In this routine, line 90 gives infinite bombs, shields, mines, bounce and seekers, line 100 gives infinite lives and line 110 gives immortality. Play the tape from the start.

Your Sinclair have introduced an error in this hack. I tried running it twice on a tzx cassette image of the original game cassette. In both instances, once the game had loaded, the tape counter became corrupted, and the game crashed so don't waste your time typing it in. Still, there is another way to get infinite lives so all is not lost. Go to redefine keys, and define your keys as YXES to get infinite lives, then choose your type of joystick / or keys you wish to play with.
