Thanks for clearing that up, I thought I read somewhere on the thread that is was that Mod that constricted the pack to mainly have that Wasteland Biome.Steve's Barren Lands is indeed made specifically for the pack, but it's not what I use to generate the wasteland only. Its function is to stop trees, flowers and sugar cane from spawning in beach biomes.
I use Climate Control to disable Vanilla biomes, since as far as I can find, its the only mod capable of disabling vanilla biomes in 1.7.10. Both BoP and EBXL are supposed to have this functionality, but something in 1.7.10 broke it for them. The cracked sand is just EBXLs wasteland biome, and I use COFH Core to generate large amounts of it to nearly completely replace (a few blocks sneak through untouched) grass and dirt blocks around sea level in the beach and ocean biomes.
