Beginner's Guide To The EZ-Flash 3in1

The EZ-Flash 3in1 is a slot 2 expansion pack originally made as a sidekick to the EZ-Flash V for use on the Nintendo DS lite, but with the release of the source code other flash cart can use this awesome slot 2 expansion. It's called 3in1 because it has GBA, RAM, and RUMBLE.
This is a beginner's guide aimed at those who are new to the EZ Flash 3in1.

What you need to get started

• A slot 1 flash cartridge (R4, Acekard, etc)
• The EZ-Flash 3in1.
• GBAExploader, you can download it here: http://filetrip.net/file.php?id=10382
• And yes, you will need a DS lite.

1. Download GBAExploader and extract/unzip it to your computer.




2. Copy and paste these 2 files to the root of your microSD memory card.
GBA_Exploader.nds and GBA_Exploader.ini




3. Create a folders in the root of your microSD memory card and name it “GBA”.
GBAExploader will generate these two files (GBA_SAVE & GBA_SIGN) the first time you start up GBA_Exploader.nds




4. Copy and paste your (unpatched) GBA games into the “GBA” folder
Each time you run a game GBAExploader it will automatically patch it for you.

5. Launch GBA_Exploader.nds, pick your game and enjoy.





There are a few flash cart that can play GBA games without the need for programs like GBAExploader, but you will still need the EZ-Flash 3in1 or similar slot2 cartridge.
Here's a few of them:

• Acekard 2i with AKAIO
• WOOD R4
• cycloDS iEvolution
• M3
• iEdge
• EZ Flash Vi
• iSmart Premuim

Using the EZ Flash 3in1 with these flash cart are pretty easy. Here's a few quick mini guide.










I will add a few more at a later time.





Everything is stored in your microSD memory card of your slot 1 cartridge, except for games that are written to NOR.

There is 3 mode, PSRAM, NOR, and EXPANSION.

• PSRAM Mode
  Most games (16mb or less) should be run from PSRAM.
  PSRAM is temporary memory, from which the game will disappear after powering off
• NOR Mode
  For some games (32mb) you’ll have to write them to NOR before you can play them. A few example is Kingdom hearts and Mother 3.
  NOR is semi-permanent memory which will allow your EZ-Flash 3in1 to mimic a real GBA cartridge.
• EXPANSION Mode
  Here, you can adjust rumble level and stuff. When you’re done it’ll soft reset back to to your slot 1

GBATA is a gba rom tool with the functions below.
1. Header Viewer
2. Intro Remover
3. Overdump Fixer
4. fix header
5. Intro Drawer
6. IPS Patcher
7. SRAM Patcher
8. Rom Trimmer

thanks mate, that's a solid guide you got here.
makes me want to buy one to relive the good old GBA days

Awesome tut. Might be worth noting that you can use a DS Phat with the Phat version of the EZ-Flash 3in1 as well. In fact, I purchased mine from realhotstuff.com.

might as well mention the 3in1+ nds  backup tool, that can be used to dump roms and savs from retail carts and also load savs to retail carts, simpler to use then the wifi nds backup tool

Well,thanks for your detail summary,it is helpful.
