GTA DYOM Editor
by Miran

Application for editing mission projects (*.dat)
used by DYOM (Design Your Own Mission) modification for GTA San Andreas.


The application mostly finished, but still in testing phase. Please make files backup before editing your important missions.
No documentation yet, so explore on your own.
I added tooltips in many places (hold the cursor still over elements), and context menus (right click).
Read changes log for more info.


Hotkeys:
Ctrl+S: quick save current mission project
Ctrl+R: reload current mission project from file. All unsaved changes will be lost.
These two are useful when working with windowed game and editor at the same time.
