Chip tiny.png The following article is a RAM map for Arcana.

(Back to Main page)

The list corresponds to RAM variables used by the game engine. They are generally accessed by LDA and STA instructions.

Main Loop

  • $1049: Pointer to indirect function calls (JMP [$1049])
  • $1E10: Event pointer, used for reading most of the game's code (LDA [$10]) (long ptr)
  • $1E14: Event pointer stack, stores return addresses during function calls

Temporary Arrays

Typically these are accessed i.e. LDA $09C7,x where the x register is determined at runtime.

  • $0643-065B: Enemies in battle (Enemy ID + 18), set to FFFF when killed
  • $09A3-09BB: ??
  • $09C7-09DF: Miscellaneous return values (i.e. type of treasure contents, item/spell/enemy chosen)
  • $09EB-0A03: Current selection (Attacker ID, caster ID, whose turn is it etc)
  • $0A0F-0A27: Target (ID being attacked, treasure chest being opened)
  • $0B9F,x: Stores function results (0=failure)
  • $0CB3,x: Stores function results (0=failure)

Battle

  • $0A87-$0A8E: Current selected battle command (2 bytes per character)
    • #$0001: Main menu
    • #$0003: Items/Magic
    • #$0004: Cards
    • #$0005: Weapons
    • #$0008: Attack
  • $1121: Attacker
  • $1123: Target
  • $1127: Spell ID
  • $11C1: Battle state (00=not fighting/can move, 02=battle poses, )
  • $11C3: Status/Condition (a series of words in the order: Rooks, Spirit, Guest1, Guest2, Enemies 1-8)
    • Odd byte:
      • #$00: Satisfactory
      • #$01: Deceased
      • #$02: Not Here
      • #$03: Paralyzed
      • #$04: Petrified
      • #$05: Confused
      • #$06: Sleeping
