doom ds

I want to know how to set up doom ds,, I have looked at different ways to do this, and it seems there are a few different ways to set it up. so can someone that HAS ACTUALLY DONE IT RIGHT, tell me how to do this,, and also, is there a way I can play w/ doom mods??

which versions of pc doom can this play?? I know it can play doom 1,, but can it play doom 2 and ultimate doom?? and if I were to put all those on there,, can I switch between games??

also I only have an android phone to work...
