To Game (ゲームにもどる)

Works as intended, simply closing the menu.

Pause Mode

The GameShark code 0101D3CA will cause the game to pause/unpause whenever the Select button is pressed (music will continue playing, though). This function was used for debugging purposes, as seen in unused leftover text:

Japanese	Translation
ポーズモードがONになりました SELECTでポーズがかかります	PAUSE MODE IS ON. PRESS SELECT TO PAUSE.
ポーズモードがOFFになりました	PAUSE MODE IS OFF.
