Gameboy 1MB 128KB SRAM Flash Cart (Great for LSDJ) [Discontinued]

$27.00

This re-programmable 1 MByte Flash Cartridge allows you to play most Gameboy/Gameboy Colour games including Pokemon (no RTC support), Zelda, Wario Land, LSDJ, etc and allows you to re-flash it with any flash cart programmer like GBxCart RW that supports the MX29F800C. It also allows for some MBC1 games (only on firmware R1 or R1.1) that don’t work properly on clone carts such as Super Mario Land 2, Donkey Kong Land 3, Megaman 5 to name a few.

LSDJ users should select the MBC5 only firmware option. Works with GB Studio v1.1.0 with saving if you wish to develop your own game.

We highly recommend the 1MB Ultra Low Power Flash Cart instead unless you require MBC1 support.

Check this list of Gameboy games to see the ROM/RAM size and MBC type your game will have. This cart works on every GB system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player.

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

We have different firmware available for different use cases:
MBC5/3/1 Hybrid (R1) – I want to play a good amount of old and most new games
MBC5/3/1 Hybrid + MBC1 1MB (R1.1) – I want to play more old games and most new games (slightly higher power consumption)
MBC5 only (R1.2) – I only want to play new games and use LSDJ

Once the firmware has been written, it can’t be changed. If you would like to change the firmware version, you can contact us and send the cart back to us for re-programming.

Description

Specs
ROM: 1MB Flash (MX29F800C)
SRAM: 128KB battery backed with a CR2032 (should last 10 years or more)
MBC: MBC5 default (with some MBC1 support) emulated with a Altera CPLD

MBC5/3/1 Hybrid (R1.0a):
MBC5 – Bank 0 gives bank 1 like in MBC1/3. Hybrid support for MBC1/3 games.
MBC1 support is limited to 512KB ROM / 8 KBytes RAM, it’s locked in “ROM Banking Mode” but without the 1MB ROM support.
Uses 43-54mA more compared to a regular cart.

MBC5/3/1 Hybrid + MBC1 1MB (R1.1a):
Same as R1 but add the 1MB ROM support to the MBC1 implementation (only tested with 1 game). The games that need this usually Japanese/Chinese games.
Uses 48-58mA more compared to a regular cart.

MBC5/3/1 Hybrid + MBC1 1MB (R1.1b):
Same as R1 but add the 1MB ROM support to the MBC1 implementation and 32KB SRAM (only tested with 1 game). The games that need this usually Japanese/Chinese games.
Uses 48-58mA more compared to a regular cart.

MBC5 only (R1.2a):
Implements MBC5 only.
Uses 37-48mA more compared to a regular 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.

This flash cart will take up additional current compared to a regular cartridge due to the CPLD so you will see a decrease in battery life; this is standard for CPLD based flash carts.

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. If you don’t specify a ROM, it will be loaded with the LSDJ Demo.
