For various options (as shown in the REM statements), type in this Bleeploader based routine, RUN it and play your original Earthlight tape from the start.

Something Your Sinclair fail to mention. Their are two versions of Earthlight - one for the 48k Spectrum, the other is for the 128k Spectrum. This hack is for the 48k version of the game.

Another printing error by either Your Sinclair or Dennis Publishing. Line 104 fails to provide infinite fuel. If you have typed in this hack, delete this line, because it has no effect in providing you infinite fuel. As usual, I provide a link below where you may download this hack with the aforementioned fix.
