I would like to ask for some help.
I worked time ago in what was called "neogeo injections" (change the game form a genuine vc game to another)
http://www.youtube.com/watch?v=5i1W9aLbjRw (old video)
I was able to do "all possible" (they have a maximum file size), but now, in new genuine games, appeared the "game file" compressed (game.bin ->game.bin.z)
The "problem" was the game.bin.z file. And Stev418 and GameZelda suggest a Zlib compresion.
Last week i could decompress that file using offzip (Luigi Auriemma):
I renamed game.bin.z to game.z and then:
"offzip -A game.z game 0x0" (where "game" is the directory where i what to extract the file)
Offset file unzipper 0.3.3 (offzip)
a very useful tool to unpack the zip (zlib/gzip/deflate) data contained in any type of file included raw files, packets, zip archives, executables and anything else.
it's needed only to specify the offset where the zip data starts or using the useful -S search options able to find any possible zip block contained in the provided file.
naturally there are also other options for extracting all the zip blocks which have been found or dumping them as in their original compressed form.
it's also possible to choose a windowBits value for scanning both the zlib (RFC1950) and deflate (RFC1951) blocks (for example -z -15 for common zip files and so on).
I got a file called "00000000.dat" with good data insite, its not a corrupted file (i recognice the content because its more or less the same form "old files", with some modifications)
Now, after the study of 00000000.dat file, i need to compress a new file... (with diferent data in it)
Could you please help me with this?
Thanks in advance.
