Ok, I have gone through and done some editing of my own. There's a lot of warnings with a debug build, but nothing that stops the game, and it works with a regular build too (3.6.9 even). You won't need the cache files from this post if you use my models, you'll need to make new ones or use the ones I'm posting now. You will need the first and third files in this thread though. I put them all here for easy access.
Make a folder in your FS2 directory (named TOSBSG or BSGAlpha or whatever you want).
Create a folder inside of it called 'data'.
http://rapidshare.com/files/85382078/RaptorsBSGAlpha.rar.html - Extract this into the data folder directly.
http://rapidshare.com/files/85502489/RaptorsBSGAlpha-icons.rar.html - Extract this into the data folder, and move the icons.tbl file into the table folder.
http://swc.fs2downloads.com/files/bsg_data_20080123.7z - Extract directly into the data folder.
http://swc.fs2downloads.com/files/bsg_data_cache_20080123.7z - (Optional, but loading times can be painfully long without it if your pc is a bit older) Create a folder called 'cache' inside data, and extract this directly into it.
Now just select the first folder you created as a mod in the launcher. To use it with Fred 3.6.9, create a shortcut to the fred build, edit its properties and add the options -fredhtl and -mod <folder> at the end, so that it looks something like this (mine is just an example):
D:\Games\FS2SCP\FreeSpace2\fred2_open_3_6_9.exe -fredhtl -mod bsgalpha
If you have quotes around your path to fred, put the options after the quotes.
There is one test mission, with every ship in the pack playing dead, and you flying a Mk2. I used it for testing for holes in the ships. The Protector and the Cylon AF currently have a few areas with issues, I reconverted all the models using Bob's latest (1/21) PCS2 build. If he fixes any more issues I'll redo it. I was considering editing the pof data and adding subsystems and such, but I just didn't have the patience to do that right now. Someone else can, or I'll do it later. Have fun.
