Awesome find, Jim. Many of those I'd only seen via in-game cameos in Wario Ware and the GB Camera.
I found it while researching DS games & figured you'd appreciate it.
I enjoyed your latest video by the way. I'll likely get the Ouendan games someday. How long do you get to keep the demo after the download?
All freestanding downloads can be kept until you turn off the system, and you can theoretically go forever without turning off the system, as shutting the lid puts it in standby mode. I had that one in RAM for two days.
My favorite band isn't in there. I demand a re-do!
