DraStic

So, I've been trying to play a couple yugioh games that I used to play when I was a kid but neither of them can be found when I hit load new game on drastic.
The games are Dark Duel Stories for the gameboy color and The Sacred Cards for gameboy advance. I'm using a Samsung Galaxy S5 if it helps.

If anyone can help that'd be great, and I sent an email to the email supplied on the google play store but haven't got a reply yet.

DraStic only plays Nintendo DS games. There are other emulators for Android that support Gameboy Color and Gameboy Advance, including many that are free.

There's a good list of emulators for Android here: https://www.reddit.com/r/EmulationOnAndroid/wiki/index
