>>To get the campaigns to work remove or rename the music folder insider the data folder.
Aha, that's why I had no problems, I deleted the music directory since the beginning.
Yesterday I played a 64x64 (across the streams) with no problems whatsover except that when loading a game within a game sometimes the program would quit, but if I quit the game, start it again and load my saved game, it works. So I'm happy at least there is a work around and the game is very playable now, I'm quite happy with it.
I haven't tried a 128x128 game yet.
I also tried this special QVGA version in VGA mode! It works if you edit the preferences2.lua in the wc2 directory and set the mode to (480,640). The game will work, but in a small window on the top left corner of the screen. This is good for vga users who do not want to reset their PPC to switch to QVGA mode.
Hopefully the newer versions will require less memory. The newest executable only requires 16 mb of ram.
