Chameleon Mod: Additional Partition Type, fails to work

Hi, I need to add another partition type to Chameleon. My laptop has a recovery partition, type 0x1c, which is used to boot windows, type 0x07, which cannot boot without it. Because of this, I'd like to hide my windows partition - easy, using com.apple.boot.plist, and then change the recovery partition's icon from a generic drive to the ntfs icon. I don't plan on changing the partition type, as that makes sure the partition is not seen by normal operating systems, I'm just trying to change the source code of chameleon.
chameleon.osx 86.hu/file_download/40/Chameleon-2.0-RC4-r684-src.tar.gz

At the moment, in ./i386/boot2/gui.c, I have added an extra case to the drawDeviceIcon switch, which identifies the 0x1c type and tells Chameleon it's an NTFS drive.

Now, when I try to boot this, Chameleon fails and defaults to the text prompt, do I need to change anything in libsaio? There are a lot of file, so it is confusing me at the moment, but I can't tell why it won't work, does anyone know how to enable debug mode on chameleon as well, so that I can see where it's gone wrong? Thanks!
