# Frequently Asked Questions

## Does homebrew have any risks?

Obecnie, uruchomienie oprogramowanie Homebrew nie naraża Cię na ryzyko zablokowania konsoli przez Nintendo, chyba że oszukujesz w gra lub w sklepie eShop. Zawsze jednak powinieneś zachować ostrożność podczas uruchamiania pobranego homebrew, zwłaszcza jeśli nie ufasz źródłom, ponieważ homebrew może potencjalnie uszkodzić twój system!

## What are exploits?

Exploity to punkty wejścia, które pozwalają na uruchamianie aplikacji homebrew. In the main guide, you will use exploits such as the browser exploit (http://wiiuexploit.xyz) and PayloadLoader (Health & Safety exploit). All current exploits load `SD:/wiiu/payload.elf` which takes over further loading of homebrew.

## What are payloads?

Payloads, which are normally found with the filename `payload.elf`, exist to make it easier to have different exploits load the same next stage, which allows easier updateability. Nie ma znaczenia, jaki exploit ładuje payload, efekt jest zawsze taki sam.

Multiple payloads can be switched between using the PayloadLoaderPayload.

The payload used in the main guide is CustomRPXLoader which loads `SD:/wiiu/payload.rpx` and the `payload.rpx` used in the guide is EnvironmentLoader, which allows you to load different environments.

## What are environments?

An environment is a collection of "setup modules", which will be run in a certain order when launching the environment. Such environments are Aroma and Tiramisu.

Setup modules are small pieces of homebrew/code that are executed once to set up an environment.

## Can I install homebrew on Wii U with a USB instead of SD Card?

No, you must have an SD Card for a first time setup. A USB can then be used to install game backups, Virtual Console injects, etc, but not to store homebrew applications which are required to set everything up.

## When extracting some of the files there are duplicates of certain ones called "info.json" & "manifest.install", what do I do with those?

Nic specjalnego, możesz je tam zostawić, usunąć lub zastąpić nowymi. Those files are not used in the process, and therefore, won't have any impact by being or not being there.

## What is a Wii U formatted USB drive?

It's a USB drive that has been formatted by a Wii U console to its proprietary format.

A Wii U formatted USB drive _**cannot be read by any other devices than the Wii U that originally formatted it.**_

If you ever want to use it with another Wii U console or any other devices, you will have to reformat it.
