# Chronotools - signature feature

## 0. Contents

This is the documentation of chronotools-1.15.9.

## 1. Introduction

Chronotools allows you to insert arbitrary SNES code to your translation. This includes a "signature" feature.

Signature is a logo, displayed on the startup screen of the game, as shown below for example:

ATTENTION: This feature is provided for making your publication identified - preventing people claiming it as their own. Do not use it for bragging. I recommend that you will ignore this feature until your translation is ready for test releases.

## 2. How to

If you want to add a signature, the easiest way is as follows:

Add the following lines to your `ct.cfg` in the `[linker]` section:

    # SIGNATURE
    load_code "ct-moglogo.o65"
    add_call_of "show_moglogo"   $FDE62F 0 false
    add_image   "moglogo.tga"    "TILEDATA_ADDR"  "PALETTE_ADDR" "PALETTE_SIZE"

This tells the insertor that it must include code from `ct-moglogo.o65` and insert a call of the routine `show_moglogo` at $FDE62F in the ROM, and that it should read and insert the image `moglogo.tga`, compress it and assign several constants for referring to it.

You can create `ct-moglogo.o65` by compiling the included `ct-moglogo.a65` file with snescom, a SNES assembler, or asking me to send it to you.
