The following article is a ROM map for Final Fantasy I & II: Dawn of Souls.
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
