No team screenshots, shiny screenshots, or pictures of non-ROM-hack-related sprite art.
Criticism and feedback threads are all right, as long as it's a legitimate call for feedback and not just looking for others to do the heavy lifting. Please contact the moderators if you have any questions. However, specific exemptions are allowed when you're the creator of the hack and you're not spamming. This includes fangames (RPG Maker or similar), Pokémon GO cheats, and general Pokémon/gaming surveys. To share ROM hacks, use patch files instead. This includes, but is not limited to, hacks and ROM bases, and also includes piracy site names. Welcome to /r/PokemonROMhacks, where you can find, create, and discuss hacks of Pokémon games.
