== What is the 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]].
  
−
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.  
+
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.
  
−
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.
+
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].
  
−
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]).  
+
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.
  
−
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 be able to use the LE-CODE in [[Wiimms Mario Kart Fun 2019-06]] which will be released this month. 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 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]
+
== 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
+
{| class="textbox grid sortable alt"
−
* [[Leseratte]] had the idea to consolidate all existing MKW-Fun and ct-code mods into one new structured system.
+
|+ CT-CODE Features
−
* 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).
+
! Feature
−
* 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).
+
! Information
 +
|-
 +
| More Racing Tracks

; 2019-01-11 — StaticR buffer
+
=== Bugfixes ===
−
* 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.
+
{| class="textbox grid sortable alt"
−
* After the game is loaded, the buffer is still kept in memory and can be used for custom mods with the LE-CODE.

Leseratte developed the LE-CODE as a complete build system for all modifications Wiimm and Leseratte are doing to [[Wiimms_Mario_Kart_Fun|Wiimms MKW-Fun distributions]]. It includes nearly all features of the old ct-code (even though all of them have either been rewritten (C or ASM) or heavily modified to fix quite a few bugs), and it includes all of the features in the MKW-Fun distributions.  
+
* Added Hidden Position Tracker.
−
 
+
* Fixed cutscene for Team Races.

+
* Added [[Item Cheat]].
−
*** 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

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]] 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.

* Increased the track limit to 8,192.

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.
