save/load w/ game cache?

Alright I've been trying to make a save/load system for a while now, with no luck. My latest idea come to using a game cache to store the unit to a specified category in an imported game cache that comes with the map. I would like to know if this can work before I waste my time trying.

edit: also, i read somewhere that you can make a save/load system with UMSWE, which is great, except for one thing. IT WONT LOAD MY DAMN MULTIBOARD!! anyone know what the problem is?

If your map is a multiplayer map then you shouldn't use game cache for the save/load code.
If its single player then you can use cache.
Heres a good tutorial on game caching
About the multiboard thing, it might be because you put the multiboard actions under the "map initialization" event. But maybe because umswe's multiboard functions are different from the normal WE.

Hope this helps.

Is there any game in WarCraft that is single player?

Campaigns, Game Cache is used frequently on them.

Do you think people on BNet are going to make a 1 player campaign?
