But now my son came up with that new, apparently uber-cool game from nick.com called "Avatar - Legends of the Arena", and he really wanted me to make it work with his machine. Unfortunately this game is - of course - only available for Windows, and it needs an internet connection - something I was not willing to enable on the Windows installation.
The way out of the dilemma: WINE.
There were only minor problems, e.g. that the game would install, but then still could not connect to the game server, but a look at the console output showed
fixme:wininet:InternetSetOptionW Option 28 STUB
fixme:wininet:InternetSetOptionW Option 29 STUB
And with the help of Marcus Meissner (also here), we found out that all that was needed to get it going was that the original W2K wininet.dll had to be copied to ~/.wine/drive_c/windows/system32/ and then the game could be started with
WINEDLLOVERRIDES="wininet=n" wine AvatarMP.exe
Cool stuff, WINE developers!
Now the next thing to get going is the TomTom Software ;)
