MegaTraveller 1 Plus

MegaTraveller 1 Plus

MegaTraveller 1 Plus is a faithful remaster of MegaTraveller 1: The Zhodani Conspiracy (Paragon, 1990), written in Rust, with optional modern quality-of-life features. The default game has a modern panel layout and squad combat in turns. Classic 1990 combat is available in File > Options.

You need the files of your own copy of the 1990 game. Original game files are never included in this repository or the release zip.

Setup (Windows x64)

1. Unzip the release into a writable folder.
2. Start megatraveller.exe. On the first run it shows a drop box. Drop the folder of your original MegaTraveller 1 game on it (the folder that contains the file TRAV.COM), or press Choose folder... and pick that folder. The game checks the folder and copies the files it needs when you press Enter. Alternatively, copy the files into gamefiles\ beside the program yourself.
3. Follow the title menu to create a party, or choose Get Started Quick.

If the folder will not do, the screen says what is wrong with it and what to try. README.txt in the zip lists the 64 required files. Settings live in look.toml beside the executable.

Saving

• Save at a starport desk (Save), or with File > Save... on the ground map. There are eight positions; a used one asks before it is overwritten.
• F6 quick-saves and F9 quick-loads on the ground map (also File > Quick-save and Quick-load). The quick-save has its own position.
• The game also saves by itself when you enter a starport and after a landing, into three rotating autosave positions. autosave = "off" in look.toml turns that off.
• Load with File > Load..., with G > Restore, or with Continue Old Game on the title menu.
• The game cannot be saved in a fight or in flight; it says so.

Saves are in saves\ beside the executable. Saves of the DOS game are not compatible.

Mouse and keys

Mouse and keyboard both work, and you can mix them.

With the mouse: click a square of the map to walk there, and click a door to enter. Click a Traveller's portrait to select them; right-click it for the character record. In a fight, click an enemy to fire at it, or right-click a target for the list of its actions. Every menu row, list row and button drawn on the screen can be clicked. The click that brings the window to the front only focuses it; the next click acts.

Menu letters apply to the open menu. Press ? for help and Esc to close it.

The Plus window (F12, or the Plus menu) holds the Journal, the game log, the Characters page, the Map, Help and the bug report page.

Look

Look > Text offers IBM EGA 8x14 (default), IBM Plex Mono and VT323, plus Bold. Extra .ttf or .otf faces go in fonts\. Look also controls integer or fill scaling, 4:3 or square pixels, filters, screen effects, palette and background. Look settings are cosmetic: they never change the game.

View > Components docks a panel, opens it in its own window or hides it; View > Reset layout restores the default arrangement. File > Options holds Classic 1990 combat, Easier grenade range and Selective NPC autofire.

Testing scenarios

Open Testing scenarios with Ctrl+Shift+L to load a prepared setup, or run:

.\megatraveller.exe --scenario scenarios/m4b_medkit_in_pack.toml

Scenarios replace the current setup and require your original files. Release notes list known issues and how to report a problem.

Reporting a bug

1. In the game press F12, open the Bug tab, describe what happened and press Save report. The page then names the folder the report was saved to (acceptance\local\bugs\<date>-mt1 beside megatraveller.exe).
2. Zip that folder and attach it to a new issue at https://github.com/DrEvil-TitaniumHelix/MegaTraveller-Remaster/issues.
