I want a hacked version of Nintendo Badge Arcade that'll let me freeplay to my heart's content and will cycle through all the various badge boards over time. It's stuck on a default set of boards now, and Nintendo won't take my money even if I wanted to give it to them (and I already gave a lot to them because of Badge Arcade). So, like, just let me play the funny bunny UFO catcher.
Bonus points if it can have the original physics that allowed you to "wiggle" badges more easily. I could spend 20+ minutes while watching TV nudging badges, sometimes subpixel by subpixel, exploiting? the physics system to knock extra badges into the pit for free. You can still do it on some boards, but not as extensively, and they got in the habit of "pinning down" keystone badges that wouldn't move without significant pressure.
I'm still scraping by, even stuck with the default set and the single Animal Crossing training stage. Unfortunately some badges are almost entirely impossible without "steps", which requires I have two or more grabs. So I have to hope I get a lot of practice badges AND it grants the semi-RNG bonus credits to even have a shot at them.
