spawn? Yes and no; you can decrypt your save with sdf and edit with pkhex, but for editing encounters; your on your own, iirc kazo had a script to edit hoards to have all shiny volcanion
edit: kazo's code

If you're using a Old 3DS you can use the Spider exploit to edit encounter tables, you can also decrypt the ROM and modify the encounter tables so your desired Pokemon appear in the wild at a location of your choice, that's very easy to do actually
