EZ Flash/IV/Homebrew

Homebrew for the EZ4 requires you to use ds.gba format. The ds.gba format is the same as .nds save a small GBA header that is attached to the rom. There are a few ways to do this: You can either grab a header and use something like the following MS DOS command line: copy /b homebrew.nds+header.gba newhomebrew.ds.gba

Naturally you would change the names to match, at this time the best way to get a GBA header is to generate one.

You can also use DSBuild, now it comes as part of the devkitpro tools but 20 megs for a file only a couple of KB is a bit of a time waste so here is a mirror: http://www.4shared.com/file/2228491/ef07d789/dsbuild.html

Alternatively you can try naming the file with a .bin extension.

The EZ4 has a DLDI patch available meaning most new homebrew will work and a lot of other homebrew has been recompiled to use it, there exists a reasonable amount of homebrew built prior to the introduction of DLDI with EZ4 specific compatibility.

For code that uses SRAM to save read the following thread SRAM issues with the EZ4

The following items have all been tested on an EZ4. For games & applications requiring Wifi Mario Kart DS was previously used to set up the wifi connection.

This section will mainly deal with homebrew applications and games, you are advised to have a look at emulation. dcemu is a good place to look for homebrew code until this page is up and running.

Please note: This information is not to be meant a repository for homebrew development. This is not a news site and updates may not be frequent. It is designed to help users determine which Homebrew game or application will work with the EZ4 carts. Contributions and submissions from other users are appreciated.

If you are interested in developing for the EZ4 it can use both the GBFS or equivalent method of DS homebrew and there is support for DLDI, see the Developers page for more infomation.
