Codes target the USA/Europe Game Boy Color release. Enter multi-line codes as separate lines, or as one combined entry if your cheat menu requires that format. Replace xx on hour and minute codes before enabling them.

Device families

GameShark, PAR, Game Genie, and Codebreaker

Match the device family before you type. The same effect can look completely different across formats.
Main format

GameShark / Pro Action Replay

These codes use the 8-digit Game Boy Color format (for example 910992CF). Multi-line codes such as Infinite Gold need both lines active at once.

  • Works on many GBC flash carts and emulator cheat menus
  • Hour and minute modifiers use replaceable xx values
  • 25 copyable codes in the browser above
Limited set

Game Genie

Game Genie uses a different hyphenated format. Ready-to-copy Genie codes for this title are sparse, so prefer GameShark/PAR for bait, hooks, gold, and time control.

  • Different hyphenated format from GameShark
  • Region and cartridge version must match
  • Use only if your hardware requires Genie codes
Limited coverage

Codebreaker

Dedicated Codebreaker codes for Legend of the River King 2 are uncommon. If your device accepts Game Boy Color GameShark-format codes, use the GameShark/PAR set instead of converting formats by hand.

  • Do not mix formats in one session
  • Confirm the device’s GBC code type first
  • Disable everything if the game freezes at boot

Play clean when you can

No-cheat tips that solve the same problems

Most players searching for codes only need better timing, the right early bait, or a reminder not to sell a quest fish.
Catch timing

Wait for the continuous tone

Separated chimes mean the fish is only circling. Press A when the sound becomes one steady tone, then stop reeling while the fish runs and resume on rests.

Open fishing guide
Best early bait

Start with Earthworm + Hook(S)

The Kid and Teen openers equip T.Rod(S), Earthworm, and Hook(S). Earthworm is the cheap freshwater starter bait and covers many early Lake and Stream targets without a “have bait” code.

Browse gear prices
Time windows

Use the hour modifier only when waiting hurts

If you need a night or midday window, the hour and minute codes save real time. Otherwise rest at inns or walk until the on-screen clock reaches the fish’s period.

Check fish periods
Save battery

Protect the battery-backed save

The USA cart uses MBC5 + RAM + battery. Save often, avoid powering off while the save icon is active, and keep a spare save slot before risky cheats or long king fights.

Battery & save notes
Softlock avoidance

Keep exchange fish and key gear

Do not sell the first route exchange fish (for example the Kid route Sucker Eel / S.Eel) before the NPC trade. Item cheats can refill bait, but they cannot restore a missed story exchange.

Open walkthrough
Better rods

Upgrade when the T.Rod feels stuck

A T.Rod cannot pull the line in on demand. After the first money loop, buy a Surf Rod or Lure Rod so you can retrieve line with B and open more tackle options.

Entry checklist

How to enter a code without wrecking the save

  1. 1

    Confirm the release

    These codes target the North American / European Game Boy Color build (dual-mode, Super Game Boy enhanced). Japanese or remade versions may need different addresses.

  2. 2

    Back up the slot

    Copy the in-game save to a free slot, or export the battery file from your flash cart or emulator before enabling anything.

  3. 3

    Enter every line

    Codes such as Max HP and Infinite Gold need both listed lines. Incomplete multi-line codes can do nothing—or worse, write partial values.

  4. 4

    Fill hour and minute values

    Replace xx in 91xx0ED0 with hour 00–0C, and in 91xx0FD0 with minute 00–3C. Do not enter the letters xx literally.

  5. 5

    Test off the critical path

    Enable the code on a backed-up file, walk around, open the inventory or status screen, then disable the code and save again if the result looks right.

  6. 6

    Prefer the field guide for progression

    If you only needed a code because a fish would not bite, switch to the fishing guide and walkthrough rather than stacking more modifiers.

Common problems

FAQ for code users and stuck anglers

I can’t catch any fish. What am I doing wrong?

Ignore the separated circling chimes. Press A on the continuous tone, then stop reeling while the fish escapes. Confirm Hook(S/M/L) and bait match the target. Codes will not fix wrong timing—use the fishing guide for the full loop.

Where can I get a better fishing rod?

Start with the free T.Rod(S). Freshwater tackle shops sell larger T.Rods, Surf Rods, Lure Rods, and Fly Rods after you raise gold from fish, bugs, or flowers. Check the tackle guide or gear catalog for shops and prices.

How do I unlock the Ocean area?

Ocean access comes from story progress, not a code. Follow the Kid or Teen walkthrough until the route opens Shore/Ocean travel instead of forcing progress with a memory editor.

Do these codes work on 3DS Virtual Console?

The historical 3DS Virtual Console release does not accept cartridge GameShark devices. Use original hardware or a flash cart with cheat support for the codes on this page. Keep a clean save if you care about challenge or achievements. See how to play today for legal play paths.

Is there an auto catch fish code?

No ready-to-copy auto-catch code is listed here. Use bait and hook codes if you need inventory help, but still set the hook on the continuous tone. For the full rhythm, open the fishing guide.

Is there a code for unobtainable items?

This list covers bait, hooks, gold, HP, experience, and clock modifiers only. Story maps, king fish, and quest progress are not unlocked by these codes. Use the walkthrough for progression blockers instead of hunting obscure item codes.

Is Infinite Gold safe for shops?

It is one of the least invasive codes for shopping, but huge balances can hide natural economy pacing. Prefer targeted bait or hook codes if you only need one missing item.

What if a code does nothing?

Confirm the USA/Europe GBC build, enter every line, disable conflicting codes, and soft-reset after enabling. Some menus need the code active before the title screen; others apply only in-game. If nothing changes, turn the code off and restore your backup.
