So. Did some research. Items are 0x50 long. It doesn't matter where in the inventory you place them, after a quick sort everything should work. Also Item's don't exactly work the way it's described there. The stars seem a bit different, and there is more data after that point, but that doesn't matter. Might consider adding a page to my debugger just for harvest moon. I also tinkered a bit with the animals. The first cow is at Ram address 0x085AFFA6. At least the name. Might do a bit more testing soon, but not today.
