I don't know how to open .rom files

[SkicoNow]

I recently downloaded Tinke so I could look through the files of my DS ROMs, hoping I was able to view sound files and images from the game. When I tried opening one particular ROM with Tinke, I found that my ROM stores all of its sounds in a file called "SoundData.rom", but I can't seem to find any way to extract, decompress, or even open the file within Tinke. Does anyone have any tips on how to open this kind of file? Thanks.

This file doesn't support by Tinke now. It needs to new plug-in.
