ROM Files and System Hardware
1. Certain ROM file formats will not work correctly on the EverDrive-MD. It is
highly recommended you use "romsets" that are generated by GoodGen
2. If you do not use the correct "romset" format then the game may not play
or may be buggy.
3. We offer no support if you use modified or hacked game ROM. Many of
these modified or hacked game ROMs will only run on emulators and not
original hardware.
4. Modified Genesis/Mega-drive systems or clone Genesis systems may or
may not work. In some cases the Genny3 Mode option may help in these
situations. There is no guarantee your EverDrive-MD hardware will work
on a modified or clone Genesis/Mega-drive system.
EverDrive-MD Menu
play game
Runs last flashed game.
select game
Copies new game to flash memory or runs a "module app".
• Hard Reset

enabled for best game compatibility, however may need to be disabled for
certain games and/or systems.

Hard Reset is enabled for Genesis/Mega-drive games. In the case
of Master System games the cart does a Hard Reset no matter
what this is set to.
o Off
Hard Reset is disabled for Genesis/Mega-drive games.
• SRAM Auto BackUp

(options continued)
• Genny3 Mode
The Genesis Model 3 does not have a clock signal on cartridge port.
When this mode is enabled the EverDrive-MD will use an internal clock for
the SD card. This mode will cause the SD card to run a little slower than
normal. This option should only be used if using a Genesis Model 3 and
may help with certain Genesis clone consoles.
o On
Genny3 Mode is enabled.
o Off
Genny3 mode is disabled.
• Region Free
If your version of the EverDrive-MD has a MEGAKEY (PCB 2.4 or later)
then it will be used for region free play. If your EverDrive-MD does not
have a MEGAKEY (PCB 2.3 or earlier) then the EverDrive-MD will attempt
to patch your game ROM for region free play.
o On
Region Free is enabled.
o Off
Region Free is disabled.
PLEASE NOTE: The MEGAKEY will NOT work if the
EverDrive-MD cart is connected via a 32X and also may not
work with other adapters such as the Game Genie. If this
situation is detected then the OS will attempt to patch the
game instead of using the MEGAKEY.
The EverDrive-MD supports Game Genie codes. These codes can be entered
manually or loaded from a text (*.txt) file. The text file should be no larger than
512bytes in size.
Codes are only applied during the game flashing process. Once the game is
flashed there is no way to disable them without re-flashing the game file.
Load from SD
Loads save data from SD card to SRAM.
Save to File
Writes save data from SRAM to existing SRAM data file on the SD card.
Save to New File
Writes save data from SRAM to a new SRAM data file on the SD card.

EverDrive-MD FAQs
Q: I get an error when I try to update my operating system (OS) and my
EverDrive-MD cart no longer shows the menu. How can I repair this?
A: Hold down A+B+C buttons on controller #1 and power the system on. The
reserve OS should start up.
Q: When I do a "Start Game" my Genesis/Mega-drive just shows a black
A: Disable the Hard Reset in Options menu.
Q: The game freezes, shows me an error message, or has just a black/red
screen. How do I fix this?
1. Game ROM file may not be in correct format.
2. Try to run your game file on an emulator. The emulator's region be
configured the same as the console's region (region shown in Tools ->
Device Info). If the game runs on the emulator then it will most likely run
on your Genesis/Mega-drive system.
3. Disable region patch.
4. Game Genie codes may cause a red screen. In this case you may need a
"master code" to disable the game from performing a self-check. It is
advised to learn how Game Genie codes work before using them.
(FAQS continued)
Q: How do I run a module on my Genesis/Mega-drive?
A: You need to select the module via the Select Game menu. The module will
then be loaded into the Genesis/Mega-drive RAM and executed. If you had a
game file already flashed into memory it will stay in flash memory.
Q: When trying to open the File Browser after selecting Select Game. I get
the error "can't open root dir". What does this mean?
A: It usually means you have not formatted the SD card using the Format SD tool
under the Toolbox menu.
Q: I see some weird glitches in File Browser. Is there something wrong with
my EverDrive-MD?
A: Most likely there is nothing wrong with your EverDrive-MD. First, ensure you
only have no more than 200 game files per directory (120 max on root or some
older OS versions). Second try formatting your SD card on your PC and then
format it again using the Format SD tool under the Toolbox menu.
Q: I am having some problems using Game Genie codes, what should I do?
A: It is highly suggested you learn how Game Genie codes work before using
them on your EverDrive-MD. The Game Genie is not a creation of KRIKzz so
support regarding them is limited.
Q: Can I downgrade the operating system (OS)?
A: Yes, but is it not recommended. Downgrading may cause the cart to no longer
operate correctly or at all.
(FAQS continued)
