EZ Flash Vi quickstart guide

Getting up and running with your EZ Flash Vi involves a few simple steps. Follow this guide step-by-step to gain a good understanding of how the EZ-Vi works and you'll be up and running in no time.

This Quickstart guide assumes you are running Windows XP.

 

MicroSD choice

A microSD card with serial number "SD-C01G JAPAN" or "C04G JAPAN" printed on its surface is highly recommended. These are rebadged Toshibas and have proven to be fast and compatible. PNY, Kingston, Verbatim, Dane-Elec are companies which have been confirmed to use this card in some of their batches.

 

Format your MicroSD

It's always a good idea to start with a freshly formatted MicroSD card.

Windows Method

Short and simple, but may give some drawbacks.

  • Insert your MicroSD/SDHC into your PC.
  • Double-click "My Computer".
  • Right-click your MicroSD drive and choose "Format".
  • Under the "File system", MicroSD select FAT or FAT16; MicroSDHC select FAT32
  • Click the "Start" button.

This also works on Windows Vista Systems, no administrative rights required

Using Official SD Association Tool

Another way is to use official SD formatting tool developed by Matsushita Electric Industrial. It can fix various corruptions and follows SD specification for best compatibility and speed.

Quick summary:

"Generally, SD/SDHC Memory Card file systems formatted with generic operating system formatting software do not comply with the SD Memory Card specification. If you have formatted the card using the PC's standard formatting program, make sure to reformat using SD format to take full advantage of maximum SD Memory Card performance"
Q: What happens when I format an SD Memory Card with a standard PC formatting program ?
A: The SD host equipment may not be able to recognize the SD Memory Card. Writing data to the card may take longer than necessary and some functions may no longer work.

Downlaod and information

Note: Here you will format completly the microSD, so if you already have personnal data on it (games, saves, homebrews, pictures ...), please make a backup on your PC.

 

The EZ-Vi Kernel

The Kernel is the EZ-Flash Operating System. It's a good idea to update to the latest version for new features and bug fixes. The main part is the file named ez5isys.bin. It's the first file to be loaded from the microSD, so it's required. The second part is the GUI interface based on moonshell 2.0. It's located in EZ5shell directory and it is required.

Included in EZ5shell directory :

  • skin files (skinname.dat) that make up look and feel of the user interface (skin directory).
  • splash screens files (skinname_bottom.bin and skinname_up.bin) that change the 2 splash screens pictures at startup (skin directory).
  • splash animation (skinname.ani) that is played at startup (skin directory).

Installing the Kernel

Important note : you will need at last one game on your microSD. If you start your EZVi with only the kernel on it, it will crash because there is nothing to display on the browser window.

 

The EZ-Vi Firmware

The firmware is the code used by the main processor Xillinx inside the EZVi. It is stored in a stacked memory (flash + sram) next it. This code is often updated to improve the EZVi (new microSD support, bypass DSi firmware Anti-Piracy protection, improve read/write speed ...), so be sure to have the latest version. There is 2 models of EZVi : the (705) and the (805). You can find which model you have by simply open the system menu (hammer/screwdriver icon)

Updating the Firmware

First of all, be sure your DS is full recharged and don't turn-off power during this update. /!\

  • Visit the All you need for EZVi WIKI
  • Download the last firmware for your EZVi model
  • Unzip content to the root of your MicroSD card (check picture).
  • Insert your MicroSD into your EZ-Vi
  • Insert your EZ-Vi into your DS and turn it on
  • Touch the health screen warning
  • In the DS/Dsi Main Menu, launch the EZ-Vi
  • highlight the firmware file .NDS and launch it.
  • follow instructions

After updating, you can delete the .NDS file from your MicroSD

Important note : do not downgrade your firmware version or you will brick your ezvi. Tak bootstrap is not compatible with old ezvi bootstrap.

 

Add games (ROMs) to your MicroSD

  • Insert your MicroSD into your PC
  • Drag and drop your "game.nds" file to your MicroSD
  • IMPORTANT: Use only clean roms.

 

Running games

You are now ready to play some games:

  • Insert your MicroSD card into your EZ-Vi
  • Insert your EZ-Vi into your DS
  • Touch the health screen warning to skip it
  • In the DS/DSi Main Menu, launch the EZ-Vi
  • In the EZ-Vi menu, highlight a game using the D-Pad or touch screen arrows and press A to launch!

Savegame files are stored on your MicroSD card. You will find them stored in a folder called "SAVE". It's a good idea to regularly backup your "SAVE" folder to your PC.

 

Cheats

Installation

To use cheats you must have an ARDS database file copied into the EZ5shell directory. This file must be named USRCHEAT.DAT.

  • download the last USRCHEAT.DAT file version at All you need for EZVi wiki
  • uncompress the file USRCHEAT.DAT and copy it into EZ5shell directory
  • That's it

Activating:

To use cheats you must enable the cheat engine by touching the icon under game's picture (see EZ Vi settings). In rom settings window, turn ON the cheat field and press Y. When you select a game that has cheat codes, a new window will pop up and will list all the cheats available. Simply scroll down the list toggling ON any cheats you wants to use, use up and down arrows to go through list. Keys to open/close a tree are displayed on the bottom window. When you are done press Save and close rom setting window with A. Start your game, cheats code will be activated at once.

Additional EZ-Vi features

Multimedia:

You will not be able read any multimedia files directly under the kernel. To do so, you need to run an external homebrew Media Player developed by Moonlight, called Moonshell.

So, download this homebrew and install it on your microSD with the installer program provided (launch "set up.exe" file and follow instructions). Once installed touch the moonlight icon (see EZVi settings paragraph), Moonshell will start. Now you can run audio files, video files, picture files, txt files ...

To softreset from Moonshell and return to kernel, just press start key and validate "Return to system".
