okay let me try to sum up the most important stuff for the 5 most wanted formats:
LunarMagic / Super Mario World
file types - .bps .ips
Website
Using Lunar Magic to create custom rom hacks of Super Mario World. Lunar Magic is completely free and able to load the Super Mario World Rom File. Getting the SMW Rom itself is fairly easy... searching for "smwOrig.smc" on Google gives a lot of results.
Since uploading the Rom itself might not be completely legal, it is recommended to use the tool
FLIPS to create a patch file (.bps) and upload that. (patches are legal)
(Older patch-files uses .ips extension)
Everyone else can then use this patch file with the smw-rom to create the working and customized rom, which can be played on a snes-emulator like ZSNES or Snes9x or on real hardware if you have... things to make it work lol.
TrackMania Nations Forever
file types - .gbx
Galgox shared a lot of information about this
here!
I'll copypaste the most relevant information:
This is a free-to-play racing game that features a custom track builder. Tracks are stored as .
gbx files, which shall be the file format required. Any custom track you build is saved to a folder named "TrackMania" which is located in your documents directory. All your user data for the game is stored in there. For custom tracks, they are specifically stored in
TrackMania\Tracks\Challenges\My Challenges.
You can put any custom track you download and save it to
TrackMania\Tracks\Challenges and it'll be ready to play in solo mode.
Official Site!
It can be downloaded on
Steam or
here.
You need to create an account to play it though (or is there another way to get it working?)
Stepmania
file types - .zip
Stepmania is a rythm game, where you can create "maps" for a music track. It's basically a rythm game, where you have to press buttons along with the music or beat to get a good score. As already mentioned by other users, the submissions should be limited to BotB entries only. The game itself is also completely free. I wasnt able to get it working correctly though, so if any of the information here is invalid, feel free to correct me :x
But from what i understand, you need to create a folder for your song (which will be submitted later as zip) and put the mp3 in it together with .pngs of wallpapers that will be used in the game while you're playing the map and a .sm-textfile, which contains the actual map-information. Setting up the file is explained
here, though it didnt work for me, maybe i did something wrong *shrug*
After you set up a raw-file, you have to open the game and select the blank song. You can now create your own level for it.
Would be good to not put the mp3 into the zip for the final submit, since its already on BotB.
Line Rider
file types - .json
Line Rider is a website for creating "movies" of a little person on a sleigh, which is riding over lines synced to a music track. The creation of those maps is done completely on the
website. Choose an mp3-file from your computer and start drawing lines. You're able to save your course into a json file, which can be loaded by the website. The mp3 isnt saved obviously, so for OHBs it would be required to set one specific botb entry to use or to link the entry in the description, if you're uploading it to a major.
Since you cant really "play" the map by yourself after its finished but only watch it like a movie, i dont know if its really fitting for a Mappist format though... maybe its more of a Grafxicist format? hmmmmm
Minetest
file types - .zip
Website
As Flaminglog said
here, it's the open-source and free alternative of Minecraft. I tested it and it works good! Worlds are stored in different folders in the subdir
/worlds. Submitting this world folder as a .zip would be required. The file size for a new created world is around ~2MB zipped, could be more if you create a lot of stuff, idk. But 10mb should be enough i guess.. same goes for every other suggested format!
