Gameboy 1MB 128KB SRAM Flash Cart (Ultra low power, Perfect for LSDJ, Custom boot logo option)

$31.00

What do we mean when we say ultra low power? We mean it consumes the same power as a genuine cartridge and sometimes can be even lower power than them! It seems to shine when the Gameboy is under a high load. This is likely the lowest power 1MB flash cart available today! Designed and made in Australia.

This re-programmable Flash Cartridge is MBC5 (with some MBC1 support) which allows you to play most of the later released Gameboy/Gameboy Colour games including some of the Pokemon games (no RTC support), Zelda DX, LSDJ, etc and allows you to re-flash it with any flasher like GBxCart RW that supports the MX29F800C.

Excellent for LSDJ. Works with GB Studio v1.1.0+ with saving if you wish to develop your own game. Check this list of Gameboy games to see the ROM/RAM size and MBC type your game will have, you would be looking for MBC5 games but most MBC3 games should work and some MBC1 games may work.

Will be loaded with LSDJ Stable 9.2.L. Need to flash a game on this cart? Make sure to grab our GBxCart Flasher.

Comes in a clear reproduction GB cart shell (or a clear black if we run out of clear) and our label (separately for you to apply). Looking for other colour cart shells? Check our GB or GBC cart shell listing.

Description

This cart works on every Gameboy system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player. Games that require more than 1MB of ROM won’t work.

Comes in a generic Gameboy cartridge. Each unit is assembled in house and is tested on a Gameboy Advance.

Updated revision PCB v2.1 (requires quick soldering):
– Allows for a custom boot logo which takes 16KB, if your game takes up the full 1MB flash, the last 16KB bank will be overwritten. The custom boot logo works on the DMG, Pocket, GBC (05, 03) and GBA 40pin. The original boot logo will appear on these devices: GBA 32pin, GBA SP and Super Gameboy.
– Allows for 8KB RAM locking useful for MBC1 games like Donkey Kong Country 3.
– Allows for MBC1 ROM banking – requests for bank 0 gives bank 1, useful for games like the original Zelda – Link’s Awakening.

Specs
ROM: 1MB Flash
SRAM: 128KB battery backed with a CR2025 (should last 8 years or more) or CR2032 (should last 10 years or more)
MBC: MBC5 (with ROM banking range 0x2000 – 0x3000 to allow for some MBC3/1 games) (with MBC1 mode by bridging 2 pads).

Most MBC3 games should work.

Orders place after 25 Sep 2020:
MBC1 games that won’t work: Any that needs more than 8KB RAM or more than 1MB of ROM. Games must be flashed on MBC5 mode first.
Orders placed before 25 Sep 2020:
MBC1 games that won’t work: Any that needs more than 8KB RAM or 512KB of ROM.

The PCB finish is ENIG.

LSDJ users who use the custom boot logo should know it will fail the ROM check because it’s missing the last 16KB bank (which is all blank) so you will need to restore an existing save file to it first and it will work fine.
