The following offsets have been determined for Final Fantasy I only. All offsets are given in hexadecimal format. All currently described ASM routines are in Thumb mode. (Under Construction)

General Purpose Routines

Core Routines:

  • 000EFC-000F81 (000086) = Core division-related routines
  • 000F18 = General division routine. Given r0 = divident and r1 = divisor, checks for zero and calls software division
  • 000F2C = As above, but only returns remainder in r0
  • 000F68 = Divides r1 by r2; stores the product in [r0],[r0+8] and the remainder in [r0+4]


Game-Specific Routines:

  • 014E4C-014E6B (000020) = Uncompressed tile graphic size finder routine
  • 014E6C-0158E7 (000A7C) = Unknown (Short ASM routines)
  • 0158E8-0158FB (000014) = Chest State Determination Routine
  • 0158FC-01591B (000020) = Unknown ASM Routine (reads $02001DF0)

FF1 Stat and Animation Handling

  • 01591C-0159B3 (000098) = Total Attack Determination
  • 0159B4-015ACB (000118) = Total Defence Determination
  • 015ACC-015B8F (0000C4) = Total Evade Determination
  • 015B90-015C23 (000094) = Effective Max HP Determination
  • 015C24-015CB7 (000094) = Effective Max MP Determination
  • 015CB8-015D4B (000094) = Total Intellect Determination
  • 015D4C-015DDF (000094) = Total Agility Determination
  • 015DE0-015E73 (000094) = Total Stamina Determination
  • 015E74-015F07 (000094) = Total Strength Determination
  • 015F08-015F43 (00003C) = Current HP/MP Determination (And Possible Truncation)
  • 015F44-015F83 (000040) = Total Accuracy Determination
  • 01E2FC-01E8C3 (0005C8) = (ASM) Root Spell/Weapon Animation Handling
  • 01E8C4-01F12F (00086C) = (ASM) Unknown Routines
  • 01F130-01F1A3 (000074) = (ASM) Conditional Animation Effect Handling
  • 01F1A4-01F743 (0005A0) = (ASM) Animation Chunk Storage Routine
  • 01F744-02B2B3 (00BB70) = (ASM) Animation-related routines; exact function unknown
