Super Mario Bros. X

Super Mario Brothers X (commonly known as "SMBX", as well as "Legacy Engine") is a Mario fan game engine, written by Andrew "Redigit" Spinks in 2009. The game is written on Visual Basic 6 (VB6). Project development was stopped in 2011, and SMBX 1.3 is the last official version.

History
In the year 2009, Andrew 'Redigit' Spinks began to work on the game Super Mario Bros. X. Gradually the game gathered a following among the fans of the Super Mario game series.

It is viewed as one of the all time best fan games about Mario. It features game elements from classic games such as Super Mario Bros., Super Mario Bros. 2, Super Mario Bros. 3, Super Mario World, The Legend of Zelda, etc. The built-in level editor allows you to not only edit levels alongside with an engine to debug them in real time, but also allows the player to create full-fledged episodes with a plot!

Unfortunately, in April of 2011, Redigit received a call from the lawyers of Nintendo, who demanded the removal of SMBX and the halt of development. After some time, the supermariobrothers.org domain was also taken over by Nintendo. And thus, a remarkable project was killed.

But even so, it is still being played. A lot of "episodes" are being created as of now, and the game is still in demand. Currently the game overloads the processor to 100% even when the user is not in action.

There were attempts to revive the project, but they failed.

The main mistake – the game was published under the untwisted brand.

And Redigit was making money off SMBX via the distribution of ads in its installer, on forums and the website. I.e. he infringed on the brand. Therefore, Nintendo decided to send Redigit a cease-and-desist, which forced him to abandon SMBX.

SMBX now
As of now, SMBX is still in demand, and constantly receives new levels, graphics and even episodes. Because of this high demand, LunaDLL has started to be developed.

About the game
Super Mario Brothers X is a community driven sandbox game where anyone can create their own episodes with an individual plot. Episodes made for this game aren't in any way connected to the official Nintendo series or Mario cannon, but some episodes are an attempt to create remakes of original games or unofficial continuations of official games.

Graphics
Most of the graphics are rips from original Super Mario games or other games for the SNES (or in some cases the NES). Some people create recolors, restylings or even their own original pixel-art graphics, original characters, sceneries and a new atmosphere. The game has a 800 x 600 resolution. Most of the graphics are 2x-scaled pixel-arts (2x pixel). In some cases it is possible to have non-scaled graphics, but mixing them with regular 2px graphics is not recommended, in order to keep the style in a good state.

Music
Super Mario Bros. X uses music from the following Nintendo games:
 * Super Mario Bros. (the All-Stars version for the SNES, 1993)
 * Super Mario World (SNES, 1990-1992)
 * Super Metroid (SNES, 1994)
 * Zelda II: The Adventure of Link (NES, 1987-1988)
 * The Legend of Zelda: A Link to the Past (SNES 1991-1992)
 * Star Fox (SNES, 1993)
 * Super Mario 64 (Nintendo 64, 1996)
 * Super Smash Bros. Brawl (Nintendo Wii, 2008)
 * Super Mario Galaxy (Nintendo Wii, 2007)

Sound Effects
Super Mario Bros. X uses sound effects captured from the following Nintendo games:
 * Super Mario Bros. (the All-Stars)
 * Super Mario World
 * Super Metroid
 * The Legend of Zelda: a Link to the past

The Invasion
The episode got released with the very first version of Super Mario Bros. X by Redigit. The Invasion features Mario and Luigi trekking through many different worlds to defeat Bowser. Along the way, they travel through seven different worlds, a Mario staple at this point. At the end of each world, they either go through a castle to face a boss (which is always a certain number of Boom Boom's or Birdo's) or, alternatively, they go through an “invasion” level, a difficult airship stage, ending once again, with a boss battle.

There is no story introduced in this episode. The Invasion 2 (read below) however improved greatly on many things in it, and this includes the addition of a story line.

The episode features 54 levels. The episode was included with SMBX by default until SMBX 1.2 got released, where it was replaced by The Invasion 2. The Invasion comes pre-packaged with SMBX 1.1.

The Invasion 2
This is a remake of The Invasion. It was made to include new features from the later versions of Super Mario Bros. X. The remake also features a clear story, something the original lacks. Aside from that, the overall gameplay is the same.

Plot
Bowser has, yet again, invaded the Mushroom Kingdom. But this time, he has the help of villains "from other realities" (i.e., different games). Unlike many other Mario games however, Bowser has not kidnapped a princess. Instead, Mario (or whoever the player chooses to play as) has to stop his invasion.

Gameplay
The episode contains many new features, gimmicks and extras. Bowser is still the main antagonist, but this time around he has the help of new villains, such as King Wart, Ludwig von Koopa, False Bowser, Mother Brain, Larry Koopa and Mouser.

Originally released with Super Mario Bros. X 1.2, the episode has constantly been updated in small ways with each new version released. It is the default episode that comes packaged with Super Mario Bros. X, and it is the main story of Super Mario Bros. X itself.

The Princess Cliche
The second episode released alongside with Super Mario Bros. X 1.1.0 Beta 1.

Plot
The episode revolves around Princess Peach getting kidnapped by Bowser after baking Mario a cake, which is an obvious reference to Super Mario 64.

The Princess Cliche features 14 stars spread around three worlds. This episode was available on the main page prior to Super Mario Bros. X 1.2's release. Afterward, it was replaced by its sequel, the Princess Cliche 2 (read below). Both are included with SMBX 1.1 (which can be found here).

Download

The Princess Cliche 2
Not so much a sequel to the Princess Cliche as it is a remake. The main premise is the same, but the levels have some minor extra features from the later versions of Super Mario Bros. X. Changes to levels are less prominent as opposed to in Invasion 2, as they have remain the same for the most part.

The main changes, includes the use of music from Super Mario RPG, a much tougher final fight, and a slight change to the game's ending.

When released, it replaced the original Princess Cliche on the main page. This episode is included with SMBX 1.1.

The Great Castle Adventure
The third episode that got released, but wasn't made by the game's creator Redigit, but by a level designing team led by one of the forum users, Zephyr.

Gameplay
The episode involves Mario and Luigi wandering through Bowser's castle to gather stars and ultimately destroy Bowser once and for all. The episode features 40 stars spread across approximately 40 levels, and ends with a battle against Bowser. The game is included with SMBX 1.1.

The New Great Castle Adventure
Made by KrazyKoopa, his brother Zephyr, Chad, and Valtteri. This episode is a remake of The Great Castle Adventure. It was released in August 2014. It contains 100 stars scattered across Bowser's castle, 35 more than the original episode had.

Announcement forum post

Return to Yoshi's Island
Made by Zephyr, the same man who created the Great Castle Adventure, this episode has the most levels out of any other, with a total count of around 90 levels. The episode has Mario and Luigi venturing through Yoshi's Island to save Princess Peach from Bowser and Wart. This was made to accommodate Super Mario Bros. X version 1.3, but because it was assumed to never be released, the episode was released in an unfinished state, with a few missing bosses. These include the Koopalings, which were supposed to be introduced in the aforementioned version.

Gameplay
The game engine uses Super Mario Bros. 3-like physics. The main game is accessed by starting up SMBX and pressing the button "Start Game" in the bottom left corner. This opens a loading screen displaying a legal disclaimer and asking the player to show support to Nintendo by purchasing a Wii (or a WiiU in version 1.3.0.1). When the game has finished loading, the start screen is presented with a level being played by AI controlled characters and a menu with various choices.

Main menu options

 * 1 Player Game - This option allows the user to play alone. When selected, the player can choose from a list of episodes that are installed in the user's "worlds" folder. After the player has selected a character on the next screen, the game will begin.
 * 2 Player Game - This option allows the user and a friend to play together. When selected, the player can choose from a list of episodes that are installed in the user's "worlds" folder. After the user and their partner have selected a character on the next screen, a two player game will begin.
 * Battle Game - This option is a two player only game mode, where the user and their friend can play together and battle on a list of battle levels located in their battle folder. After the user and their partner have selected a character, on the next screen, a battle will begin. There is no online function for this option.
 * Options - This option allows the manipulation of player controls, full screen, and allows the user to view the credits that play at the end of an episode. Player controls carry over to the level editor when testing levels as well.
 * Exit - This option closes the game.

Game Engine
SMBX uses it's own game engine written in the Visual Basic 6 language. SMBX is usually being used as an engine for Mario-like games such as fan-games about Mario or even independent game series like the A2XT Series by Talkhaus which includes the following games: ASMBXT, A2MBXT. Those games don't have much in common with the Mario series and most of music and sounds are replaced by original content.

Because development of SMBX was stopped, nobody can continue the official line of game engine development. Therefore in the Talkhaus Team, a special hacking extension (LunaDLL) was developed, which provides the ability to use a built-in SMBX API for scripts creation. Later Wohlstand started his researching campaign and created SMBX64 Standard which specifies technical metrics, file I/O interface, internal limits and some API features. The main purpose of this research work and of the SMBX64 Standard is a detail compatibility layer for a provision of the ability to read, write or modify SMBX Specific internal data and external content. After research has been finished, Wohlstand began with the development of PGE Editor which is the first part of the PGE Project - alternate implementation of SMBX Engine which is going to be a successor to the original SMBX.

Internal Editor
SMBX has an internal level and world map editor which gives you the ability to create your own levels and episodes.

The editor has a single-document interface: You have one sub-window which has a viewport where you can see your level or world map. All toolboxes are available at the bottom of the editor main window.

Level Editor
The level editor starts by default when you launch SMBX in the editor mode.

Each level has 21 slots for your sections. You can switch between sections if you open the "Level Settings" toolbox. In them you can also resize the section (you can set position for each boundary of the current section (top, bottom, left, right)), place a player start point. Set up music and the background of the section, set up the mode of the section (connect sides of section, enable globally 'underwater mode', enable 'off screen exit', disable able walk to left). To scroll on the map use the arrow keys and you can scroll fast by using the Shift key.

World Editor
The world editor let's you create your own world maps and allows you to change the episodes properties. To switch to the 'world map editor', open the "Mode" menu and select "World editor" menuitem.

Debugger


Debugger in SMBX 1.3/1.3.0.1. allows you to:


 * See how many Blocks, NPCs, BGOs and Warps are placed in a level
 * See their limits (some of them aren't correct, though)
 * See your current mouse position/coordinates on the level map
 * Swap blocks by typing their IDs
 * See Framerate speed
 * See how many elements are placed in the level, like power-ups, items, etc.

The "Blocks Sorted" button in the Debugger box of SMBX can be used if you want to make mess up NPC collisions, so that they fall through blocks. The button will be activated when you place some blocks in the level.

"Block sorting" means the internal sorting of list which has all placed blocks in the current level. All blocks should be sorted with X and Y coordinates. SMBX is using this internal collision detection algorithm with NPCs, which are trying to find a nearest block to check collisions with it. If the block array won't be sorted, NPCs will fall down or walk through some blocks. But the player will collide with those blocks, so he won't fall through them.

If you want to make this effect in your level, follow these steps:

1) Make a level, place blocks in the level, place some other blocks far away from the blocks you already placed (for example in Section 2) in the level, save and play-test the level.

2) After play-testing, open the level file in Notepad, and change block's positions (numbers).

3) When you're done, open the level again and test the level. SMBX will ask you if you want to save the level, when it will do that, always press No or else your notepad changes will be lost.

Note: If you will place some block in the level while play-testing the level, you will be able to press that "Blocks Sorted" button in the Debugger box, which will return things back to normal if pressed.

There is no Debugger box for World Map mode, maybe it was planned to appear in future updates of SMBX. However, in World Map mode you can see your current mouse position below, which is useful to make World Map warps or warps between level and world map.

SMBX 1.4 and the future of SMBX
SMBX 1.4 - was a most known for being a fake around YouTube. It would be the next version right after 1.3, but because SMBX development was stopped, nobody can continue the original project and thus resulting in there not being a "version 1.4". However, SMBX has successors which are will take SMBX's foundation and will continue progress:
 * PGE Project - is a project of the alternate implementation of an SMBX-like game engine which is fully compatible with it. You can play, create and edit levels or episodes which were made in SMBX as-is without porting of stuff. PGE uses configuration package system to offer you the ability to use independent itemsets to be able to create non-SMBX games from scratch. SMBX64 - the technical standard which defines compatibility layer with SMBX. To have working SMBX levels and episodes without glitches and content misses, you must use SMBX64-Standardized configuration packages for PGE.
 * VSMBX - a project by AeroMatter (aka GhostHawk) coded in VisualBasic.NET. The editor is similar to the original editor but is in fact not compatible with SMBX (it can't open SMBX's levels). Since 4 August 2016, AeroMatter announced discontinuing of the project.
 * SMBX-38A - a Chinese SMBX Engine implementation by 5438A38A, unofficial SMBX continuation by Chinese guy 5438A38A who did reverse engining of SMBX 1.3 and implemented some new features to it. Before recent time it was known as a fake. On September 13, 2015, by Snoopy Tour was made a post with a link to Baidu where Unofficial SMBX 1.4.1 was published, but people are not beloved him. Kevsoft tried to find a download link and finally found it, downloaded recent build from Baidu Pan and tried to test it on Windows 7 x64, but failed. When, he sent this build to Wohlstand, he found a way to run it in Windows XP using virtual box . Later Wohlstand contacted the original author and cooperated with him.
 * SMBX2 - is a big project founded by Horikawa Otane in december 2015 with basing on LunaLua library and implementing a wide set of lua scripts are implementing new power-ups, NPC, blocks, and lot of new gameplay features and bugfixes. Has a new launcher and uses the PGE Dev-Kit for it's powerful level and world map Editor.

Known bugs

 * If you use a decimal value in the npc-*.txt files, on some computers (from country where decimals standard uses comma [2,5 instead of 2.5]) SMBX will crash with the error "Runtime error 13: Type Mismatch".
 * Using empty strings with space characters will cause SMBX to crash.
 * If you customize scenery with ID from 32 to 65, SMBX will crash if you try to save the world map.
 * Peach's sprite has a wrong GFX offset settings of vine-climbing frames: Hitbox aligned to left-top corner of GFX.
 * When you place vines inside the SMBX editor, more vines will be placed under the original one due to the SMBX editor not checking if there already is a vine.
 * Using quotes '"' in the string values will damage level files (next attempt to load same file will cause SMBX to crash). But you're able to fix them in a text editor with manual removing of junk quotes from fields where quote characters are used.
 * Debugger box has wrong limit counters.
 * Blocks with a NPC inside will move to right with 0.001px offset when you hit it.
 * Skull raft will not stop correctly when it impacts with a wall. In result it is squeezed as an accordion.
 * Pokey the Cactus has a bug with his segments: When it walks on slopes, he will self collapse.
 * Spike Top can make invisible blocks visible when he tries to walk on it's bottom. When it walks over: It walks over them like on a pyramid.
 * When you try to grab any item while you're duck on the diggable sand, character will be frozen with digging animation
 * When the character standing in the Moving Layer, Climb with the Climbable BGOs will auto move by Moving Layer's Speed.
 * When you try to open too many levels in the Level Editor with a slow computer, SMBX will crash with "Runtime Error '-2137024822 (8007000e)': Out of Memory".
 * Climbable BGOs on invisible layer are still be climbable!

Gimmicks based on usage of bugs

 * If you spin jump into a Peach Block, you spin-jump as Peach!
 * Grab an item you are standing on, then spin jump to spin-grab.
 * Hold down when spin jumping to preform a Spin-Drill.
 * Hammer-suit/Bomb-suit are immune to fire.
 * Duck slide into a one-block hole, turn around, and unduck.
 * From (5), press down and alt. Run (as a tanooki statue) to go up.
 * Grabbing an item (from reserve) while performing glitch (5) will push you down.
 * If you jump at the right angle and unduck, you can push yourself through a 1-block wall made with upside down slopes.
 * If you go into a door and jump simultaneously, you can jump out of the other door.
 * If small, and you spin-jump with a spring, if you press up, let go to bounce higher.
 * Sometimes, when you spin-jump, if timed right, you can jump again.
 * With Peach, if you hover, if timed right, you can double or triple hover/jump.
 * If you have a fairy with Link, and you hit a spring with a fairy go ing down, when you tirn into Link, you will fly a little higger as if the spring kicks in.
 * If you hold up and use a spring board to go through a pipe, you can continue to spring through the pipe warp.
 * Ice that you make can ride water.
 * Rainbow shells ride water only when you ride them.
 * If riding a Shy Guy, or other NPC, you if you face a wall and jump, you gain no height, but if you face away from the wall, you fly through the wall. (Fix the first half)
 * If you stop time, you can climb a cliff with a Yoshi with only the alt. jump key.
 * With Peach, if you have a boot, you can time it so you can alt. Jump as soon as you touch it to get more hight, or more points from enemies or lives!
 * With Link, if you duck and stab a advanced powerup (either a Tanooki suite or Hammer Suit) while having only 1 heart at the time, you will clip into the ground.
