LittleWriter to write games to the cartridges. However, some people (especially people with older computers) use other software to write games to the cartridge. An example of this software is X-ROM Frontend by DanSoft Australia. Some flash cartridges use specialized software designed for the specific cartridge, such as Power Writer and USB Writer software for the Flash2Advance Ultra cartridges. This presents several conflicts in regard to homebrew, as Power Writer uses a large database for proper naming and saving of games. ROMs that are not in the database (such as emulators or any other GBA homebrew) are prone to saving issues, and editing the database manually is difficult and involves the use of a hex editor. Such cartridges often have a proprietary interface, making it difficult or impossible to use operating systems other than Microsoft Windows for writing to the cartridge with a few exceptions. Other Nintendo flash cartridges Flash cartridges are also available for other Nintendo consoles, such as the DS, DSi, and the 3DS. The DSi and the 3DS have the ability to update their system firmware via the Internet, which makes it possible for Nintendo to fix the exploit that allowed the flashcarts to work, and essentially block the flashcart from loading on the console. There are also project files existing on the Internet that guide people through creating their own flash cartridge for the original Nintendo Game Boy. Legality The legality of flashcarts has been called into question many times, primarily by Nintendo. In a 2010 high court case, the court ruled in Nintendo's favour, and flashcarts were outlawed in the United Kingdom. Official flash cartridges Some game consoles have official flash cartridges (and official emulators) used by developers to test prototypes of their games. These cartridges are usually part of the console's software development kit and are only available to licensed developers.
