Can you create a universal map

[Blooder]

My question is: If I create a map in version 1.23 will it be possible to play it in higher versions(like 1.26)

Depends if it uses typecasting exploit which was patched, or other bugs that were fixed. Generally I recommend making maps for the latest version of WC3 as that is what most people use and what Blizzard supports.

Things are *generally* backwards compatible, with the big exception of the typcasting exploit as mentioned (I seem to recall something about the gamecache being used as a hash before hashtables too, and I think that's impossible now too).

Any reason you're wanting to use lower versions? Have buddies who stick doggedly to an old version or something?
