Creating GFX based on Falcon Punch graphics

  • Edit Falcon Punch effect in vanilla using GE.
  • You can export Falcon Punch, add textures using Special textures, then reimport the model.

  • If the graphic ends up dark ingame, you should update the shading color in GE to white.

  • Open game in emulator, add breakpoint at 0x80101ED8 = dEFFalconPunchEffectDesc

  • Right at the start of the function, it loads the address to A0. It has the whole struct. Copy any offsets from there

Example: 

punch_anim_struct_TEST:
    dw  0x020F0000
    dw  Character.TEST_file_8_ptr
    dw  0x501C0000
    OS.copy_segment(0xA9AF8, 0x0008)
    dw  my_update_routine_ // Here, I'm overwriting the ProcRender function
    dw  0x00000040 // copied from the game's memory when playing ROM
    dw  0x000001A0 // copied from the game's memory when playing ROM
    dw  0x00000000 // copied from the game's memory when playing ROM
    dw  0x000001FC // copied from the game's memory when playing ROM
