How can I open these files, and what script should i use

[aluigi]

I have made a big update for my old script:
http://aluigi.org/bms/nbajamfire.bms

If you have other ast files from other games, feel free to provide them so I can improve the script (in case it fails with them)

[MarioSonicU]

I was ableto extract them, but they don't have a file extension.

They are the original names.
And I guess they aren't known formats so guessing the extension would be useless.
