Expand Nintendo DS ROM extraction and decompression support

[ci-macpaw]

Matt Sephton (gingerbeardman):

This feature is great and really useful for me. But it misses some files.

Please see output from CrystalTile2 which sees files in FSI.CT area.

The file I was looking for is FSI.CT/overlay9_0002.bin

Also, some files are LZ compressed - such as the one above - it would be nice if you uncompressed them. You can see CT2 marks them with LZ icon.

The game I am browsing is Pang DS (Pang: Magical Michael, 2010)
