自制程序（Homebrew）是什么 ？

自制open in new window 软件 是指为一个封闭生态的系统上开发并使用非正常渠道安装的软件，例如我们将会提到的 Nintendo DSi. 这些软件涵盖实用工具到自制游戏。

自制软件可以在所有 Nintendo DSi 机器上免费、自由地运行，与固件版本或区域无关。 您需要的只是一个入口点和一个SD卡来存储您的自制程序。 本指南中使用的主要入口点将称为 Memory Pit. 但如果 Memory Pit 不可用，您还可以使用其他入口点。

What can I do by modding my system?

• Run Nintendo DS(i) game backups or ROM hacks from your DSi SD card without the need of a flashcard
• Launch any DSiWare (out-of-region and/or 3DS exclusives) from your SD card
• Boot into DSiWare and homebrew applications by holding specific buttons when turning on your Nintendo DSi
• Run old-time classics using various emulators
• Use normally incompatible flashcards
• Redirect your NAND to the SD card using hiyaCFW
• Watch your favorite movies using MPEG4Player
• Display an image (referred to as the boot splash) on system launch
• Play homebrew games

Where can I find homebrew applications?

• Universal-DBopen in new window has most modern homebrew, with nice search and sorting to keep track of what's been updated recently
• GameBrewopen in new window has a lot of older homebrew, however many will only work on flashcards

What should I know before starting?
