Attorney Online (AO for short) is an online roleplay chatroom game based on the Ace Attorney universe. Created by FanatSors in 2013, this community has thrived for over a decade.
This is an unofficial port/recreation of the PC client to the Nintendo DS. It also works on DSi and 3DS.
Features
- Supports playing MP3 files for music. (22050 Hz, 80 kbps).
- Can connect to AO servers that utilize the WebSocket protocol, as used in the game's web browser version (webAO).
- Supports custom AO content, including those of sprites of 3DS characters. (Must be converted beforehand using the converter tool).
- Ace Attorney-like UI, as if you were playing the original DS games.
- Uses stb_truetype, which renders TTF fonts for the most accurate Ace Attorney text visuals. ("Igiari" font belongs to Caveras.)
Installation
Download the NDS ROM and vanilla-data.7z from the release page.
The release comes with the vanilla data so it's recommended to start out by connecting to the AO Official Server.
On melonDS
- Go to Config > Emu settings > DLDI.
- Tick "Enable DLDI (for homebrew)".
- For SD card image, write "melonDS.img" as the file name.
- Leave "Read-only SD" disabled.
- Set image size to whatever you prefer. At least 512 MB is needed to store the vanilla data.
- Create a new folder in the melonDS folder named "dldi", Enable "Sync SD to folder" and set it to that new folder.
- Extract the "data" folder in vanilla-data.7z to the dldi folder.
- Put the NDS rom anywhere and run it in melonDS.
- Tutorial on how to Connect to WFC in MelonDS.
On a DS, DSi or 3DS (SD card)
- Insert the SD or microSD card in your computer.
- Extract the "data" folder in vanilla-data.7z to the root of the SD card.
- Put the NDS rom anywhere in the SD card.
- Remove the SD card, put it back on your flashcard/DSi/3DS and run the ROM.
- If you can't connect to Wi-Fi, check your WFC settings using a retail DS game, or on the system settings. Try using your phone as an unsecured hotspot.
Converter tool
You can use the AO NDS converter tool to bring custom content from the PC version of Attorney Online to AO NDS.
You must have installed Attorney Online on your PC beforehand. The easiest way to install it is by using the AO launcher.

Changelog
v1.2 2024/06/02
Client:
- Fix random crash when interacting with server areas, particularly those that make use of "hubs".
- Performance boost on scrolling through music list, IC and OOC chat logs, and evidence description.
- Chat logs are no longer limited to 100 messages.
- Fix music list not scrolling back to the beginning when using the search function.
- Evidence subdirectories are now loaded into cache on game startup.
- Added certain checks when loading a character's char.ini file to avoid a crash.
- Try to improve RAM management with character emotes and sounds.
- When loading a character emote, the current sound is unloaded from memory first, then the new character image is loaded, and if available, the new sound is loaded afterwards.
- For character images that are LZ77-compressed (those that have stream = 0 on nds.cfg), instead of loading the entirety of the compressed data into memory and decompressing that, it is decompressed through streaming, only taking up 4KB of RAM while doing so (see arm9/source/global.cpp for more info if interested).
- It is now possible to select between all of a character's custom shouts on the "Talk (IC)" screen
- Speed up re-displaying the "Talk (IC)" screen when the keyboard is closed.
- Attempt to speed up scrolling through emotes on "Talk (IC)" screen.
Converter tool:
- Subdirectories on evidence images are now converted.
- Backgrounds with .webp, .gif and .apng formats are now converted.
- Character conversion should now be slightly faster due to using python's built-in multiprocessing library instead of third-party library joblib.
- "Failed to convert" messages will now be logged to a file.
- When converting character emotes, the converter will now try to read the image file's header to determine its' true format (e.g. There could be a .apng file that is actually a gif).
- A character's custom shouts will now be resized to 256x192 if necessary.
- Sounds and blips are converted to 22050 Hz instead of 32000 Hz to save on RAM.
- If you are updating the game, it's recommended to download vanilla-data.7z and install the new sounds.
v1.1 2024/02/03
- Fix crash when loading the public server list due to a server missing its' description field.
