• A 3DS with CFW (Custom Firmware)
  • https://3ds.hacks.guide/ has instructions for installing CFW
• 3DSRNGTool
• PCalc
  • Ultra Sun/Ultra Moon
  • Sun/Moon
• The honey item
• Have started an Island Scan and know the Pokemon you've scanned for
  • List of Island Scan islands and days for USUM

Step 1: Setup PCalc

To start, make sure PCalc's wild view and game view are open.

Step 2: Setup 3DSRNGTool

Open up 3DSRNGTool, then follow these instructions to set it up properly:

In the upper right of 3DSRNGTool

1. Type the Init Seed PCalc shows into the Seed box in 3DSRNGTool.
2. Change the Game Version dropdown to be the game you're currently playing.
3. Change TSV to be your game's TSV.
4. If you have the shiny charm, make sure the Shiny Charm box is checked.

On the left of 3DSRNGTool

1. Click the Wild RNG tab.
2. Change the Category dropdown to say Island Scan.
3. Change the Pokemon dropdown to be the Pokemon you are targeting.

On the right of 3DSRNGTool

1. Follow the timeline guide using the NPC Count PCalc shows for the number of NPCs. Wait at least 30 seconds after bringing up the window to allow for the NPC counter to calibrate correctly.
2. You should now have a target frame you wish to hit.

In the middle of 3DSRNGTool

1. Change the IVs to be what you want for the Pokemon.
2. If you want a shiny Pokemon, make sure the Shiny Only box is checked.

Step 3: The RNG

If you've been following the guide step by step, you should now:

• Have made a timeline
• Have a target frame
• Be standing in the area you want to catch your Island Scan Pokemon in
• Have the honey item

Hitting your target frame

1. Press X to open up the in game menu.
2. Hold your game's cursor on the bag option.
3. Watch the Frame counter on PCalc.
   • When the Frame counter is close to your target frame, press Start + Select to pause the game.
   • Press Select multiple times to slowly advance the frames to your target frame.
4. Once you have reached your target frame, press and hold A to have PCalc unpause the game while you enter the bag.
5. Find and use the honey item to start a wild encounter.
6. If the Pokemon you ran into was not the Island Scan Pokemon, see how many frames off you were and adjust.
   • You can do this by searching all frames for the Pokemon's IVs you did get. Check the frame range instead of timeline and search using the IVs of the Pokemon you got.
   • After finding what frame you actually landed on, subtract or add as necessary from the delay and restart from the beginning.
   • This should not happen too many times.
