Actually the best way would be to release a new install version including:

WoG 3.58
ERA 1.8
Grayface last editor patch (it corrected a lot of bugs triggered when mouse dragging objects. Before its last editor, it was very hazardous to be able to keep a map clean.)
ERM help 2.8.1 (where is the english version link, I can't find it anymore)
DEFka
HD resolution patch
1.08 and 1.09 patch in wog files format, in update folder, not installed. The snow underground gate from 1.08/09 patches needs subtype fix, as it crashes the game.

Atm, one needs to download all those from different links, which are hard to find, scattered in two languages forums often . And they all are very precious.

If there is any routine work to do, I will help gladly, just let me know.
