How to Change the Batteries in the EZ Flash Omega Flashcart

Introduction

The EZ Flash Omega is a popular flash cartridge designed for the GBA. This device allows gamers to play a wide range of GBA homebrew, games and homebrew applications by loading files onto a micro SD memory card. One of the key features of the EZ Flash Omega is its ability to save game progress, and use a Real Time Clock or RTC function, which is made possible by a battery inside the cartridge. Over time, this battery may need to be replaced to ensure proper functionality. This tutorial will guide you through the process of changing the batteries in your EZ Flash Omega cartridge.

Now, before we go further, it is important to note the following. If you are not someone who plays a lot of games or use apps that require the Real Time Clock, then there is never a need to replace the battery.  This is because the EZ Flash Omega actually saves your game saves to the micro SD card itself where you can back it up and copy it to your PC or MAC as a backup.

What You Need

1. EZ Flash Omega Cartridge: Your flash cartridge that needs a battery replacement.
2. Replacement Battery: Typically, the EZ Flash Omega uses a CR1220 coin cell battery.
3. Small Phillips Head Screwdriver: To open the cartridge.
4. Tweezers or Small Pliers: To handle the battery.
5. Soldering Iron and Solder (Optional): If the battery is soldered in place.

Steps to Replace the Battery

Step 1: Open the Cartridge

• Turn off your GBA and remove the EZ Flash Omega cartridge.
• Locate the screw on the back of the cartridge.
• Use the Phillips head screwdriver to carefully unscrew and remove the back panel.

Step 2: Access the Battery

• Once open, you'll see the circuit board. Locate the battery; it's usually in a visible and accessible spot.
• In some cases, the battery might be held in place by a metal clip or soldered directly to the board.

Step 3: Remove the Old Battery

• If the battery just slides out, then you don't need to worry about much. Just push the battery with a small tool.
• If the battery is in a clip, gently pry the battery free using tweezers or small pliers.
• If the battery is soldered, you'll need to heat the solder joints with a soldering iron and carefully remove the battery. Be cautious not to damage the circuit board.

Step 4: Insert the New Battery

• If using a battery clip, simply insert the new battery ensuring the correct polarity (the '+' side facing up).
• If the old battery was soldered, solder the new battery in place. Make sure the polarity is correct.

Step 5: Reassemble the Cartridge

• Once the new battery is securely in place, realign the cartridge casing.
• Screw the back panel back on.

Step 6: Test the Cartridge

• Insert the cartridge back into your Game Boy Advance.
• Turn on the GBA and load a game.
• Try saving your game and then restarting the GBA to ensure the save function works correctly.

Conclusion

Replacing the battery in your EZ Flash Omega flashcart is a relatively simple process that can be done at home with some basic tools. This maintenance ensures that your flashcart continues to function correctly, saving your game progress without any issues.

Remember, handling electronic components requires care and precision. If you're not comfortable with any step, especially soldering, consider seeking help from someone experienced in electronics repair. Enjoy your gaming sessions with your refreshed EZ Flash Omega cartridge!
