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 \at lacklustre.net> and others (see the AUTHORS file)
For more information, see the web site at: http://lacklustre.net/gb/ems/
To build ems-flasher pkg-config and libusb are needed. Additionally, OS X requires coreutils and gawk.
On OS X, install the prerequisites using:
brew install pkg-config libusb coreutils gawk
(thanks to hyarion for this info)
On Ubuntu/Debian you can install them by:
sudo apt-get install pkg-config libusb-1.0-0-dev
./config.sh --prefix=/usr
make
sudo make install
After running ./config.sh, make sure the installation path of the binary
(BINDIR), the menu ROMs (DATADIR) and the manual page (MANDIR) suit you. If
not, you must run the tool again by specifying the desired paths. Use the
--help option to get the list of all options. If ems-flasher is ran from the
build directory, it will use the menu ROMs located in the same directory, not
the one selected with config.sh so you can use the software without
installing it.
The software has four major modes of operation:
- write ROM(s) to cart
- read ROM from cart
- read title of ROM on cart
- delete ROMs
To write use --write, to read use --read, and to get the title listing use --title. You can specify the page (1 or 2) with --bank PAGENB. If no page is specified, page 1 is assumed.
Write mode will write the ROM files specified on the command line to the selected page to the cart. Read mode will read the entirety of the page (32 megabits / 4 megabytes) into the ROM file specified. Specifying multiple ROMs will cause all of the ROMs to be written to the specified bank along with a menu to choose from them. Some ROMs support enhancements of the Super Game Boy or the Game Boy Color or both. For maximum compatibility, you shouldn't mix ROMs with different enhancements support on the same page. However, if you don't intend to use a Super Game Boy or a Game Boy Color, you can mix ROMs that support, resp., SGB or CGB enhancements with others that don't with the --force option. This option is not necessary if the page already contains mixed ROMs.
Title mode does not require a file argument, and will print the ROM title listing to stdout.
The --delete command will delete the ROMs whose bank numbers are specified in parmeters. The --format command will delete all the ROMs located on the chosen page.
Additionally, all modes take a --verbose flag for giving more output. You can also adjust the block size, but it is recommended you leave this to the default of 4096 bytes for writing and 32 bytes for reading (used by the Windows software).
For a full list of options, run the command with the --help flag.
The MENUDIR environment variable may used to override the location of the menu
ROMs selected by config.sh.
# write the ROM to the cart
./ems-flasher --write totally_legit_rom.gb
# write several ROMs to the cart
./ems-flash --write copyright.gb infringement.gb
# saves the contents of the cart into the file; print some extra info
./ems-flasher --verbose --read not_warez.gb
# print out the title
./ems-flasher --title
In this version, the --read command dumps an entire page. It is not possible to dump a particular ROM.
Preferably use the bug tracker found at the web site (at the top of this doc) to report any bugs.
