long camp question, question about other campaigns

[sp_fan_ny]

I really have 2 separate questions
1 - I played the old SSI dos-based steel panthers a lot and only found winSPWW2 within the past 6 months or so. the long campaign, starting as Germany in the Sept 1939 time frame seems to have a lot of points (and an allowable core of 200 units), and the battles seem long (40 turns). Do the points used to build the core "roll over" to be available for upgrade/repair between battles? And is there a way to affect the size of the battles?
2 - Is there a way to convert the old SSI campaigns - such as the north africa/afrika corps one - or does a north africa campaign and/or a russian front campaign exist somewhere?
thanks
