Wabbit DS
Author(s)James Montelongo

DCEmu Webmaster Wraggster announced that Homebrew Developer JimE has come out with WabbitDS, a TI-83+ Emulator. For those unfamiliar with TI-83+, it is a graphing calculator released by Texas Instruments and allowed for coding in both TI-BASIC and machine code.

The developer placed in a few nifty features in the application that make it easier to use. In addition, to the basic functions as a graphing calculator, Wabbit DS also has a disassembler and a rotatable GUI. This program is pretty simple to use with customizable key configuration options and full touchscreen support. Here are the other changes in the program:


  • ROM\8xu loading
  • Rewinding\Fast Forwarding
  • Rotatable Interface (ie portrait mode)
  • Touchscreen Interface
  • Disassembler
  • Key Configuration
  • Sleep Mode
  • Fast Application Loading
  • Perfect Gray Scale for Gaming


  1. Patch WabbitDS.nds with your cards dldi patch.
  2. Make sure to have a TI-83+ rom some where on you card with the extension "*.rom". If you own a TI-83+ but are unable to dump a rom from your calculator, you may use TI's OS updates. These have the extension "*.8xu" and are freely downloadable from TI's website under the condition you own the calculator.

User Guide

On first start you will be prompted to select your rom. Once loaded the rom is made into a save file(extension "*.tisv"). You no longer need the origainl rom file, the save file includes all flash memory.

Do NOT distribute save files. After the first running of the emulator a file called "TIDS.CFG" is written to the default fat device. It contains the settings for current save state, key configuration, rotation and other info. Should you wish to have a clean start that file need only be deleted.

Select while the emulator is runnig - opens the main menu. You have the options Key Configuration, File Sending, Rom loading, and Disassembler. Pressing B or Select exits. You may use the D-pad or the touch screen to navigate.

Key Configuration lets you change what TI keys buttons A, B, X, Y, Start, and D-pad maps to. This is done by scrolling through a list for now. Select exits back to the emulator and B returns to the menu screen. Pressing Start will set the keys to their Default settings.

File Sending lets you send TI varibles to the emulated calculator. Applications(*.8xk) may occasionally require you to delete old apps of the same name, or reset the ram. Typically this isn't required. For linking you must be on TI's Homescreen.

Rom loading lets you load a new rom, save, or 8xu file. Do not try loading 8xu or rom files that were not meant for the 83+, it simply won't work.

Disassembler it is a bit buggy and limited but its still functional. A steps, X trys to step over, and Y trys to run to cusor. Select exits back to the emulator and B returns to the menu screen.

In the File browser,

Double click - open folder or to load a file.

Drag the screen/ scroll bar - scroll up and down. Dpad/ A button can also be used.
