As the name suggests, Dreamcastnoid is a stylised take on the old classic block-breaker Arkanoid but this version sees you take control of a rampant VMU whose sole purpose is to destroy PlayStation 2 consoles, controllers, boxes and...erm...wads of cash. It's a pretty fun little game and exactly the type of entry the DCJAM was intended for. There's a video below showing Dreamcastnoid in action, and you can download the game yourself here.
It comes as an mdf file which can be easily burnt to CD-R and played on a Dreamcast with Alcohol 120%, or alternatively you can chuck it at an emulator and play Dreamcastnoid that way. I spoke to Alfonso and he also told me there are some pretty cool cheats tucked away in Dreamcastnoid...but I'm not giving them away just yet! You can find more information about Dreamcastnoid over at Segasaturno. Enjoy!
