Hi again Aluigi, in some files the script show error, the files begin with @UTF....

This is the message:

-error in src\etra\xalloc.c line 619: xdbg_malloc()

Error: memory allocation problem
Not enough storage is available to process this command

Here's the samples:
b.rar

If I remember correctly @UTF is the CRI framework, the same used in the CPK archives (without the CPK header here).
I don't know what tool should be used on these files.

Exist a tool, but doesn't work with this type of files, maybe be for the lacks of header in files
