INTRODUCTION
The EZ-Flash 3in1 is a slot 2 expansion pack originally made as a sidekick to the EZ-Flash V for use on the Nintendo DS lite, but with the release of the source code other flash cart can use this awesome slot 2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.

Each time you run a game GBAExploader it will automatically patch it for you.

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



Flash cart that does not need GBAExploader

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.
1. Make a “GBA” folder in the root of your microSD memory card
2. Copy and paste your GBA roms into that “GBA” folder.
3. Put everything back into your DS and turn it on.
4. Go to your “GBA” folder and open it to see all your roms
5. Just click on the game you want to play and WOOD will do the rest

Note:
You can select Ram or NOR by pressing (Y) when the rom is highlighted.
WOOD only support the older EZ Flash 3in1
If you have a newer EZ-Flash 3in1, than use GBAExploader.

1. Make a “GBA” folder in the root of your microSD memory card
2. Copy and paste your GBA roms into that “GBA” folder.
3. Put everything back into your DS and turn it on.
4. Go into the cycloDS iEvolution’s settings menu.
5. Scroll all the way to the bottom and enable “GBA Support”. While in the settings menu you can set your rumble to your desire rumble strength .
6. Go to your “GBA” folder and open it to see all your roms
7. Just click on the game you want to play and the iEVO will do the rest.

NOTE(1):
You can select Ram or NOR by pressing SELECT

NOTE(2):
For the "original" cycloDS, the OS (firmware) is almost the same as the cycloDS iEvolution, so the process is the same as the cycloDS iEvolution.
Just follow step 1-7 in this spoiler.

1. Make a “GBA” folder in the root of your microSD memory card
2. Copy and paste your GBA roms into that “GBA” folder.
3. Put everything back into your DS and turn it on.
4. Go to your “GBA” folder and open it to see all your roms
5. Highlight the game you want to play and press (A). You will be given 3 option
(X) NORFLASH
(B) Cancel
(Y)PSRAM
Select the option you want, and your game should start.

NOTE:
You can set the rumble strength in the settings of the EZ5i.

Should be the same as the cycloDS

Same as EZ5i

I will add a few more at a later time.



Helpful Tips & Random Stuff

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

Has anyone gotten the 3in1 to work with RetroGameFan's YSMenu (https://gbatemp.net/threads/retrogamefan-updates-releases.267243/)?

Games like Pokemon FireRed get a white screen unless they're sram patched. If they are patched, the game says the save is corrupted, but it seems to load and save fine.

Metroid Zero Mission and Kirby Nightmare in Dreamland save and load fine without patching.

None of the saves generated by YSMenu are compatible with emulators.
