GBA 32MB, 1Mbit Flash Save with RTC, Flash Cart (Works with Pokemon games)

(2 customer reviews)


This re-programmable Flash Cartridge allows you to play GBA games that support the 1Mbit flash saves such as all of the Pokemon games – Ruby, Emerald, Fire Red, etc, should work with hacks too and now has RTC support! Designed and made in Australia.

Out of stock due to the chip shortage. Parts supplier ETA is around April 2022. Sign up for a notification when you make a selection in the options.

Check the list of games we have tested below and any game without saves will work. Also check below on how to determine if your game’s RTC will work properly. You will need GBxCart RW to re-write this flash cart. New v1.1 PCB allows for a CR1616 or CR2025 tabbed battery.

Why did we make this cart when you can pick up an EZ-Flash instead? A few users requested it! Since it’s just a regular cart, you’ll boot straight into the game and you can power off your system right after saving.

Please note that the RTC chip appears to be sensitive to moisture levels of 50% or higher. If exposed to these environments for a few hours the RTC may stop ticking.

This cart should work on every system that supports GBA carts – GBA, GBA SP, GB Micro, DS, DS Lite and the Game Boy Player. This cart uses 5-10mA more compared to a regular cart. If you would like us to test a game, check the Game saves tested list below.

Comes in a generic GBA cartridge (various colours available) with no label. The board won’t fit in a genuine cartridge. Each unit is assembled in house and is tested on a Gameboy Advance. You can supply the ROM file for us to flash the cart if you like, it will be tested for 20-30 seconds to ensure it works and we will also testing saving too.

SKU: N/A Category:


Battery: CR1616 (should last 4-5 years) or CR2025 (should last 7-10 years)

The PCB finish is ENIG.

When you place an order, if you would like the flash cart to be programmed with a ROM, you need to supply it to us via email (you can reply to your order notification). It will be tested for 20-30 seconds on a Gameboy Advance to ensure it works, if it doesn’t work, we’ll contact you.

How to test if RTC will work:
Open the ROM file in VBA v1.7.2, use the space bar to fast forward the game until you get to set the clock. Keep holding down the space bar for 10 seconds, if the clock hasn’t advanced that means it will work in this cartridge as the ROM hasn’t been patched.

Saving in these games have been tested to work:

  • F-Zero – Climax (Jpn)
  • Pokemon Fire Red, Leaf Green, Emerald, Ruby, Sapphire (all should work with Pal Park)
  • Pokemon hacks – Gaia, Radical Red, Unbound v1.1.2, Crystal Advance (2021-01-08)
  • Pokemon Mystery Dungeon – Red Rescue Team
  • Super Mario Advance 4 – Super Mario Bros.
  • MegaMan Battle Network 4.5 with the ENG Patch (CRC32: 0A7D0372)

RTC in these games have been tested to work:

  • Pokemon Ruby, Emerald, Sapphire
  • Pokemon hacks – Unbound v1.1.2, Crystal Advance (2021-01-08)
  • MegaMan Battle Network 4.5 with the ENG Patch (CRC32: 0A7D0372)

RTC in these hacks don’t work:

  • Adventure-red-chapter-b15-exp-fix-c. Also the game is too large to fit, but the 15D (unofficial) will fit ok

If your game isn’t here, send a quick email to support@insidegadgets.com with the ROM file and ask us to test it.

    Absolutely MUST BUY for Pokemon fans!

    For the better part of a decade i have looked in search of reprogrammable carts that would work for the Gen 3 Pokemon games. My original ones have slowly been dying due to old age and each year are closer and closer to death.

    However due to the cart perfectly replicating the functionality, i was able to recreate the experiences of Fire Red, Leaf Green, Emerald, Sapphire and Ruby flawlessly by dumping my original games onto a set of these. Every single feature works!

    Trading/Battling with other repo/real carts work.
    Day night cycles work correctly due to the RTC.
    E-Reader works perfectly over link cable.
    Gen 4 Migration works! (Pal Park and Dongle mode)

    These work correctly as well for distribution carts, so if you want gen 4 Mystery Gifts you can have that. If you want Gen 3 distribution carts, these work. Everything works!

    I recommend choosing the RTC Components as need be, you only need them for Emerald/Ruby/Sapphire as Fire red and Leaf Green did not have RTC Functionality, and the distribution carts do not need this either.

    Thanks again to Alex and the team, so happy i committed to the purchase, think im going to get a few more so i can complete a full set of distribution carts as well!
