# Pico10L

Pico10L is an implementation in MSX2 BASIC of classic Picross game.

he game consists in guessing the pixels to 1 of the image.



# Controls

- Cursor keys to move the cursor

- SPACE to invert state of a pixel

- 'x' to mark a pixel as 0

- '.' to mark a pixel with initial state

- ENTER to check if puzzle is risolved

- ESC to abandon game e go to next puzzle.

#Variables

PT: Points

ER: errors

SY:symbols

NR next row

NC: next col

CR contatori per riga

CC contatori per colonna

GC= character to guess

CP= char pointer

PA: power array

CB: char byte

CM: mappa del carattere

UM: mappa dell'utente

BB=grid base

- initialize GC (char to guess)

- read value of pixel from char memory to initialize user map
