S8DS is more or less a port of SMSAdvance to the NDS. It emulates the Sega Master System and the Sega Game Gear.

Changes:

*Added option to turn off 3D display.
*Fixed color/saturation setting for SG/Coleco games.
*Fixed some bogus handling of the 3D display mode.
*Fixed “Perfect Sprites” mode, should now be used as default.
*Changed startup values for VDP regs 0,1 & 10, might break something.
*Changed sound renderer to be more correct.
*Removed PAL timing for GG.
