a 2d fighting game where you can script characters and design levels. the game's only limit is the size of your msg card.be sure to read the included read me!!
For me if you want to emulate the DS the best option is on Android, use DraStic and a controller that holds your phone... it's clunky but it works insanely well. The next best option in my opinion is using a New 3DS XL, not really emulation but hacked it works really well.
