Are the download links working properly? I get to a "this file was removed" type of page.
Deleted not working links.
Now, my home computer is dead, but I'd like to read the change notes/log if possible. Could you link that?
In the installation archive there is an .xls file with complete description of the changes. Also there is readme file with version to version changelog.
Also, was making VDC difficult?
Yes, it was.
Mostly (99%) I used custom modding tools like OCLplus, pickhack1.0 and lately OCL_Improved. The OCL_Improved includes almost every item, which can possibly be modded.
I'd like to try my hand at modding once I get a new computer, but using a hex editor seems difficult. How do you know what's what with a hex editor?
With hex editor you can change known constants directly in the .exe file. To understand where is located looked constant you need primary research. For that purpose you use other tools, the best known is IdaPro Disassembler and HexRay decompiler (extension to IdaPro). Use of those tools implies knowledge of ASM code and C. Also you can try to use the SoftIce debugger.
Personally I am not familiar with those tools, but I have a friend who helps finding new stuff. I should make notice that it is very much time consuming and labour consuming work.
