Starlancer Mission Files Structure

End of Exploration

4D 01 2B 50 01

After many years, trying to decode "DTE" files had become more enjoyable than playing the game.

But now, thanks to AI, many of our friends have both given the game a new direction and made the "DTE" files (I've been struggling with for years) decoding possible.

I hope I've made at least a small contribution.

Thank you all.

Mission ending...

For start permission land loop

code:

3F 0A 28 01 16

value should be: 00 00 01

Each mission starts with a "failed" mark. In mission situation its turns success or partially success. I couldnt find this opcodes yet. So if we use land loop code it works with mission failed mark.

Landing depends to launched ship on start of mission.

If you start somewhere in space landing is not working game crashes.

Game coded this logic;

launch reliant >landing reliant.

if reliant destroyed> landing yamato

launch yamato> landing yamato

if yamato destroyed> landing yamato

PS:

torpedo trails are occurs when they launch from the torp carriers. if we put the torpedo on to any of place of space they not make trails when they star flying.

I made a basic mission to understand this situation:

20 trigger hex list number

01 destroy trigger

ce01 continue this offset when trigger triggered ce01=1ce*2=39c from 47bf7

We have now solved most of the triggers.

Success Unsuccess if/else system

Each mission is marked as successful partially success or unsuccessful in the mission. This is also recorded into the save game.

Probably

27 opcodes means read from memory

40 means write to memory

when ships dead in mission 1 opcode 40 writes 1 to memory then end of the mission 27 opcode read this value and decide success and unsuccess.

Mission 1 end section;

Triggers

Triggers are defined in starts at offset "3bbf7" in mission1.dte,

The green line is sabers destroy trigger. "01" means destroy trigger at the "trigger list" when we change it to "00"(shoot at trigger in trigger list) after we shoot to sabers in mission 1 trigger works and mission continues from offset "49003"
