In a comment, a player asked me why the Seed Maker did not work in Rune Factory 2. I will add this warning to my Rune Factory 2 General Guide but thought it merited a brief post here as well.
In most Harvest Moon games, including Rune Factory 2, you must have empty slots in your Rucksack or Pockets if you wish to perform any activity that yields an item. Whether in Harvest Moon DS/Harvest Moon Cute DS or Rune Factory 2, if you attempt to create Seeds using a Seed Maker, you will be unable to do so if you do not have an empty slot in your Rucksack for the resulting bag of seeds. There is no other special requirement in Rune Factory 2 where any of the Makers are concerned. If your Rucksack is full, you will be unable to use the Seed Maker.
Even the game itself will warn you about this potential problem when you press ‘A’ in front of the Seed Maker. You will obtain a prompt to the effect that:
‘Creates seeds from Crops. It won’t work if you don’t have room in your Backpack.’
Seeds, unlike Cheese or Yarn, are treated as tools rather than items and therefore cannot be held in your hands. You need to clear a slot in your Rucksack for the resulting product whenever you wish to use the Seed Maker.
Remember here that when items can be stacked, you need to be aware of the fact that separating ONE item from the stack to use in a Maker will create a new item that cannot be added to the stack and cannot occupy the slot where the original item lived! If you have 9 Tomatoes in your Rucksack and wish to create one bag of Tomato Seeds, therefore, you need an empty slot for those seeds. Unless you use all 9 of the Tomatoes to create 9 bags of seeds, the resulting product will not be able to occupy the slot that the original item occupied.
There is one situation where, even if your Rucksack has sufficient slots for a new Product, you will be unable to use the Seed Maker. This will occur whenever you attempt to create Seeds after accepting any Request. For the duration of any Request, the Seed Maker will not function!
