translation:
lancer - launch
charger - load
enregistrer - save
fermer - close

tips:
1.I still recomended to change with regedit
HKEY_CURRENT_USER -> Software -> Bullfrog Productions Ltd -> Dungeon Keeper II -> Configuration->Video
"Engine Id" value to 4

2.with dk2tool click "lancer" and check softwarefilter option, click dungeon keeper II to play
it enables texture filtering in software mode :)

3.use 800x600 resolution

I gave this a go and...its made it even worse. Doesn't help that its in french and I don't speak the language
