-Things I can't get to match:
-1. data->unk0_1 bitfield behaviour. The way bits are read is different.
-2. sprite->oam.priority--; sprite->oam.priority++; Nonmatching version tail-merges these, original does not.
-3. sprite->pos2.x = (gSineTable[data->unk2] * var) >> 8; data->unk2 is very weirdly read at seemingly random moments inside the switch.
-4. sinVal r6/r7 mismatch.
