redream

Redream is an emulator of SEGA's last console, the legendary Dreamcast, optimized to run on Android devices. With Redream, you can play some of the Dreamcast's most legendary titles on your Android device, including Jet Set Radio, Crazy Taxi, Space Channel 5, Shenmue, Power Stone, and Soul Calibur.

But one of redream's biggest advantages is it doesn't require BIOS or complex setup. Simply choose where on your device to store the ROMs. There are also a few different graphics options you can play with to see which looks best on your device, but it's not necessary to play ROMs.

The emulator controls can also be customized from the app's options menu. Although the default layout is quite comfortable, the controls can be changed by simply tapping and dragging the buttons wherever you want to customize the controls in a matter of seconds.

Overall, redream is a fantastic Dreamcast emulator, that works very well with many of the console's popular games. And it doesn't even require BIOS: simply select a ROM to run, and start playing! But be aware that, like most emulators, Redream doesn't come with ROMs.
