First build working for real hardware

Place folders contained in zip file in the root of your SD-Card.

Tested on New 3DS XL

• Expect crashes
• Missing keybindings
• Only a preview not seriously playable

Running on 3DS (emulator)

Only a showcase, far from stable. Place the data/ and cataclysm-dda/ folders in the root of your SD-card or inside Citras sdmc/ folder.
Launch the cataclysm-tiles.strip file with Citra, or try it on your 3DS.
