NeoGenesis Sega Genesis/Megadrive/32X/SegaCD/MegaCD Emulator for XBox v16
- New (and very excellent) skin by J-RED
- New game configuration option : Overclock M68000 CPU feature
- Prevents slowdown on games like Sonic when lots of sprites are on-screen
If you are a first-time NeoGenesis user, simply upload all the files to a directory
on your XBox and run the default.xbe file.
If you are a previous user of NeoGenesis, you need to first delete the
E:\\SAVES\\NEOGENESIS\\SKIN_SETTINGS.INI file. Then you need to completely
remove your existing EMUSKINS directory and replace it with the new one in
If you don't follow those instructions, you will get a very weird looking
display. If that happens, go to "Configuration" -> "Video/Skin Configuration" ->
"Select Skin" and select the default_neogenesis skin. Things should then
be back to normal.
Now there's yet another reason why NeoGenesis is even better than a real
Ever notice in lots of games like Sonic and Strider that sometimes things will
slow down when lots of sprites are on the screen? This happens on the real
hardware, too. Now there's a way to correct that problem.
Go to the game selection menu, highlight a game, and press X to bring up the
game configuration menu. There is a new option called "Overclock M68000".
If you turn it on, you should notice that there is no more slowdown.
You can also turn on/off this overclocking from within the game. While the
game is playing, press the right thumb stick to bring up the in-game menu.
Select "Configuration", "Configure Controllers", "Controller 1",
"Change Emulator Definitions" and assign one of the emu buttons to be
"Toggle CPU Speed". Now go to "Change Joypad Mappings", "Change Game Mappings"
and change the button mapping for "Toggle CPU Speed". Now you can use that
button mapping to turn the CPU Overclocking on/off in the game so you can
better see the effects.
Most games don't suffer from any slowdown, so the overclocking option is
off by default.
It also doesn't work well with 32x or SegaCD games. SegaCD games cannot even start
if the overclocking option is on at startup. You'll need to toggle it on/off from
within the game.
WARNING : It is possible to put the emulator into an undefined state when using
the CPU Overclocking on 32x and/or SegaCD games. The symptoms of this are
stuttering music and halted gameplay. If this happens, you'll need to restart
NeoGenesis. If you just use the overclocking on regular non-32x, non-segacd games,
everything should stay fine.
