The LE-CODE (short for Leseratte-Code) is a code extension for Mario Kart Wii which has been written by [[User:Leseratte|Leseratte]]. The name has been chosen by [[Wiimm]] in the style of the [[CT-CODE]], the name of the old Mario Kart Wii code extension by MrBean and Chadderz.  
+
== Overview ==
 +
'''LE-CODE''' (short for '''Leseratte-Code''') is a code extension of [[Mario Kart Wii]] initially written by [[Leseratte]]. After the initial phase, the code was jointly developed by [[Leseratte]] and [[Wiimm]]. It has been named after [[CT-CODE]], the name of the old code extension by [[MrBean35000vr]] and [[Chadderz]].  
  
−
Leseratte has started the development of the LE-CODE in January 2019. The build system is taken from the [[Wiimmfi/Update|Wiimmfi updater]], which means, it supports writing C source code instead of Assembly code for the game code modifications, and is designed to be loaded into the [[Filesystem/rel/StaticR.rel|StaticR.rel]] relocation buffer as soon as the StaticR.rel has been loaded and linked into memory, which has about 900 KB of usable space for mods.

Development started in January 2019, using the build system taken from the [[Wiimmfi/Update|Wiimmfi updater]]. This means that it supports writing C source code instead of Assembly code for its modifications, and is designed to be loaded into the [[StaticR.rel]] relocation buffer as soon as it has been loaded and linked into memory, which has about 900 KB of usable space for modifications.
  
−
Wiimm has adapted his [[Wiimms SZS Tools|SZS tools]] and wrote a new tool called "wlect" ([https://szs.wiimm.de/wlect/ Wiimms LE-CODE tool]).  
+
To use this code extension in other mods, [[Wiimm]] added support for management of LE-CODE and its additional features to [[Wiimms SZS Tools]], called Wiimms LE-CODE Tool. Additional documentation can be found [https://szs.wiimm.de/wlect here].
  
−
First test versions of the LE-CODE have been tested by Wiimm and Leseratte in February 2019, with the first version for a few more private testers being released on February 20th. The public will most likely be able to use the LE-CODE features as of Wiimms MKW Fun 2019-06. A system to use the LE-CODE in other custom distributions is planned, but not available yet. A source code release currently isn't planned.
+
The first few test versions were tested by [[Wiimm]] and [[Leseratte]] in February 2019, with the first version for a few more private testers being released on February 20th. LE-CODE could be used by the public after the release of [[Wiimms Mario Kart Fun 2019-06]], which happened in June 2019.
  
−
The LE-CODE can either be discussed on the talk page, or in this forum thread: [https://forum.wii-homebrew.com/index.php/Thread/59107-Mario-Kart-Wii-Mod-LE-CODE-by-Leseratte/ click]

=== History ===
+
== Features ==
 +
LE-CODE's features are based on a list of modifications that were included in the [[Wiimms Mario Kart Fun]] series. It includes nearly all features that [[CT-CODE]] has and all features of the former mentioned series.
  
−
; 2019-01-07 — Idea for LE-CODE
+
=== Features from CT-CODE ===
−
* [[Leseratte]] had the idea to consolidate all existing MKW-Fun and ct-code mods into one new structured system.
 
−
* He started looking for ways to extend the game code, possibly by placing it at the end of the heap (like MKW-Fun and CTGP 1.03 do).
 
−
* However, that would either require position-independant code (complicated), usage of the game's internal linker (even more complicated) or a fixed-length FST (would break if ISO is modified).
 
  
−
; 2019-01-11 — StaticR buffer
+
{| class="textbox grid sortable alt"
−
* The idea to use the heap has been discarded. Leseratte found a roughly 900 KB buffer within the StaticR.rel that is only used at game load.
+
|+ CT-CODE Features
−
* After the game is loaded, the buffer is still kept in memory and can be used for custom mods with the LE-CODE.

−
* Battle
 
−
** Battle mode actually works
 
−
** Battle mode has proper time limit online (3:00.000 instead of 0:30.000)
 
−
** Playing a battle no longer influences [https://tcrf.net/Mario_Kart_Wii#Online_Nametag_Drawdistance name tag view distance] in VS races played afterwards
 
−
* Demo screen
 
−
** Demo shows battle tracks as well
 
−
** Demo correctly switches modes in the proper order

*** Special feature for [[DS_Airship_Fortress_(Sniki)|DS Airship Fortress]] (usable in all other tracks as well): The {{obj-ref|woodbox}} object uses setting 8 for the drop height so it doesn't land on the wrong floor
 
−
*** Loading [[Template:Cannon_characteristics|cannon parameters]] from a [[LEX_(File_Format)|course.lex]] file inside a track so CT authors can define own cannon parameters.
 
−
*** Special feature for tracks like [[GCN Mushroom Bridge]] and [[GCN Mushroom City]]: The {{obj-ref|penguin_m}} object's settings can be used to make it behave like a mushroom car (spitting out a mushroom when hit) - thanks to [[User:KHacker35000vr|Kevin]] for the code to do that
 
−
*** The start line on the map can be freely placed anywhere (using a second KTPT entry with player index -1) and will (most likely) be rotated properly in mirror mode.
 
−
** Bugfixes
 
−
*** The icache is properly handled, this means that LE-CODE should properly work on Dolphin (but might require a version newer than about 5.0-9000 due to a Dolphin bug in older versions)
 
−
*** 4-player offline mode with Miis no longer crashes (LE-CODE no longer wastes memory with useless copies of unnecessarily large data structures like CT-CODE did)
 
−
*** After playing a Time Trial the minimap driver icons will be correctly resized instead of staying large
 
−
*** Playing a team GP no longer removes the Lightning from subsequent non-team GPs
 
−
*** The special random variants (new tracks, CTs, all tracks, Nintendo tracks) and the track variants now work offline as well
 
−
*** Playing GPs on custom cups no longer breaks the savegame
 
−
*** Fixed a bug that would cause the wrong trophy to be awarded in MKW-Fun due to cup reordering
 
−
*** <s>Fixed the recently discovered [[User:Leseratte#480p_graphics_fix|480p graphics glitch]] caused by a bug in the Nintendo SDK</s> ''due to the way this fix works it can't be embedded in the LE-CODE and has to be applied directly to the game''
 
−
* Menu
 
−
** Fixed a bug that could have caused freezes and/or graphical glitches in the menu under some circumstances
 
−
** In Time Trial mode, custom tracks are now hidden from the menu
 
−
** The Worldwide button on the online menu has been removed (instead of just being labeled "don't use")
 
−
** Scrolling through the cup list auto-updates the track list (also, as in previous versions, one can scroll in the bottom row as well)
 
−
** The algorithm that selected a track to be loaded when "???" is selected was slightly off and not every track had the exact same probability of winning the random lottery
 
−
* Not yet done, but likely to be added:
 
−
** TT ranking selection menu in the Mario Kart Channel is no longer broken

The new LE-CODE contains a few features for CT creators:
 
−
 
 
−
* [[ObjFlow.bin]] and GeoHitTable*.bin files can be loaded from the "Common" subfolder in an SZS track file
 
−
* [[Template:Cannon_characteristics|Cannon parameters]] can be loaded from a [[LEX_(File_Format)|course.lex]] file inside the SZS track file
 
−
* The {{obj-ref|woodbox}} object's setting S8 can be used to specify the height from which the box should drop
 
−
 
 
−
=== Detailed information ===
 
−
 
 
−
Certain files that would usually be loaded from the [[Common.szs]] can be loaded from a track file. Currently, the following files are supported:
 
−
 
 
−
* [[ObjFlow.bin]]
 
−
* [[GeoHitTableItem.bin]]
 
−
* [[GeoHitTableItemObj.bin]]
 
−
* [[GeoHitTableKart.bin]]
 
−
* [[GeoHitTableKartObj.bin]]
 
−
 
 
−
If you wish to include such customized files in your CT for Wiimms MKW Fun, you have to create a folder <tt>Common</tt> in your SZS track file and place the file(s) in there. For your own testing, you then have to replace them in the Common.szs as well, because the original, non-modded game doesn't load them from a track file.
 
−
 
 
−
As of v2.02a of [[Wiimms SZS Tools]] a simple command can extract all Common sub-folders to the correct place in only one step:
 
−
: '''wszst xcommon ./files/Race/Course/*.szs -qiod ./files/Race/Common/%N'''
 
−
 
 
−
In the future, we also plan to allow for track variants being loaded in different modes, for example, a different SZS for offline and online mode. The exact modes / distinctions we'll support aren't known yet, If you would like to create a CT that behaves differently in certain modes (offline/online, 1P/2P/3P/4P), and that track is likely to be included in MKW-Fun, let Wiimm and Leseratte know which different versions your track will have, and we will try to implement that.

== Wiimms SZS Tools ==
 
−
 
 
−
[[Wiimms SZS Tools]] support the LE-CODE extension like the [[CT-CODE]] extension before. The new tool ''wlect'' was created for LE-CODE and [[LEX]] support. If using tool ''wctct'' with option ''--lecode'', it switch internally to LE-CODE support and accepts track definition files in [[CT-CODE]] syntax. So you can use the same definition file for CT-CODE and for LE-CODE.

Overview

LE-CODE (short for Leseratte-Code) is a code extension of Mario Kart Wii initially written by Leseratte. After the initial phase, the code was jointly developed by Leseratte and Wiimm. It has been named after CT-CODE, the name of the old code extension by MrBean35000vr and Chadderz.

Development started in January 2019, using the build system taken from the Wiimmfi updater. This means that it supports writing C source code instead of Assembly code for its modifications, and is designed to be loaded into the StaticR.rel relocation buffer as soon as it has been loaded and linked into memory, which has about 900 KB of usable space for modifications.

To use this code extension in other mods, Wiimm added support for management of LE-CODE and its additional features to Wiimms SZS Tools, called Wiimms LE-CODE Tool. Additional documentation can be found here.

The first few test versions were tested by Wiimm and Leseratte in February 2019, with the first version for a few more private testers being released on February 20th. LE-CODE could be used by the public after the release of Wiimms Mario Kart Fun 2019-06, which happened in June 2019.
