Extension doesn't show when starting campaign

[Hamish]

I have created an extension, but I am unable to select it when starting the campaign, so I guess there's a mistake somewhere. I compared with the Dungeon Theme extension, and to me my extension looks alright.

What are the most common mistakes here? Why wouldn't it show up?

It would be helpful if you could post your extension <properties> tag's content here. However, the common mistakes is with the name, ruleset and dependencies tags in my case.

Here's the entire extension.xml


<?xml version="1.0" encoding="iso-8859-1"?>
<root version="2.0">
<properties>
<name>Drag Hotkeys</name>
<version>1</version>

<author>Nils van Schaik</author>
<description>3.5E ruleset drag to hotkeys extension</description>

<ruleset>
<name>foundation</name>
</ruleset>
<ruleset>
<name>3.5E</name>
</ruleset>
</properties>

<base>
<includefile source="charsheet_abilities.xml" />
<includefile source="charsheet_combat.xml" />
<includefile source="charsheet_main.xml" />
<includefile source="charsheet_skills.xml" />
<script name="ChatManager" file="scripts/chatmanager.lua" />
</base>
</root>

that looks valid to me. Next question is what ruleset are you using? You list 3.5E and foundation in the your extension's ruleset dependencies. You might not be using d20_jpg, 4E or some other?

[Hamish]

In the launcher it says 3.5E for my campaign, so that should not be a problem. I also tried removing the ruleset tags from extension.xml altogether, but that did not help.

I have checked the filenames and they are all correct. I'm stumped....

[Hamish]

OK, solved for now. I'm guessing is has something to do with the method of compression. Using Windows 7 to compress the folder does not work, using 7-Zip to compress the folder does not work. Opening an existing extension in 7-Zip and replacing all contents with my own makes it work. Unless I unwittingly changed something else along the way..... doesn't make sense, but I've got a working extension now.

what I have noted in the past is that it has to be compressed in zip format before changing the extension to ext or mod.

there is something about 7z and rar compression ratios that FG does not like.

it is ok to use winrar or 7-zip as long as you select zip as the archive format before archiving.

Yea. It is important to note that FG2 only recognizes vanilla zip compression. Not RAR or 7z.
