uoYabause is an Android version of Yabause, one of the few moderately functional Sega Saturn emulators that offers a decent compatibility list. This means, while you may not be able to play Saturn's complete catalog, you can enjoy a few signature games. On its official website you can find a complete list of compatibility. As usual uoYabause doesn't include any ROM. That said, you don't need to download or install any BIOS. To play a Saturn video game you just have to have its ISO on the device's memory. You can even have the ISOs stored on an external memory card. There aren't a ton of setup options in uoYabause, there are enough. You can change a few visual options to try to adapt the video quality to the strength of your device, and modify the controls (which may be a little uncomfortable by default). uoYabause is a powerful Sega Saturn emulator that, unlike many others, actually lets you play with this legendary SEGA console. You can enjoy playing Nights, Guardian Heroes, Daytona USA, and Die Hard Arcade among many other awesome games.
