You are decompiling an assembly in ARM7 of a Gameboy Advance game.

You know that this assembly:
```

```

Translates to this C code:
```
void Task_80583D4(void)
{
    Akatento *enemy = TASK_DATA(gCurTask);
    AnimCmdResult acmdRes = sub_80584A8(enemy);

    if (sub_8058518(enemy) == TRUE) {
        TaskDestroy(gCurTask);
        return;
    }

    if ((gStageData.unk4 != 1) && (gStageData.unk4 != 2) && (gStageData.unk4 != 4) && (acmdRes == ACMD_RESULT__ENDED)) {
        Sprite *s = &enemy->s;

        if (s->frameFlags & SPRITE_FLAG_MASK_X_FLIP) {
            s->frameFlags &= ~SPRITE_FLAG_MASK_X_FLIP;
        } else {
            s->frameFlags |= SPRITE_FLAG_MASK_X_FLIP;
        }

        s->anim = gUnknown_080D1E20[0].anim;
        s->variant = gUnknown_080D1E20[0].variant;

        gCurTask->main = Task_Akatento;
    }
}
```

Use the following structure for the `enemy` variable in the new code:
```
typedef struct {
    /* 0x00 */ MapEntity *me;
    /* 0x04 */ u8 unk4;
    /* 0x05 */ u8 unk5;
    /* 0x06 */ u8 id;
    /* 0x07 */ u8 spriteX;
    /* 0x08 */ u8 unk8;
    /* 0x09 */ u8 unk9;
    /* 0x0A */ s8 direction;
    /* 0x0C */ u16 region[2];
    /* 0x10 */ u16 rotation;
    /* 0x12 */ u16 unk12;
    /* 0x14 */ s32 unk14;
    /* 0x18 */ s32 unk18;
    /* 0x1C */ Vec2_32 qUnk1C;
    /* 0x24 */ Vec2_32 qPos;
    /* 0x2C */ SpriteTransform transform;
    /* 0x38 */ Sprite s;
    /* 0x60 */ Hitbox reserved;
} Marun; /* size: 0x68 */
```

You know that the `Sprite` has the following structure:
```
typedef struct {
    /* 0x00 */ u8 *tiles; // in VRAM
    /* 0x04 */ u32 frameNum;

    // Bitfield description from KATAM decomp
    /* 0x08 */ u32 frameFlags; // bit 0-4: affine-index / rotscale param selection
                               // bit 5: rotscale enable
                               // bit 6: rotscale double-size
                               // bit 7-8: obj mode -- different (1 bit) in SA3?
                               // bit 9
                               // bit 10 X-Flip
                               // bit 11 Y-Flip
                               // bit 12-13: priority
                               // bit 14: Animation finished
                               // bit 15-16: Background ID
                               // bit 17
                               // bit 18
                               // bit 19-25(?)
                               // bit 26
                               // bit 27-29(?)
                               // bit 30
                               // bit 31

    /* 0x18 */ u16 prevAnim;
    /* 0x1A */ u8 variant;
    /* 0x1B */ u8 prevVariant;

    // 0x08 = 0.5x, 0x10 = 1.0x, 0x20 = 2.0x ...
    /* 0x1C */ u8 animSpeed;

    /* 0x1D */ u8 oamBaseIndex;
    /* 0x1E */ u8 numSubFrames;
    /* 0x1F */ u8 palId; // (0 - 15)
