Guides:Coin Case ACE

This page explains how to set up a Coin Case ACE setup that doesn't require a slide pokemon or Wooper/Quagsire. It instead makes use of a pokémon that has gained specific stat exp.

Explanation

When using the modern Coin Case setup, where a Bellsprout/Machop's cry and specific newly loaded tiles are buffered in memory, the game will jump to the $FA98-$FA9B range, which is echo ram containing the stat exp data of party pokémon #3.

Using specific stat exp values, we can form a jump to $CF00, which is located in the latter half of the current buffered mail. This gives us barely enough space to fix the stack and jump to the start of box names, resulting in a Coin Case ACE setup that is compatible with Wrong Pocket TM ACE box name codes.

This setup is specifically meant for new game scenarios, it is intended as a starting point for an easy setup, which can then be converted into a more universal Wrong Pocket TM setup.

Building the setup

• Start the game as normal, you are free to pick any starter you want.
• When you arrive at route 34, catch any Drowzee.
• Pick up the Coin Case after you arrive in Goldenrod City.
• Using the Drowzee you caught, defeat only the following pokémon. The order in which they are beaten doesn't matter but the Drowzee has to defeat them by itself, without sharing experience with other party pokemon.

Drowzee	Found on Route 34 with 50% spawn odds, any time of day.
Oddish	Found in Ilex Forest with 50% spawn odds, only during night time.
Nidoran♀	Found on Route 35 with 30% spawn odds, any time of day.
Nidoran♀	Found on Route 35 with 30% spawn odds, any time of day.

• Buy any kind of mail (Flower Mail can be found in Goldenrod Dept. Store) and give it to your Drowzee with the following content:

• Go to the Goldenrod pokémon center and rename the first box name to the following:

• While still inside the Goldenrod pokémon center, make sure to save, then exit and take 4 steps to the right.
• Open the start menu, then listen to the cry of either Bellsprout/Machop.
• Go to the Pokémon menu and reread the abovementioned mail.
• Open the item bag, switch item pockets at least once, then use the Coin Case.
• You can verify that the setup works by checking the TM/HM pocket. you should now have 255 TM03's.

Using the setup

Now that you have set up everything, you should be able to use (nearly) all box name codes that are intended to be used with Wrong Pocket TM. In particular, you can use it to build and install a RAM writer program, which you can use to replace your current setup with one that can be used anywhere at any time.

In order to use the Coin Case ACE setup:

• Go to the Goldenrod pokémon center and rename box names according to the box name code you wish to execute.
• While still inside the Goldenrod pokémon center, make sure to save, then exit and take 4 steps to the right.
• Open the start menu, then listen to the cry of either Bellsprout/Machop.
• Go to the Pokémon menu and reread the abovementioned mail.
• Open the item bag, switch item pockets at least once, then use the Coin Case.
