📋 About This Mod
So you finished the community center and realized there are some things you just can't live without. No problem! A shady character in the bus tunnel will be happy to sell you a few goods - at premium prices, of course.
Welcome to the Joja Blackmarket! Manned by fine, upstanding citizens this shop is a purveyor of precious Joja goods, gems, and artifacts. They'll also happily buy any spare swords or monster loot you might have lying around. Where can you find such a marvelous shop? Why, just around the corner from your farm in the conveniently located tunnel! But some of the townspeople have noticed strange things going on and aren't so happy...
Auto-petter (if CC complete)
Random gem (cheaper gems are more common)
Random artifact, slime egg, or other nice prize (common artifacts are more common)
Joja Seeds (must have Joja Seeds)
Joja Fruit Tree Crops (must have Asters Fruit Trees as Crops)
Joja MMOs (if CC complete and Stardew Valley Expanded installed)
Description but boring
If you go in the bus tunnel there is now a "shop" in which Joja goods can be purchased for scalper prices. These prices increase after CC completion. A random gem (x5) and a random artifact (or rarely a slime egg, pearl, golden pumpkin, or dragon tooth) will be available for purchase each day. You can also sell swords, rings, and monster loot to the shop so you don't have to wait for Marlon to open up or if it's 1 and he's already closed.
In addition, a week after CC completion (or a day after you first load the mod on an existing save) you will receive a letter inviting you to the tunnel and some NPCs will have comments about the shady things they've noticed recently.
This mod may also be used to sell JA Joja goods if SVE is installed and you cannot otherwise edit the Joja shop.
Compatibility
Should be compatible with nearly all mods. Does make a change to the tunnel, but I don't know of any other mods that change that spot in it so you should be in the clear.
Can I add an item to the Blackmarket?
Yes! However, you'll need to do the coding yourself. Fortunately, it's very easy!
If you just want to add some items for yourself, you can open up the file "shops.json" in this mod's STF folder and edit it directly. You can reference this tutorial for more information.
If you would like to add some items via a published mod, you are welcome to do so with a caveat: please keep the general theme in mind and also please don't be, like, racist or anything. Be cool.
To do so, you will create your own STF mod. You can use the tutorial linked prior for the basic code, and remember that you do not need to repeat any of the existing items (this would cause the inventory for
