From GameBrew - a wiki dedicated to Video Game Homebrew.
DSonic is a little homebrew game similar to the minigame in Wario Ware.
Once the game starts off it asks you to press the touchscreen, then it will randomly place pictures of Sonic and Mario all over the screen.
You have to hit the Sonic pictures while they move around, avoiding Mario. It's a timed game and will give you a score when it's done.
- Sonic +1
- Eggman -3
- Rings +3
- Mario -6
Operate with Stylus.
The game runs on DeSmuME but the speed is 2x faster and the sound is not supported.
