Early 3D game that has you piloting your skills with a Tornado over treacherous landscapes.

To use a Kempston joystick you must first Merge in the Basic loader and then edit the following lines. Remember that there's some degradation in sound quality when using this method but 'you pays yer money and yer takes yer choice!'

20 DATA 55,62,255,221,33,0,64,17,156,191,
205,86,5,33,179,255,17,198,118,1,3,0,237,176,
33,182,255,17,210,132,1,5,0,237,176,201,0,0,0,
205,105,254,24,63
50 FOR N=65423 TO 65466
3000 RANDOMIZE USR 65423

To get infinite lives and time, Merge the program and stop the tape when you get the OK message. Now list the Basic loader and edit lines 20,50 and 3000 to match the lines shown below. Now type Run and start the tape from where you left off:

20 DATA 55,62,255,221,33,0,64,17,156,191,
205,86,5,62,0,50,190,136,50,15,132,201
50 FOR N=65423 TO 65444
3000 RANDOMIZE USR 65423

This hack has been tested by myself and does not work due to a printing error by Your Sinclair. After merging the BASIC loader of the game and adding lines 20, 50 and 3000 (as listed above) and RUNning the hack it crashes.
