Answer:

Used peek4 API for Read a half byte value from RAM. Add the print() (text). Go to left position (player).

You're reading the value of a certain pixel on the screen. Keep in mind that 4-bit nybble addresses are 8-bit byte addresses multiplied by 2.

For example, to read the low nybble of byte 0x0FF9D, use peek4(0x1FF3A). To read the high nybble, use peek4(0x1FF3B).
