This awesome preset, so I discovered after watching some Far Lands of Bust, is only just missing something: those typical grand ocean/lakes that the beta terrain had. The beta terrain is way more watery then this preset. But fortunately, the solution is very simple: just set the sealevel to 68. It is maybe not the sealevel of beta, but it brings quite back the old balance between water and land. Just wanted to let it know, for those who wants even a little bit more complete beta experience.
I've compared the code in ChunkProviderGenerate.java from Beta 1.7.3 to the code in azd.class from 14w18b.
The following terrain settings had the exact same values in both Beta 1.7.3 and 14w18b:
seaLevel was 64 in Beta 1.7.3 instead of 63.
biomeDepthWeight, and biomeScaleWeight both need to be set to 0.0, in order to get full height variation across all biomes back.
The two settings I couldn't find the value for in Beta 1.7.3 were biomeDepthOffset, and biomeScaleOffset.
I checked the code for ChunkProviderGenerate.java in Minecraft 1.6, and those two settings affect minHeight and maxHeight.
If you've already set biomeDepthWeight and biomeScaleWeight to 0.0, then they seem to affect the height universally across all biomes.
The Beta 1.7.3 code seemed to use a lot of math to determine the minimum and maximum height, and I couldn't quite figure out what numbers I should input there.
So, I've played around with both biomeDepthOffset and biomeScaleOffset, until I got things looking as close to Beta as I could.
If you want to play around with it some more, biomeDepthOffset is minHeight, and biomeScaleOffset is maxHeight.
I've set biomeSize to 2, as I felt that setting was closest to Beta's small biomes.
