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|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. ==User guide== ===Menu=== '''File:''' * Load Game - Select a game to load. * Load State - Load a previously saved state of the currently running game. * Save State - Save a state of the currently running game. * Load Flash - Load flash ram for the currently running game. * Save Flash - Save flash ram for the currently running game. * Save Settings - Save the current settings. * Eject Game - Remove the game, can be used to enter bios settings. * Reset Console - Reset the console. * Quit Emulator - (If supported.) ===Options=== '''Controller:''' * A/B Autofire - Select to enable autofire on button A or B. * Swap A/B - Swap which NDS button is mapped to which arcade button.
