if I wanna save my savegame files, do I have to just backup the ones that are titled 'SAVEGAME.00' thru 09 ? Or do I ahve to do so with the 'SAVEENGN.00' too? I notice there are other diles as well ending by .00 (SPELLS, LOG, CITYDATA)... As in all they add up to just about 4 Mb, I have no problem storing everything..."Everything" is always a good idea, since you mention it.
However, to directly answer your question, for the first slot, save *.00, i.e., every file with a ".00" extension. For the second slot, *.01, etc. To restore a slot, first delete all files with that extension, then copy back the files with that extension. (Delete first, because some files are not created until certain things happen, and you don't want to muck up your game with those files. Probably it doesn't matter, but it's safer to delete 'em.)
I know it's a DOS game, but I thought people generally ran it under dosbox, which means it's essentially running as a windows application.This is going to sound nit-picky, but to understand is always better.
In general, no app can run "out of the box" on an OS on which it was not designed to be run. The only way to make this happen is with an emulator, which is what DOSBox is: a DOS emulator. Ergo, Arena is not running as a Windows app;
DOSBox is the Windows app. Arena is still running as a DOS app via Windows app DOSBox. That's why DOSBox has to exist; Arena would be thoroughly confused by Windows, as it is an OS that Arena was never designed for.
It is true that you might be able to run Arena in XP or W7
if you know the proper DOS emulation settings that are built in to Windows. If you can succeed in that, you don't need DOSBox. No guarantees that it's even possible, though.
I know I probably sound like Sister Mary Elephant here, but hey, it's what I do.
