Decompress and decrypt files

[BySc]

I have a file encrypted when I use this code works without probleam,

Code: Select all

goto 4
get size asize
savepos offset
encryption rc4 KEY

get NAME basename
string NAME += ".png"
log NAME offset size

but some of files compressed and ecrypted when I try decompress and decrypt with this code I am getting error.

Error:

Code: Select all

Error: impossible to write 0xefdffd20 bytes (total 0xefdffd20)
       Check your disk space or the script is wrong

Last script line before the error or that produced the error:
  129 log NAME offset size

Decompression code

Code: Select all

    comtype zlib_compress
   get SIZE asize
   clog test 0 SIZE SIZE

For sure a mistake is using SIZE equal to the whole file and an OFFSET which is not zero.
Solution
math SIZE - OFFSET

Thank you but i changed script because with asize not work correctly. I cant share sample file for decompression I guess.

For decryption works with this

Code: Select all

goto 4
get size long
savepos offset
encryption rc4 KEY
get NAME basename
string NAME += ".png"
log NAME offset size

with other file must decompress and decrypt and I am getting error " Can't read byte"

Code: Select all

  goto 4
   get size long
   savepos offset
   #math SIZE - OFFSET
   comtype zlib_compress
   clog test OFFSET SIZE SIZE

Better to share file and name of the game.
