No, before you do things, I am still confused to use which one, Essentials will take a long time, but has features, ROM hacking wont take much time and is much popular, that's why...
I think I will stick to ROM hacking as after playing Uranium for a bit, it feels weird for a pokemon game...
After playing FireAsh for a little bit, I will decide...
Sorry for disturbing, but the bag you are making wont be useless as I will use for ROM hacking
