A Plugin for 'Visual Novel DS' (avaliable @ http://filetrip.net/file.php?id=8988) but it ALSO includes a modified NDS to allow it to work as a plugin
1) Install 'Visual Novel DS' as normal
You should have a '/VNDS/' folder on your root
2) Extract all 3 files from the plugin into '/_dstwoplug/' folder
3) RENAME the '/VNDS/' folder on your root to '/VN/'
4) DELETE any other copies of VNDS.NDS (other than the one inside '/_dstwoplug/' folder) as these WILL NOW NOT WORK
