Guides:TimoVM's gen 2 ACE setups
|
This is a guide on how to execute and/or exploit a glitch. For a more technical overview of the glitch involved, see Arbitrary code execution. |
Arbitrary Code Execution (ACE) is the use of glitches to force the game to execute custom code written by the player. This gives the player near-complete control of the game, allowing the following uses:
- Add any pokémon, regardless of version.
- Add any item to the item bag.
- Freely edit pokémon data, including giving a pokémon any move, editing stat experience and editing DVs to obtain shiny pokémon.
- Experiment with more complex behaviour, such as walking through walls or adding a run function.
- For Virtual Console versions, transfer pokémon that could otherwise not be transferred like Mew, the full Treecko line and Torchic.
- And many more uses.
This page provides ACE setups for every single language/version release of gen 2. All setups are tested to be compatible for both original cartridge and virtual console releases. Alongside that, they should work on most (decently accurate) emulators.
What does this set of guides install?
This set of guides will guide you through the process of setting up ACE for any language version of Gold, Silver or Crystal:
- How to obtain an initial ACE setup.
- Using that initial ACE setup, install a small mail writer program that allows quick installation of more complicated programs and scripts.
- Provide several useful scripts and programs that can be used in combination with the mail writer.
ACE for Gold and Silver can be set up after reaching Goldenrod City, requiring at least two badges. ACE for Crystal can be set up after reaching Cherrygrove City, requiring zero badges.
In addition, more technically demanding alternative setups exist for Gold and Silver that can be set up in Violet City, right after obtaining the first badge.

The following are guides that allows a faster setup on Pokémon Gold & Silver (from Violet City onwards instead of Goldenrod City). The drawback is that these are more technical to perform compared to the guides in the next table.

Mail writer applications
After setting up the Mail Writer, you can browse through the pages linked below that details the various applications. Versions of the included codes have been made for all versions and all languages.
Mail codes
Using the Mail Writer, you can easily write and execute small codes with various effects. The page itself offers a selection of preconfigured codes that can be immediately used once the Mail Writer has been set up and require little prior knowledge to effectively use.
RAM writers
The RAM writer is a complex program that allow you to both read from and write to memory using a simple graphical user interface. The programs linked on the page are quite large (between 288 and 320 bytes in size), requiring a bit of time to set up and are most useful for players who have some technical knowledge. In return, the RAM writer can be used at any time and offers a high flexibility in writing and executing custom payloads.
