K80DS V0.3.9

This is a Konami 80's Arcade emulator for the NDS. It has bugs in the sprite rendering, no tile priority support & can't rotate vertical games. It supports the following games:

• Double Dribble
• Finalizer
• Green Beret / Rush'n Attack
• Iron Horse
• Jackal
• Jail Break
• Mr. Goemon
• Scooter Shooter
• Yie Ar Kung-Fu

How to use

1. Create a "acds" directory either in the root of your card or in the data directory (eg h:\data\acds). This is where settings and save files end up.
2. Now put your (zipped) games into a folder where you have (arcade) roms.
3. Depending on your flashcart you might have to DLDI patch the emulator.

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 Iron Horse 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.
