Every game has a "1st_read.bin" file, but the name of this file is not always the same (it may be "xyz.bin"). You have to find by yourself the name of this file and "say" this name to the program you are using to make the game selfbootable. If you do it correctly you'll make the game boot with Chankast.
If you don't understand what I say or you don't know how to do it, wait for a Chankast release that supports the utopia boot disk.
