The Hacks Guide Wiki is still being made and the kinds of content that fits on the site is still being decided. However, certain kinds of guides or resources are prohibited.
Piracy
Tools and websites used to access and download copyrighted content are not allowed on the Hacks Guide Wiki. Do not post guides on how to download paid games for free. Do not link to pre-patched ROMs. Do not link to or post guides on how to use private SDK tools by Nintendo or any other developer.
Cheating in online games
Do not post guides on how to cheat in online gameplay.
Non-Nintendo guides
The Hacks Guide Wiki currently focuses on Nintendo consoles. This wiki is administrated primarily by the Nintendo Homebrew server on Discord, whose expertise is largely the Nintendo 3DS, Wii U, and Nintendo Switch. Guides for PC games, Xbox, PlayStation, mobile games, and others wouldn't fit here, since we would not be able to provide the same level of support.
Consider instead ConsoleMods.org.
What about PlayStation Vita?
The hacks.guide domain also hosts a Vita hacking guide at vita.hacks.guide, but it is managed mostly by people outside of the Nintendo Homebrew server on Discord. Since our experience is Nintendo consoles, this is a Nintendo-focused wiki.
Game strategy guides
This is a guide about hacking and homebrew. You should instead consider posting your guides to StrategyWiki or Wikibooks.
The status on strategy guides and tutorials for playing game mods/ROM hacks is undecided.
