Gameboy 64MB Mighty Flash Cart

$45.00

  • Near instant game loads (2-5 seconds, it just reboots the Gameboy)
  • 64MByte storage space
  • 128KB SRAM
  • 8 Save slots (on by default)
  • Easy to use drag & drop GUI for loading ROMs

Limitations

  • 140 ROM file limit
  • Windows OS required
  • The 128KB SRAM is shared between all games – your save progress can be wiped if you load the wrong game
  • Take approximately 50 minutes to write the whole 64MB, it isn’t very fast
  • If you want to add games to the existing games on the cart, you have to re-write the whole cart
  • To use all 64MB and keep your saves slots in-tact you need to use GBxCart. Otherwise you are limited to 8MB with other flashers and your save slots will be wiped.

This re-programmable Flash Cartridge gives you 64MB to load your ROMs, you can enable the save game manager to allow you to save/restore to 8 slots and you can simply drag and drop your ROMs to our GUI to generate the ROM file to flash.

Allows you to play most Gameboy/Gameboy Colour games including Pokemon (no RTC support), Zelda, Wario Land, LSDJ, etc.

Questions? Jump on our Discord server where we and other users can help you or contact us via Twitter.

At this time, this flash cart can only be used with our GBxCart RW flasher if you wish to write more than 8MB to it or want to keep your save slots in-tact.

This cart works on every Gameboy system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player. If you would like us to test a game, please send a quick email to support@insidegadgets.com.

Check out the cart comparison image to see how each cart compares to each other and the clone carts.

Comes in a generic clear or grey Gameboy cartridge with our label. 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.

Description

Specs
ROM: 64MB Flash (S29GL512)
SRAM: 128KB battery backed with a CR2032 (should last 10 years or more)
MBC: MBC5 by default. Use the loader to allow for MBC1/3 games and to use this cart as a multi-game cart.

The PCB finish is ENIG, Gold fingers (on the edge connector) with a 45 degree bevel to give the maximum life for insertion/removal of the cartridge.

Low power at ~20mA current consumption (Tested on Pokemon Crystal start up screen). Will work for LSDJ too.

When you place an order, if you would like the flash cart to be programmed with a ROM (or your generated output.gb file), you need to supply it to us via email through a link such as Dropbox or Mega (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. If you don’t specify a ROM, it will be loaded with the LSDJ Demo.

Wish list / Ideas

  • Have it able to load additional games without re-writing the cart
  • Have a save slot per game so when loading a different game, it will save the SRAM to that games save slot and load the other games save slot to the SRAM

How to use

Open up the insideGadgets 64MB Mighty Flash Cart Multi-Game Maker.exe file. You can simply drag and drop your ROM files to it and move items up or down or remove them.

By default the save slot option is enabled, disabling it will allow you to have 1MB more space. The “Use faster writes” can sometimes be hit or miss but you will know within 10-20 seconds of no progress, please power cycle the flasher and try again. You can select the “Backup Save Slots” option to backup your save slots to a folder with the current date/time and each save slot will have the save name you gave it.

Once you have added the files you wish, press generate and a pop-up window will appear briefly and it will generate an output.gb file. After that, if you have GBxCart RW plugged in, you can press Write to Cart and it will flash the output.gb file to your flash cart. If save slots are enabled, it won’t overwrite the save slot data on the cart.

Using the Multi-Game Loader

Once you boot your Gameboy, you can use the up/down arrow to scroll through the list or left/right to jump by 10 places. Press A to launch the game – the Gameboy will restart and the game will be loaded.

After you play a game and power off the system, when you power it back on, you will automatically jump to the last game you played (has an asterisk next to it to show this). This is done so it’s less likely for you to load a different game by accident and lose your save data if you haven’t backed it up.

Using the Save Manager

If you enabled save slots, you will have access 8 save slots by pressing the Start button at the loader screen.

To save the RAM to the slot, select the “Save” option, press A and then press Select to confirm. It will take about 20 seconds to save.

To load the slot into the RAM, select the “Load” option, press A and then press Select to confirm. It will take about 10 seconds to load.

To erase the data current on the SRAM, select “Erase” option, press A and then press Select to confirm. It will take about 10 seconds. Be careful about using this option as it will wipe your save. This is available because certain games like Perfect Dark can become corrupted or not work properly if the upper 32KB of the SRAM contains data.
