So, I've made a couple of beatmaps a few years ago that were originally made for O2Jam (osu!mania but ancient) and I've successfully ported them over to osu!mania, they are playable-- I can play them just fine. I'd like to share some of them to mania players too, especially those who'd like to experience O2Jam nostalgia. But when I try to upload them, the game is saying that the beatmap isn't mine. I don't feel like putting about 4000++ notes of a song one by one again. Is there any way that I could submit them, aside, of course, from starting from scratch? I'd appreciate any input. Thank you!
