Quick post about 1.7 packs.
For minecraft 1.5 and lower, the FTB launcher, and MultiMC, loaded "jar" mods, such as Forge, from a folder called instMods. With the new vanilla launcher Mojang put out with 1.6, that changed. All the launchers, FTB, MultiMC and the vanilla one, look at certain file called a JSON file to tell what to load. This makes it a heck of a lot easier from a programmers perspective to add new libraries such as Forge, and a number of other ones. Unfortunately, this also means it's a bit harder from the end users perspective to add Forge.
In my case, it has become impractical to have you guys, the modpack makers, add Forge yourselves. It would be possible, but there are a number of little things it would be easy to mess up, and I don't have time to debug it. However, there is a somewhat simple fix to the problem. I can just add Forge for you. This is what I've been doing for all the 1.6 packs. However, this has been possible because Forge is no longer updating for 1.6, so I only have to worry about one version. I can just copy in Forge, in the correct folder, along with all the other libraries it needs, and that JSON file.
1.7 is different. There are lots of versions of Forge. Everyone will want a different one, and it will change between updates. I can work around this, it won't take me long to write something that takes a Forge version number and copies the correct libraries and JSON in. But, due to my school schedule, I haven't had that time.
TL;DR 1.7 is coming soon, still too busy with school stuff right now.
HOWEVER, if you really want a 1.7 pack, I will give you this option. Download the official Unstable pack (
direct link), look at where the forge file is stored and what the pack.json file says and modify it for the version of forge you want. Then copy that pack.json and the entire libraries folder to your pack and submit it. Be sure to mention that you are using this option. I'll upload it as is. If it doesn't work, it's up to you to figure out what's wrong and resubmit it. I will not provide any support. Regular 1.7 support should only be a few more weeks away.
Hint, you should only need to add a new folder with the version number and forge inside it, similar to the one that is under libraries/net/minecraftforge/forge/ , remove the old one and change 2 lines in the JSON. Good luck.
