6 Different ROM Hacks and 4 ROMbases

I have 6 different ROM hacks and 4 ROMbases I would like to work on. They are:
-Pokemon Gold
-Pokemon Polished Crystal
-Pokemon FireRed
-Pokemon Emerald
-pokeruby
-pokeemerald
-Pokemon FireRed ROMbase
-Pokemon Emerald ROMbase
-pokeruby ROMbase
-pokeemerald ROMbase
I won't be able to do all of these. If anyone wants to help, let me know. I have a pretty good grasp or can learn relatively easily for these.

Are these 6 different ideas or are they custom rombases you've made?
