*Disable sprites - Turn on/off sprite rendering.
 
Other Settings:
*VSync - Switch between speed modes, can also be toggled with L+START.
**On - Will wait for the next vsync if needed, best for most games.
**Force - Can help with graphics in some games, often slow.
**Off - Can speed up some games if they don't allready use all cpu time.
**Slowmo - Good for beating that extra fast game.
*FPS-Meter - Toggle fps meter.

*Change batteries - Change batteries in the NGP.
*Change sub battery - Change the clock battery in the NGP.
*Use BIOS - doesn't work yet.
*CPU speed - Set the CPU speed of the NeoGeo Pocket, this doesn't lock the cpu speed, the games can still change it.


Save Manager:
'''Machine:'''
*Save SRAM - Save the SRAM for the current game (it's automaticly loaded).
* Language - Select between Japanese and English.
*Manage savememory - Lets you erase SRAM (for now).

Others:
'''Settings:'''
*Sleep - Put the GBA into sleepmode (activated from this menu or from 5/10/30 minutes of inactivity).
* Speed - Switch between speed modes (Normal, 200%, Max, 50%).

* Autosave Settings - This will save settings when leaving menu if any changes are made.
* Autopause Game - Toggle if the game should pause when opening the menu.
* Overclock EWRAM - Changes the waitstates on EWRAM between 2 and 1, might damage your GBA and uses more power, around 10% speedgain. Use at your own risk.

Make sure your flashing software allocates 64kByte/512kbit SRAM for NGPAdvance.

===Advanced===
'''Other:'''
EWRAM speed:
* Sleep - Put the GBA into sleepmode. START+SELECT wakes up from sleep mode (activated from this menu or from 5/10/30 minutes of inactivity).
*This changes the waitstate on EWRAM between 2 and 1.
* Quit Emulator - Tries to reset the Flashcart and reboots the GBA.
*This can probably damage your GBA and definitly uses more power, around 10% speedgain.
*Use at your own risk.
 
[[PogoShell GBA|PogoShell]]:
*Copy ngpadvance.gba to the plugin folder (or compress it to mbz before you copy it).
*Rename it to ngpadvance.bin and add either one of the following line to the pogo.cfg file:
**<code>ngp 1 ngpadvance.bin 2</code>
**<code>ngp 1 ngpadvance.mbz 2</code>
