Now to the things I noticed...
In Audio2DScripts.xml...
1) Most of the sounds have <iMinVolume> and <iMaxVolume> set to 100. It is only the last few sounds at the bottom of the file that are set to 75. Why is this?
Yes should be 100, the ones that have 75 were just copy/pasted is all.
2) Some techs are formatted AS2D_TECH_WORD1_WORD2, while some others are formatted as AS2D_TECH_Word1Word2. Just thought I'd mention this.
That is correct, some are upper and some lower(remember what i said they have to match EXACTLY the same), because the "lower" cased ones were a again copy/pasted from another modmod, SHOULD all be capital letters.
3) I found that ArmoredWarfare tech was spelt ArmoreWarfare in both Audio2DScripts.xml and AudioDefines.xml. So there's an extra tech there that should be working now!
Again more than likely just a copy/paste from another modmod, stuff there doesn't mean they are correct, just go ny MY example i had in the above referenced thread.
In CIV4TechInfos.xml...
4) I cannot find Canal Systems
You need a program called "grepWin" its the best search program for files and a very fast one at that.
5) <Type>TECH_BARK_WORKING</Type> had the property <Quote>TXT_KEY_TECH_WOOD_WORKING_QUOTE</Quote>
This is confusing. The quote tag should match the tech tag right?
Again more than likely a copy/paste (mainly this was done just to put something that was not there before) again go by the example i used. They need to match.
5a) I found in RoM_GameText_Civilopedia_Quotes.xml, that the quote for Bark Working in C2C is tagged TXT_KEY_TECH_WOOD_WORKING_QUOTE
See above
5b) Fix this later, audio quotes is what I was meant to do now. I have a feeling this problem is just a bit big for now.
Not really, actually really simple to do. Again just go by the example ONLY.
6) Damn I found something similar to 5). TECH_PARIETAL_ART is actually PETROGLYPHS, I assume some of these are RoM names.
Again "could be" i was lazy before and just put stuff there to have at least something there is all.
