GBA 3-in-1, 32MB (x3), 1Mbit (x3) Flash Save with RTC, Flash Cart (Works with Pokemon games)


This re-programmable Flash Cartridge has a 3 position switch which allows you to change between 3x 32MB games and 3x 1Mbit flash saves so you could have R/E/S all on the one cart. 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.

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.

The CR2025 will make the cart shell bulge slightly. The cart shell is not modified for the switch so you will need to perform some cuts/filing to it if you want to access the switch from the outside. 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.

SKU: N/A Category:


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

The PCB finish is ENIG.

How to re-write the cart:
Make sure you are using the Flasher v1.47+.
Select the GBA 32MB / 3-in-1 option and choose your rom file as normal.
Once the flashing is complete, flick the switch and flash your next file.

RTC time is incorrect after restoring a save
You can either choose to remove the RTC offset on the save file or change the RTC offset to match the other save files. If you choose to remove the RTC offset, it will have to be done for all save files and then run the: GBxCart Read/Write GBA Cart’s RTC v1.0 program

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.
