About
Thrust is a 1986 BBC Micro game by Jeremy C. Smith, published by Superior Software, in which the player pilots a spaceship using rotation and thrust across a two-dimensional landscape and caverns — gameplay heavily inspired by Atari's Gravitar. This is a disassembly and technical documentation of the original Thrust BBC Micro game, decrypting and annotating its 6502 assembly source, verified to reassemble correctly using the BeebAsm assembler.
Getting started
Assemble the documented source into a working BBC Micro disk image using the BeebAsm assembler.
History
The disassembly builds on prior notes and disassembly work credited to another contributor (jms2), using the BeebDis and BeebAsm tools created by others in the retrocomputing community.
