zxcv said there will be 4 test version
are you sure about that? because i see him saying that the next one will be the full 2.4
anyway the codetool is just a simple way to put the secret chars in the data.txt
i'll explain better:
double click on codetool, you will see a window that says "enter your cheat code"
then you write "speedy" for example and it will automatically write the line of the secret char in the data.txt
same goes for the code smiter, the_bone and so on
i hope you understand what i said
