DraStic DS Emulator on Android is now free to download, will be taken down soon
Exophase, the developer of the DraStic Nintendo DS emulator, has made a statement regarding the future of the emulator. DraStic has been a popular closed-source DS emulator on Android that has been available for many years. However, following the fallout from both Yuzu and Citra emulator's situations, Exophase has decided to take DraStic off of the Google Play Store. According to them, DraStic was already going to be pulled from the Google Play Store, regardless of current events, but that things made the issue, "more urgent".
Before the app gets delisted, Exophase has made DraStic free to download, when it had previously cost $4.99 to buy. They plan on eventually releasing the source code for the emulator as well. You can grab DraStic DS Emulator from the Google Play Store here.
