1555 deleted,

No, sorry it's just an .exe

I downloaded your sample and reconverted to wav pcm with sx tool and works great

Looks like the audio of king kong, the decoders identify the data like Ms-adpcm but can't convert

At the moment i have no idea how to reconvert it

RSd it's a ogg vorbis audio, just extract it with a file ripper

Well i found a reconversor to wav pcm
Works great , try with example of above

Just cause Audio it's a raw pcm, if you recode to mp3 or similar and again to raw the game dont' recognize the data

Maybe this helps

Anyway can extract a sample with novasoftware and attach?

This is no reply

Sorry, but, any news about that?

What i can say?
Really nice post, thanks

So am I right assuming that you want an optimized compression algorithm to use in pngs? You could have a look at 7zip. Afaik they use an improved version of deflate. Yap, i have optipng and some png optimizers, but i tried some zlib's codes and i dont' reach the compression of this packers And 7-zi...

Nice idea
