Slot 2 Mapping Flat Code in $00000 - $07fff [1] and $1c000 - $1ffff

Game State

Fantasy Zone maintains a master "game state" variable in the low 4 bits of the byte at $c01f. The valid values are:

ValueState
$0Sega Mark III Logo Screen
$1Title Screen
$2Demo
$3Gameplay
$4Huge Creature Fight
$5Life Lost
$6Huge Creature Destroyed
$7O-Papa Destroyed
$8, $9 [2]Epilogue
$aPrologue

For some states, bit 7 of the same byte is used to distinguish a change of state (bit 7 reset) from a continuation of the current state (bit 7 set).
