The only choice you have is whether you want to compile the server Renewal or Pre-Renewal. If you use Pre-Renewal, it will automatically work like in official episode 13.2 regarding mechanics and will use the episode 13.2 files (in the pre-re folders). I haven't done that myself before, but I assume you can do that by using the following parameter when preparing your compile: ./configure --enable-prere If you want to go further into the past, you will have to manually revert scripts / data
