CrocoDS is the Amstrad emulator for the Nintendo DS. It is based on the great emulator PC-CPC from Ludovic Deplanque (demoniak). It should run on any Nintendo DS with flashcarts that are supported by DLDI.

Installation

Patch the .nds file with DLDI if needed.

Copy the homebrew file (the .nds file) from the computer to the flash card.

Copy either .dsk or .sna file in the root (or in the /ROMS/CPC/ directory) of your flash card.

User guide

Switch on your DS and you will see a menu with the name of the homebrew file you've just transfered. Select it to run.

To load a ROM, press Select to display the menu. Select the game and play.

Controls

D-Pad/A/B - Joystick, Keypad, Keyboard emulation

Stylus - Control the Amstrad keyboard

Select - Display the setup menu
