Ghosts'n Goblins arcade emulator for Nintendo DS

GhostsNGoblinsDS V0.1.7

This is a Ghosts'n Goblins - Arcade emulator for the NDS. Crappy sound but you should still be able to enjoy the games though. =)

How to use

Depending on your flashcart you might have to DLDI patch the emulator. Create a folder named "acds" in either the root of your flash card or in the data folder. Now put gng.zip, gngc.zip into a folder where you have arcade roms.

When the emulator starts, you can either press L+R or tap on the screen to open up the menu (the emulator tries to load "Ghosts 'n Goblins" automagically on startup). Now you can use the cross or touchscreen to navigate the menus, A or double tap to select an option, B or the top of the screen to go back a step.

To select between the tabs use R & L or the touchscreen.
