vgmcheck - extract loop and time information from VGMs
Posted: Sun Nov 01, 2009 10:23 pm
UPDATE: version 2.0, which is very very small and coded in C. Go to post 3 for download.
A while back, I wrote a little Linux script to help me get the loop point information from a VGM, so I could convert it to WAV and then to a special format for insertion into Super Smash Bros. Brawl (by way of hacking.) I then realized this would be useful for people working with VGMs in other ways as well, so I expanded it a bit. It now gives the total time, loop start, and loop time of a VGM, all in samples as well as minutes/seconds/hundredths of a second.
It also runs on Windows, thanks to Cygwin. The needed Cygwin apps are bundled in the zip archive. Per the GPL, I should tell you that if you want the source code to the Cygwin apps the Cygwin mirrors will have them under "release."
To use it, drag and drop a VGM/VGZ onto the .bat file (Windows) or run the .sh file from the terminal with the VGM/VGZ as an argument (Linux).
Download (Windows/Linux)
The script and everything else in the .zip file is open source, under varying licenses (see the file LICENSE for details.)
