you CAN get SAH to work with the SCP. pm me and I'll send you some fixed table files from Shadow0000. But He has a bigger update, although he still hasn't loaded it, because he has bandwidth issues, been waiting for it since April. Alternatively, you can look through the Sol:A History thread and they're also in there.
Most of the non-SCP campaigns will work on the SCP if the files have been edited by people who know what to change. However, some of them don't look very nice because they're using old nebulae and such, and so they need probably a more in depth update.
