nitroscrap is a Susie plugin package for Nintendo DS File Formats.
- axnds.spi: NitroFS (Nintendo DS filesystem) unpacker (special thanks: ndstool)
- ifnscr.spi: NSCR (Nintendo SCreen Resource) decoder
Susie is an old-school picture viewer for Windows, which can support additional formats by adding Susie plugins (*.spi). In Japan, Susie plugin is often used for decoding custom image formats inside a game.
There are several picture viewers that supports Susie plugin. For example:
- Susie
- Linar
- picture effecter
- stereophotomaker
- vix
- A to B converter
- ACDSee (commercial)
My favorite is Linar for browsing, and AtoB Converter for batch conversion.
