NeoDS the NeoGeo emulator for the Nintendo DS by Imgramb hasnt been updated for a while but the coder of the project posted this at pocketheaven:

The new version will have a new (faster) cpu core.
No release date I've made a lot of progress, but there is a lot of progress to be made. And real life is keeping me busy for now.

Awesome news for fans of the emulator.
