What? I'm not MrDollSteak, I'm Telinc1 and the only ROM Base I've ever released is the Ultimate Decapitalisation patch. And no, Pokémon ObsdianBlack/PewterWhite is not a ROM Base and it doesn't use the Decap. and Attack Rombase.
Speaking of which, if you want to use ObsidianBlack/PewterWhite as a ROM Base, I'm very sorry I can't allow you as they aren't meant to be base hacks.
