Thanks, but is there any chance someone could explain to me how to use these programs? I am a complete novice to these types of programs and I have no idea where to even begin. Thanks in advance for any help.
If the tools are what I expect them to be, then they're command-line programs. If you're double-clicking it, then you're using it wrong (and it won't work whatsoever). Open a command prompt (start>all programs>accessories> "command prompt"), and browse (for info on how to do this, check here. In brief, use "cd" to change directory, and "X:" to change drive (where "X" is the drive letter). Note - only use the things within the quotations, exclude the " when using the commands I listed here) to the location of the program, and the files (make sure the program and the file(s) in question are in the same directory). Once you're in the proper directory, then you can run the program by typing its file name into the command prompt, and pressing "enter" (see previous note on quotation marks). Usually, this will give you an error message, along with a list of commands and how to use the program. Since I've never used the program currently in question, I can't really help you past this point. Hopefully that will be sufficient to get you started though. Mouser X over and out.
Or you can grab cmdopen shell extension from here. This will allow you to skip the "directory changing" step which might be a bit of hassle. All you need to do is simply browse to the directory containing the programs, right click on the empty space and select "Open Command Prompt" from the context menu.
Now you simply need to type in the program filename, as Mouser X suggested. For fsbii you need to type in the command fsbii filename.fsb , just make sure the file you're willing to convert is present in the same directory as fsbii.
Sorry about that, should be fixed now: fsbii 0.4 (finally)
Another update, 0.5 adds the ability to scan for FSBs embedded in an archive (similar to adXtract's functionality). So it now covers the two main packed FSB styles.
