This is a SNK Neogeo Pocket (Color) emulator for the Nintendo DS.

Features

Should play most games.
Can save flash ram.

Installation

Note: You will need a bios to be able to save in game.

DLDI patch the emulator for your flashcard.

Create a folder named ngpds in either the root of your flash card or in the data folder.

Then put game/bios files into a folder where you have (NGP) roms.

Max 768 games per folder, filenames must not be longer than 127 chars. You can use zip-files (as long as they use the deflate compression). Caution: Games that require SLOT-2 RAM can not be used with zip-files.

Since the DS/DS Lite only has 4MB of RAM you will need a SLOT-2/GBA cart with RAM on these devices to play games larger than 2MB.
