Summary of "How to Get INFINITE AFK Money in Pokémon FireRed & LeafGreen"

Quick summary

This shows a method to farm large amounts of money very early in Pokémon FireRed / LeafGreen (on Nintendo Switch) using the Nugget Bridge Rocket Grunt, and how to automate it AFK with a third‑party macro controller. No game mods or risky glitches are required.

Core method — Nugget Bridge exploit

Location: Cerulean City, Nugget Bridge (the Rocket Grunt near the top).

Steps

Bring a very weak Pokémon.
Talk to the Rocket Grunt at the top of the bridge and accept the free Nugget he gives.
Intentionally lose the fight (white out at the Pokémon Center).
After reviving, repeat the process.

Notes

Do not beat the grunt — if you win the battle you cannot repeat the gift.
Each Nugget sells for about 5,000 Pokédollars. Repeating yields large sums quickly (example: 24 nuggets → ~120,000 Pokédollars). You can farm overnight to amass many more.

Automating AFK with a macro controller — step‑by‑step

Hardware

You must use a third‑party macro controller (the standard Switch Pro Controller has no macro feature).
Recommended controllers mentioned: Ghouly Kit K3 Pro (~$50) and 8BitDo Ultimate 2 (~$70).

Recording a macro (general flow)

Start recording the macro (hold the macro button ~3 seconds to begin).
Wait briefly after leaving the Pokémon Center (helps avoid missed frames).
Walk to the Rocket Grunt and trigger dialogue — press/“spam” A where appropriate to accept the Nugget.
Allow the fight to run until your Pokémon faints (account for move length — e.g., Ekans wrap/poison/bite can vary).
Let the white out occur and Nurse Joy heal your party.
Spam B to clear text boxes and exit menus.
Return to the starting position so the loop can repeat.
Stop recording (press the macro button once). Double‑tap the macro button quickly to loop the recording infinitely.

Macro button usage

Hold ~3 seconds to start recording.
Press once to stop recording.
Double‑tap quickly to loop the recording indefinitely.

Tips while setting the macro

Expect trial and error to get timing right because enemy move lengths and RNG vary.
Include at least one heal action or extra delay in the macro if battles sometimes take longer.
Monitor the first few loops to ensure the macro never accidentally beats the grunt or gets stuck.
You can leave it running overnight for a very large haul (up to 999 nuggets if you want to farm that much).

Why this works / notable cautions

This relies on the NPC repeating the item gift if you do not defeat them — no risky glitches required.
Be careful not to defeat the Rocket Grunt (you must white out).
Macro controllers are third‑party purchases; ensure compatibility with the Switch/Bluetooth and read product documentation.
RNG in battles (e.g., Ekans moves) can change timing — build buffer/delays into your macro to account for variability.

Results shown

Example run: 30–60 minutes yielded 24 nuggets → sold for roughly 120,000+ Pokédollars.
Practical uses for the money: buy Poké Balls, TMs, potions, vitamins, or coins at the Game Corner.
