The EMS flasher is a simple command line flasher for the 64 Mbit EMS USB flash cart for Game Boy.

This software was written by Mike Ryan mikeryan@lacklustre.net and modified by Randy Thiemann uselinuxnow@gmail.com.

I added some filesize checks to ensure that you don't destroy your cartridge by accidentally writing a huge file.

BUILDING

$ make

On Mac OS X, prior to building you must install pkgconfig and libusb:

$ brew install pkgconfig
$ brew install libusb

RUNNING

The software has three major modes of operation:

• Write file to cart
• Read file from cart
• Read title of ROM on cart

Pass the --help flag to see all the options.

EXAMPLES

Rom

Write the ROM to the cart in bank 1.

$ ./ems-flasher --write rom.gb

Write the ROM to the cart in bank 2.

$ ./ems-flasher --bank 2 --write rom.gb

Read the ROM in bank 1 to file.

$ ./ems-flasher --read rom.gb

Read the ROM in bank 2 to file.

$ ./ems-flasher --bank 2 --read rom.gb

Save

Write the SAVE to the cart.

$ ./ems-flasher --write save.sav

Read the SAVE to file.

$ ./ems-flasher --read save.sav

Miscellaneous

Print out the titles of both roms.

$ ./ems-flasher --title

Note that you can force the target location by passing --rom or --save, otherwise the program will automatically read or write from sram if the filename ends in .sav.
