Hey Chris, I downloaded the 2M version and at first I couldn't get it to work, but I checked the "bit swap" box in the Flashcard app and played it in my region-modded TG16 with the switch set to "Japan" and it started right up. I don't have the time to tinker with it, but maybe the issue I'm running into has to do with the card or the software or the gremlin in my console.
Regardless, I was able to get it to run and it's awesome! The rotating-looking graphics along the top are sweet, as is the hidden Keith Courage level.
The font is kind of hard to read, but some color combinations definitely make it easier. I can't wait for the next episode!
