The lower case letters: u, v, w, and k, are significant for player two. The level code contains 16 characters: ABCD EFGH IJKL MNPS. An increase of lives, keys, credits and weapons will be represented by an increase in the count of the front code characters: A --> B --> ... --> M --> N --> P --> S

Simultaneously, the count for the -YY- end code decrease: S --> P --> N --> M --> ... --> B --> A

The characters O, Q and R are counted, but not noted. This means, the step from -N- to -P- at "lives" position five must be completed in the end code by a count from -J- over a figured -I- to -H-. For the step leading from life six to seven, the code at position five changes from -P- to -S-. This means, the end code must be simultaneously changed from -H- over -G- and -F- to -E-. -G- and -F- are equivalent to the unnoted characters -Q- and -R-.

Restarting a level, a maximum of seven lives, five ammunition kits und fifteen keys, limited by the -S- code, will be generated. A scanner is not noted in the level code. Some variations at positions one and two for the tower level are possible, but it`s not funny to see your player wandering aroung outside the outer wall of the tower.

So, change position 10 and 11 to -SD-, leave position 16 unchanged and change position 15 by counting one possible character down.

If you want to get the two-player -SSSSS- code directly from the one-player -DCAAA- code, count down 85 characters at the -YY- end code.
