What is it?
DrSMS is a Sega Master System and Game
Gear Emulator. Basically it will allow you to play Sega Master System and Sega
Game Gear Games on your Gameboy Advance. Of course in order to run DrSMS on a
GBA you need a GBA flash cartridge, these can be bought from a number of places.
I won't bother supplying any links to websites that sell flash cartridges, just
go to www.google.com and search for "GBA FLASH CARTRIDGE".
could however run DrSMS on a GBA emulator on your PC. But running an emulator,
in a emulator is a bit pointless. But it does allow you to test DrSMS without
having to flash your cartridge which can be time consuming if you adding a lot
of games. I recommend Visual Boy Advance, it is brilliant.
How to use the DrSMS injector program
Run the program Drsmsver6.exe that is included with this readme file.
first need to add sms/gg games, this can be done in two ways. You can either drag
sms/gg roms on to the game list box directly from windows explorer or you can
use the "ADD" button. When you click on the "ADD" button it
will display a file browser, just browse to where your sms/gg games are stored
and then select which games you want. To multi-select simply hold down the CTRL
key while selecting with the left mouse button. When all of the games you want
have been selected click on the "OPEN" button. All of the games that
you selected will now be in the game list. You can only add rom images with .sms
or .gg file extensions. Compressed files (zip) are not supported so you will need
to extract the rom images from the zip files before you can add them to DrSMS.
remove games from this list, you can either remove them all by using the "CLEAR"
button or remove certain games by selecting them from the list using the left
mouse button and then using the "DELETE" button.
When you have
all of the games you want to play in the list, you need to specify the name of
the GBA rom you want to create. The GBA rom is what will be flashed to your GBA
flash cart. You can either type in the filename or use the "BROWSE"
When you have entered the name of the GBA rom to create, click on
the "CREATE GBA ROM" button. The program will now start to generate
the GBA ROM file for you. When it has finished a message will be displayed. Now
take the GBA rom and flash it to you GBA flash cartridge or run the GBA rom on
a GBA emulator.
How to use the DrSMS emulator
When you run DrSMS on your GBA
or GBA emulator you will be presented with a list of games that you have selected.
Unless you have only selected 1 games, in this case DrSMS will skip the game selection
screen and just start that game.
Use the UP and DOWN keys to select which
game you want to play. When the game you want is highlighted press "A"
button to load it.
In Game controls
Well it should
operate as a Master System would. All the controls on the GBA should be the same
as the SMS, i.e.
GBA SMS GG
--- --- --
B 1 1
A 2 2
DOWN DOWN DOWN
LEFT LEFT LEFT
RIGHT RIGHT RIGHT
SELECT ---------------> This start the DrSMS menu
Scrolls screen UP in unscaled screen mode
L ---------------> Scrolls screen
DOWN in unscaled screen mode
DrSMS Menu System
By pressing SELECT the DrSMS menu is displayed. The menu you allows you to change
emulation settings, save, load and delete "save games" and also to start
To exit this menu press B
select a menu option press A
RETURN TO GAME ---- Exits the menu
NEW GAME ---- Starts the Game selection menu
VIDEO MENU ---- Start the video
SAVE MENU ---- Starts the SAVE "save game" menu
LOAD MENU ---- Starts the LOAD "Save game" menu
DELETE MENU ----
Starts the DELETE "save game" menu
COUNTRY MODE ---- Allows you
to change the Nat ionisation
of the SMS/GG drsms is emulating
change this you will have to restart
you game to see any difference as most
only check this once at the start
THROTTLE ---- This allows you
to speed up the emulation
When throttle is ON, DrSMS will run at the same
speed as a SMS/GG
When throttle is OFF, DrSMS will run as fast
as it can.
Try it on Ninja Gaiden (GG) :)
To exit this
menu press B
To select a menu option press A
DISPLAY TIMING ---- Allows
you to select PAL or NTSC emulation timing
PAL = UK TV timing
NTSC = US
I'm not going to try and explain the details on
all you need to know is
NTSC = faster than = PAL
HACK = faster than =
Some games will only operate on the right display timing
the Future 3 for example will only operate in PAL mode
James Pond 2 - Codename
Robocod (UE) [!] will only do parallax
scrolling in PAL mode.
If you change
the display timing, I recommend restarting the
game to really see the difference.
SCALE MODE -----Because the GBA screen is smaller than the SMS screen
allows you to scale the screen to fit
In unscaled mode you can use the R and
L GBA buttons to
scroll the screen. If you are playing a GG game this menu
option will do nothing.
GG MASK -----Because the GG has a lower resolution
than the SMS but
still uses the same visual display processor (vdp) you
can sometimes switch the GG mask to reveal the game in
all of its full screen
glory. It doesn't work on all
games, but try it on the Sonic 1 for the GG
GAMMA -----Changes the brightness of the screen
SMS BLK REG -----Allows
you to turn off the sms "screen on" function
In previous version
of DrSMS, this option used to cause
flickering on the screen. I have hopefully
now fixed this
problem but I have left this option in here just in case.
SPRITE MODE -----Okay most SMS/GG games just use a sprite once per frame
are quite happy with that, some games on the other hand
are just greedy little
bitches. They try and use the same
sprite on more than 1 occasion during a
frame. This really
fucks with my sprite routines, so I have created a "buffered
sprite" mode to remedy this. So if your playing a game and
you find you
can't see some/all of the sprites just change
to the "buffered sprite"
mode and you should be alright. Its
not slower or anything like that it does
have sprite priority
issues that's why I have not made it the default mode.
This menu allows you to save your game.
Press B to
exit this menu
To create a new save, just highlight
"NEW SAVE" and the press the A button. DrSMS will then take the current
state of the emulator, compress it and then store it on the SRAM memory on your
flash cart. This means you can switch off you GBA, switch it on again and your
saves will still be there...unless you have an XGAY cart :O ( sorry private joke
). When DrSMS has finished saving it will display the name of the game in the
Overwriting an existing save
Just select the game you want to over-write and then press A. The old save will
be removed and then the new save created. The new save will appear at the bottom
of the list.
This menu allows you to load a
Press B to exit this menu
Use the UP and DOWN buttons to highlight
the save you want to load then press A.
Allows you to delete your save games
Press B to exit this menu
UP and DOWN buttons to highlight the save you want to delete then press A.
