Just picked this up this week and WHOOO BOY! What a blast! The recreation of classic 8-bit style is a fantasic parody and XSeed did a great job on this.
Highly recommended!
While I’m thinking about it, what about a classic 8-bit, retro developer contest? 16K games? Would love some old school games in a comp like that…shmups and side scroller fight games. Double Dragon!
There’s the Retro Remakes competition, although it’s not in Java.
Sounds like a great idea, we’ve had similar contests in the past like the mario remake contest. Draw up some simple rules, maybe provide a link to some graphic resources and possibly throw in some small prizes.

Count me in.
OOn the topic of awesome DS games, you should check out Custom Robo Arena. It’s really fun! ;D
Plus, we could battle on Wifi. ;D ;D
