Haha Banjo's Backpack is there. Does coolboyman comment here? I'm happy to have uploaded his utility onto this website. It was so bizarre that no one had bothered to, even though Banjo's Backpack has been out for at least a year, maybe two.
Yeah I've submitted three things so far, one of the others was dr. x's Feel editor for Ristar but someone already uploaded it. It is there in the Sega Genesis utilities section, but if you use the drop-down menu for "level editors" it doesn't show up. That's why I didn't see it and tried to upload it on my own. Just now, I edited the entry to change it from "game specific" to "level editor" hopefully the RHDN bot will change it.
Also I tried to upload an Ecco the Dolphin mod (there's no Ecco hacks here) from the Dark Caverns website that changed Ecco into an Orca, but upon reviewing the submission rules it's not allowed because it's a "simple sprite replacement" hack.
