More or less a port of SMSAdvance to the NDS now under the name of S8DS, as it's a SEGA 8-bit emulator for the DS.
The biggest difference from the GBA is probably that you don't have to use a builder to add roms, you can use zipped files directly and the screen doesn't have to be scaled to fit.

Changelog:
*Added R as FastForward.
*Fixed Bios handling on MD (Frogger proto GG2SMS works).
*Fixed "Border Off" for GG.
*Sprite collision is now "On" by default.
*Changed R as GG start to X as GG Start.
