Hi!
Just wanna let you know how to do it
1) Download 2 files I attached ( so that you can save 2 different games)
2)
Copy them into \SD Card\WARCRAFT II\WC2\save (OR wherever your game is)
3)If you want to save a game go to "save", click on one of those files, then click "Save".
A new file "SAVE1.SAV.sav.gz" will be created
4) The next time you play go to "Load" and click on "SAVE1.SAV.sav.gz"
BTW You can disable the virtual keyboard with "zenokeyboard" Not completely though, but it will be more convenient to build the basic structures.
Enjoy!
