Hello,
I'm a new member and i'm using vx ace.
I wonder where i can find the documentation of the hidden Zlib module, googling don't bring me any answer, i discovered its existence by looking to a script which extends it.
I want to know more, please help ^^

zlib is normally an extension module which they have implemented into RGSS so you can use it natively. They have not provided any documentation about using zlib
You can find the documentation about it here: http://www.ruby-doc.org/stdlib-1.9.3/li ... index.html

Thanks, I thought it wasn't a full implementation, now it's obvious I should look to the ruby-doc
