First steps

2019-01-07 — Idea for LE-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

• 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.
• After the game is loaded, the buffer is still kept in memory and can be used for custom mods with the LE-CODE.

2019-01-30 — ct-code ported

• As of January 30, all ct-code mods have been ported or rewritten to work with the LE-CODE.
• Most MKW-Fun mods have been ported as well.

2019-02-10 — test script

• Leseratte made a small script to patch LE-CODE support into an image so Wiimm and Leseratte were able to do a few online tests.

~2019-02-14 — WLECT development

• Leseratte made a few changes to the LE-CODE to make it compatible with Wiimms tools.
• Wiimm started developing WLECT (Wiimms LE-CODE tool) so that we no longer have to create distributions manually.
• At the same time, Wiimm implemented LE-CODE support in its distribution-generator.

2019-02-15

• Leseratte developed a hacky way for LE-CODE to add additional ~20 slots to the game without breaking online support.

2019-02-25 — even more track IDs

• The hack from above has been removed. Leseratte started development for actually supporting up to ~32000 tracks in online mode.
• Korean games should now work properly and not freeze on track load.

2019-03-06 — track ID support finished

• Both online gameplay and online live view now support up to ~32000 tracks.
• Track icons changed from RGB5A3 to CMPR to reduce size.
• LE-CODE artificially limits the number of tracks to 4096 (you'd run out of memory for cup icons at some point anyways).

2019-04-01 — first public test distribution

• Wiimm and Leseratte released a public test version of Wiimms Intermezzo built with the LE-CODE to do some online tests with more people.
• From now on, all new builds of Wiimms Intermezzo (released every Tuesday) will be built using the LE-CODE.

2019-05-18 — various preparations for MKW Fun

• During the last months Wiimm and Leseratte did some cleanup of the LE-CODE and the MKW Fun build system to prepare the first MKW-Fun distribution with the LE-CODE
• A "mushroom car" feature (for tracks like GCN Mushroom City) has been added to the LE-CODE (thanks to Kevin (KHacker35000vr) for the code for that)

2019-06-21 — release of Wiimms Mario Kart Fun 2019-06

• Wiimms Mario Kart Fun 2019-06, the first real CT distribution based on the LE-CODE has been released.
