Extract data from SNApshot

[Targhan]

I don't want to reinvent the wheel: is there a command line tool (win+linux if possible) to extract the data from a SNApshot?
Something like:
snaExtract <input sna> <start> <length> output.bin ?

Thanks!

A SNApshot is just the binary data plus a header:

Not yet but i planned an INCSNA directive...

Yes, I know that already. But it can be more subtle: there can be potential chunks after. Anyway, I just wanted to know if someone had a ready-made tool.

You could do it in Python to get the command line syntax you're after.

Code Select Expand

f = open('filename.sna', 'rb')
f.seek(255) # skip 255 bytes
rest = f.read() # read the rest


Python also has the bytes and bytearray manipulation built-in which would be useful.

My thoughts exactly . Such a great language.

last version of snapshot contains crunched chunks so that's not that easy

But fortunately, I am generating them via Ramlaid's tool, and it does not compact the data.

WinAPE also lets you choose if the data is compressed or uncompressed.

Targhan, is there any way of importing a YM dump into Arkos Tracker?

You should ask this in another thread . No, it would be meaningless or too hard to convert to a real song. However, you can drag'n'drop it to the YM Analyzer and hack some sounds from it.

Do you have a link to this please?

It's inside AT2 itself. Tools > YM Analyzer.
