Sonic Winter Adventures
Hacking Contest 2013 Special
==============================

What's this?
-------------

Sonic Winter Adventures supports working with the Sega Mega CD addon to allow game to play CD-Audio tracks. This is so-called Mode 1. Unfortunately, the only emulator to support this mode so far is Kega Fusion. This package has Kega with working configuration, in case you don't have one.

You still can play Sonic Winter Adventures as an ordinar ROM in any other emulator, including Kega.

.

How to use it?
---------------

Run SWA.BAT to open Sonic Winter Adventures ROM in a pre-configured Kega Fusion emulator. It will run as an ordinar ROM unless you connect CD image to it. To do so, just drag&drop SWA.CUE file onto Kega with working ROM -- the system will reboot with the Sega Mega CD addon attached and CD image loaded into it. If the process was successful, a notification message will pop up.

Unfortunately, Sonic Winter Adventures, while in Sega CD mode, cannot operate SRAM on Kega due to emulator bug. Saving feature won't work and the game won't see save data you have. It doesn't corrupt the actual save data, once you load it as normal Mega-Drive ROM, all your data will be there.

Manual Setup
-------------

In case you want to configure your own Kega to be able to run Sonic Winter Adventures in Mode 1, here are few steps you need to accomplish:

1) Configure Mega CD BIOS files. In case you don't have ones, you can copy them straight from the emulator version, provided here (BIOS folder)

2) Open Fusion.ini file in your emulator folder. In the end of file, you'll see the following line:
CartBootEnabled=0
Change 0 to 1 here and save.

3) Now you can load Sega Mega CD with an ordinar Mega-Drive ROM. Sonic Winter Adventures has a code detecting if Mega CD addon is attached. If it does, it will use additional Mega CD hardware to play CD-Audio.
Unfortunately, enabling CartBoot option in INI-file may break CD games for you. If you'll try to load any CD image with a Mega-Drive ROM openned, Kega will boot in Mode 1, Sega Mega CD games won't load then.

Mode 1 extension wouldn't happen without the help of these awesome guys! I so thankful for you all for providing a proper hardware initialization code, supporting me and answering my noob-ish Sega CD related questions ;)
