Hi Birdy, and welcome to the MegaGlest forums. I'll try to answer your questions thorougly.
1. How to install a mod om megaglest? I know theres a mod page but it doesnt show things like the Elvish, Dwarven or African mod... So how do you install it?
There's exactly one proper way of structuring a MegaGlest mod. How to do this, depends on the type of mod (techtrees, tilesets, maps, scenarios). What you listed (Elvish, Dwarven, African) are probably either factions or techtrees (which consist of one or more factions and other data). Historically modders who created factions didn't place them in techtrees, but made them available 'as is', to be placed in the existing Megapack techtree. This is no longer supported, so modders need to create their own techtree now, even if they only have a single faction and want to reuse existing Megapack content/data.
If modders have not done this, then you'll need to do it yourself. The best way to get started there is probably to install a proper techtree from the 'Game Mods' menu, such as Japanese, and to take a look at the structure it takes on disk. If you're on Linux, you will see that after installation there is now a directory
~/.megaglest/techs/japanese which contains the actual japanese faction in the
faction/japanese/ subdirectory, as well as containing a set of
resources/ (i.e. a structural and audio-visual definition of those things you can harvest or spend) as well as the
japanese.xml file which glues it all together.
So, for a more applied view, to install those old factions you would place them in
~/.megaglest/techs/NAME_OF_TECHTREE/factions/, and you could place a copy (or a subset of) the resources directory at
~/.megaglest/techs/NAME_OF_TECHTREE/resources/ and finally you would add an adjusted copy (just the techtree and faction names will probably need adjustments) of the XML file at
~/.megaglest/techs/NAME_OF_TECHTREE.xml.
So unfortunately this mean more fiddling than you may want to do. It would be great if some modders could reorganise these old factions for MegaGlest so this becomes easier...
2. I downloaded the Ming and jappanese mod via the mod tab in megaglest. But when you play it you can only be japanse. Is there a way to add the jappanese mod into the megapack? (If you dont understand my question: Can you make a "ultrapack" which includes magic, jappanese, ming, tech, romains, Elves, Dwarfs ect???)
Yes, you can do this in MegaGlest by creating a new techtree ("Ultrapack" is what you call it) with
faction links. These are just references to factions in other techtrees you have already installed so you do not need to duplicate the data. However, this is a somewhat experimental feature and it's not clear whether this would work for playing online. Alternatively you could just duplicate the data, assuming that licensing terms permit/are compatible. Finally, and most importantly, while creating such a huge techtree with lots of factions may initially seem to be desirable and make a lot of sense, you will soon realise it's actually not a good idea, since it is very hard to do the balancing which is needed to make a techtree fun to play, and this gets really difficult as soon as you're talking three or more factions. So while you can create this huge techtree technically, it won't be much or any fun to play, since everyone will just pick the most powerful faction and the others will just die.
3. Can someone post a download link for the woodsman mod? (The download links in the topic dont work...)
While your other questions would fit both places, this one definitely belongs into the
mods forums. And personally I don't know the answer to it.
