An integrated development environment for SNES built upon Eclipse as a platform.
The developed files come as plugin jars which have to be put into your Eclipse 3.8 dropins folder. Afterwards you may want to start Eclipse as usual and select the SNES dev perspective and create a DSNESDS project... it's really as simple as that.
(Source Code Included)
There are three distinct versions which share hardly any common codebase.
Version 3 is hosted here. All three versions are available for download at http://digisalt.wordpress.com/2013/11/05/dsnesds-the-snes-devkit-that-never-was/
