Rocket Man - Commented Disassembly

A fully commented disassembly of Rocket Man from Software Farm is now available
here allowing you to discover exactly how this classic pseudo hi-res game works.
And using this I have created a conversion of the game for the 48K Spectrum, which can be found
here.
The conversion uses the original code re-assembled 16K higher in memory so that it clears the Spectrum's display file. The code has been patched so that whenever the ZX81 display file gets updated its contents are rendered into an equivalent image in the Spectrum's display file. This approach allows the Spectrum to run Julian Chappell's actual code to achieve an experience near identical to the ZX81 original.
A video of the converted game can be found on
YouTube.
