Delta Touch

Delta Touch, formerly known as D-Touch and Doom Touch, is an application for Android by Beloko / Open Touch Gaming that bundles Chocolate Doom, GZDoom, Zandronum, Doom Retro and PrBoom+ together, offering a common and configurable touch screen interface. It also includes Freedoom to allow its users to have a game to play even if they do not transfer IWADs from their computer. It supports all games supported by its engines, though of course some games may not be supported on all engines. The GZDoom and PrBoom+ engines offer both software and hardware-accelerated rendering.
