How do I know if a game is already self booting or not?

[RedsunsFC]

When I dowload a game how do I know if it's already a self booting game or not?
Don`t tell me to burn it down and try it, cause that's the case I wanna prevend. I hate to use the bootdisc.
Other question: which method now is the best to make self booting dc games: After Echelon's guide or using bin2boot or use one of the other selfbooting progs dccopyworld offers? There are other progs like Autoboot.... Are they good too or just crap? Someone tried them out yet?
