Elite : Harmless

Elite : Harmless is a greatly enhanced version of the Commodore 64 port of the seminal space-trading-combat sim Elite, made possible by a full disassembly.

State Of The Project

The game is disassembled but documentation is on-going.
Some improvements have been implemented, see below. Help is wanted in these areas.

Improvements Implemented

• Multiplication routine upgraded to a faster version: I was able to free up 2 KB and insert some multiplication look-up tables which gives a general speed-up for 3D math

• Faster line-drawing code, provided by dyme

Planned Improvements

• Speed improvements
• "Quality of Life" improvements, making the game more accessible to new players and players who may never have played an 8-bit or C64 game before
• Feature enhancements
• See the complete list of issues

Getting Elite : Harmless

Due to legal concerns, Elite : Harmless binaries (i.e. disk images) are not made available, you will have to build the source code yourself using the instructions provided in INSTALL.md.
