Wizards & Warriors (codes that alter the exit point of the blue door at stage 1):

Notes about these codes:
The blue door that is referred to is the blue door in stage 1, all other blue doors work as usual. It's hard to discern the stages of this game, I haven't counted the part when he falls down the tree in stage 1 as a seperate stage, neither have I counted the same part around the end of the game either.

I have tested the values 01-40 (hex), tried to find some rhime and reason behind the codes so it would be easier to find useful exit points (like the beginning of stage 2, 3, 4, etc.) but they seem too regular to be random and too random to be equation so I don't know what to make of it. In parantesis are the value for the code, I've tried to have them in order (from stages, grey, blue, red, pink door, bonus door/room, boss, and rescue the distressed damsel).

You always get to rescue Lucinda, the first distressed damsel, even if you defeat a different boss.

A couple of codes makes you loose the blue key you had, it is noted if so. All other codes lets you keep the key and everything you collected when you entered the blue door.

Negative values (80 hex and up to FF) seem to transform it into a grey door that can't be entered.
