Super Mario Bros X is a fanmade editor and engine for making your own Super Mario games, based on a myriad of elements from Super Mario Bros 1, 2, 3 and World, amongst other games. It's very easy to make your own levels and compile them into an overworld, using the many preset items or indeed customising your own.
I've been having fun with it for a while now, and I thought it would be cool if we could collaborate on a level pack, "Super STCO Bros" or something. Something better named, obv. Whatever.
Honest, it's easy - it's not easy-but-secretly-impossible. Doesn't require any rom hacking, and you can bosh out a level in, ooh, ten minutes. We could upload our stages to Mediafire or something, and I could combine them into a bigger overworld. You can make as many or as few levels as you want.
Rules, basically copied verbatim from another forum:
- Constructive criticism is pretty much universally accepted, but actually editing other people's levels is only okay if they say it is.
- Always put starting locations for both players. (In case of AWESOME, that's why.)
- The game can only support one checkpoint per level. If you have multiple checkpoints, the first one the player hits will be the only one that counts.
- Levels should be winnable without being forced to take a hit.
- Never trap the player. If a certain item or powerup is needed to progress in the level, make sure it either respawns, or the player can die if he lost it.
- Enemies should always work the way they did in the game they're originally from.
- All water and waterfalls should be swimmable.
- Invisible blocks should never be made necessary to finish the level.
- Never put Lakitu in any area where you can scroll the screen vertically. He'll try to compensate by approaching infinite speed.
- The SMB3 Lakitu enemy is ruthless and can only throw those green rolling spinies. Instead of using him, pick the NPC you want and make sure the "Lakitu" option on the left side of the NPC panel is set to "yes". This will create a much tamer SMW Lakitu who will throw that NPC regularly.
- Only five Yoshi coins, or none. Not one, or two, or six. Five, or none.
- Remember that if you put a powerup in a block, it will be a mushroom if Mario is small. Putting just mushrooms will mean they'll always be mushrooms no matter what. (Hammer and Tanooki suits will always be suits, as well.)
- If you have horizontal warp pipes, don't put the warp on center or it'll look weird when you enter. Always put the warp on the floor. Also, make sure any such pipes have a floor or block in front of them you can stand on, even if they're underwater.
New one, not really a level as such; rather a way for the player to pick one of three levels (or a fourth "secret" one). Destroy a block to choose a floor (left-to-right, floors 1-3; top, 4) and Mario will automatically trot off to it. Obviously you'll need to add in the warp-y things for those go-to levels.
Also, each floor has a different number of coins (top one has an extra life) that Mario collects on his way out, so it would make sense that the easiest level is the lowest floor with least coins and the hardest is the top floor with the life :B
Amusingly, on the previous level (elevator), I climbed up, hit the secret button, Mario automatically walked down and positioned himself halfway on the elevator, which rose up and crushed him against the ceiling.
