UAE4ALL & DCaSTaway questions

Hello, I am preparing to throw together chui's UAE4ALL and DCaSTaway and had a couple small questions.

On Chui's site it says you need bios files for both of them, which I have, however, I have noticed on the net that there are different versions of these bios's. Will I be fine with the ones I have?

I have the kick bios for the amiga 500 emu that i believe is version 3.1, however, i noticed there are two other versions out there (1.3 and 2.0). Do all the amiga bios's work the same for the DC emu?

I also have TOS 100 for Atari ST emu but have noticed there is a TOS 206 floating around out there. Same question here.

I would prefer to use the ones I have and not download that sort of thing over the internet, however, if the ones i have will not work, i guess i will have to do what i have to do.

thanks for the help
